Periodicals, whatever their medium, play a critical role in the information society, and more specifically in the global information infrastructure. Citations to articles in scholarly journals, whether in print or in electronic journals, form the basis for much scholarly research. Popular trade magazines as well as newsletters are used by authors, researchers, and students of all ages. Search, discovery, and use of the wide range of today’s periodicals require that they provide reliable identification and display of key information by following standardized principles and procedures.

This document is applicable to a subcategory of continuing publications identifiable as "periodicals" (see Clause 3). Newspapers are not generally considered to be periodicals and therefore specialized information relevant only to newspapers is not included. This document does not specifically address or apply to books, including series of books, nor to content that is continuously updated such as loose-leaf services, databases, online reference works, and most websites. (For information about series titles, see ISO 7275.)

Presentation and identification of periodicals is a broad and detailed topic but this document deliberately focuses on only those elements of periodicals—printed, born-digital or retrospectively digitized—that relate to the presentation of title and supporting descriptive information, plus practices related to title identification and content access over time. Therefore, this document is not concerned with the overall design of the periodical, except where that design affects the presentation of the title, and has unintended consequences for resource discovery and access to earlier content. Neither is it concerned with the technical specifications for print, born-digital or digitized periodicals. The recommendations are of varying importance and may not always accommodate certain artistic, technical or advertising considerations.

The recommendations address the following:

— Display of periodical title(s) and other critical identifying information: issues, numbering systems, pagination, etc.

— Retention of title and citation information under which articles were originally published.

— Display of title histories, including information relating to major title changes.

— Specification of appropriate metadata for digital periodicals. (Note: this document concentrates on metadata elements which are applicable at the title-level and does not provide guidelines for complete article-level metadata.)

— Display of correct ISSN, including different ISSN for each format, language edition, and for changed titles.

— Retention and display of vital publication information across the history of a periodical, including publisher names; clear numbering and dates; editors, editorial boards, and sponsoring organizations; and frequency of publication.

— Graphic design that supports clarity and consistency of information, particularly title information and inclusion of information that allows easy access to all content.

— Special considerations for retrospective digitization.

— Usage of persistent identifiers for identification of periodical titles and articles.

— Long-term preservation of periodical information across time.

This document contains recommendations intended to enable editors and publishers of periodicals to identify and present key information in a form that will help users discover, cite and access their information over time and through any changes. This will benefit all stakeholders of the periodical supply chain: publishers, content providers, authors, librarians, and researchers.

This International Standard specifies the characteristics of hexagon socket countersunk head screws with reduced loadability due to head design, in steel and stainless steel, with metric coarse pitch threads M2 to M20, and with product grade A.

NOTE The reduced loadability (related to the countersunk head dimensions in combination with penetration of the hexagon socket specified in this standard) implies a limitation of ultimate tensile load, see Table 3.

This document specifies, with reference to ISO 230‐1 and ISO 230‐7, the geometric tests for general‐purpose, numerically controlled (NC) turning machines and turning centres with vertical workholding spindles, as well as the corresponding applicable tolerances.

This document explains different concepts or configurations and common features of NC turning machines and turning centres with vertical workholding spindles. It also provides a terminology and designation of controlled axes (see Figures 1, 2, 3, and 4).

This document deals only with the verification of the accuracy of the machine. It does not apply to the operational testing of the machine (e.g. vibration, abnormal noise, stick slip motion of components) nor to machine characteristics (e.g. speeds, feeds). Tests not concerning the geometric accuracy of the machine are dealt with in other parts of ISO 13041.

This document specifies the requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of non-pressure underground drainage and sewerage:

— buried in ground outside the building structure (application area code "U"), and

— both buried in ground, within the building structure (application area code "D") and outside the building.

This is reflected in the marking of products by "U" and "UD".

It also specifies the test parameters for the test methods referred to in this document.

NOTE 1 Solid wall multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by EN 13476-2 [1] (see also CEN ISO/TR 27165 [2]).

This document covers a range of nominal sizes, a range of pipes and fittings series and a range of stiffness classes and gives recommendations concerning colours.

NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

In conjunction with prCEN/TS 1401-2 [3], it is applicable to PVC-U pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping systems for non-pressure underground drainage and sewerage.

NOTE 3 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 7 and to the requirements of Table 15.

This International Standard specifies performance requirements and test methods under prescribed laboratory conditions for the evaluation of pumped samplers used in conjunction with an air sampling pump and of procedures using these samplers for the determination of gases and vapours in workplace atmospheres.

NOTE For the sampling of semi-volatile compounds which can appear as a mixture of vapours and airborne particles in workplace atmospheres see EN 13936.

This International Standard is applicable to pumped samplers and measuring procedures using these samplers in which sampling and analysis are carried out in separate stages.

This International Standard is not applicable to:

— pumped samplers which are used for the direct determination of concentrations, for example, length-of-stain detector tubes;

— samplers which rely on sorption into a liquid, and subsequent analysis of the solution (bubblers).

This document specifies a test procedure, environment and instrumentation for measuring the exterior sound pressure levels from road vehicles under stationary conditions, providing a continuous measure of the sound pressure level over a range of engine speeds. This document applies only to road vehicles of categories L, M, and N equipped with internal combustion engines. Vehicles where an internal combustion engine cannot operate when the vehicle is at stationary conditions are not within the scope of this document.

The method is designed to meet the requirements of simplicity as far as they are consistent with reproducibility of results under the operating conditions of the vehicle.

It is within the scope of this document to measure the stationary A-weighted sound pressure level during

— type approval measurements of vehicle;

— measurements at the manufacturing stage;

— measurements at official testing stations;

— measurements at roadside testing.

This document specifies neither a method to check the exhaust sound pressure level when the engine is operated at realistic loads nor a method to check the exhaust sound pressure levels against a general noise limit for categories of road vehicles.

Technical background information is given in Annex A.

This document specifies a method for the determination of fish acute toxicity using the permanent cell line from rainbow trout (Oncorhynchus mykiss) gill, RTgill-W1. Cells in confluent monolayers in 24-well tissue culture plates are exposed to water samples, such as surface waters or different kinds of effluents, or to chemicals for 24 h and thereafter, cell viability is assessed based on fluorescent cell viability indicator dyes (see 4.1). Data are then expressed as % of unexposed control and toxicity quantified based on % cell viability vs. % effluent or chemical concentration response curves (see Clause 9).

This document specifies a method for detection of HAV and norovirus genogroups I (GI) and II (GII), from test samples of foodstuffs (soft fruit, leaf, stem and bulb vegetables, bottled water, BMS) or food surfaces. Following liberation of viruses from the test sample, viral RNA is then extracted by lysis with guanidine thiocyanate and adsorption on silica. Target sequences within the viral RNA are amplified and detected by real-time RT-PCR.

This method is not validated for detection of the target viruses in other foodstuffs (including multicomponent foodstuffs), or any other matrices, nor for the detection of other viruses in foodstuffs, food surfaces or other matrices.

This document specifies methods for the measurements of magnetic susceptibility of soils (κ) as an indicator of soil pollution with trace elements associated with Technogenic Magnetic Particles (TMPs) and describes related procedures, protocols and guidelines to be applied as a screening geophysical method of evaluation of soil pollution with trace elements. The results of measurements are used for preparing the maps of magnetic susceptibility of soils in the area of interest. From these maps, the areas of elevated and high magnetic susceptibility indicating high trace element total pollution load are discriminated for further identification of pollutants by geochemical methods.

This document is applicable to screening all TMPs-related anthropogenic emission sources including long-range transport of airborne elements, of which TMPs are carriers and indicators. Such emission sources comprise the majority of high-temperature industrial processes, where iron is present in any mineralogical form in raw materials, additives or fuels, is transformed into ferrimagnetic iron oxides (e.g. fossil solid and liquid fuels combustion, metallurgy, cement and ceramics industry, coke production, industrial waste landfills, land transport, etc.). This document is not applicable to screening anthropogenic emissions not associated with TMPs, e.g. organic pollutants or emissions from agricultural sources

NOTE Copper, zinc and other non-ferrous metal ores also contain iron (in many sulfides) as this element is abundant in almost all environments. During smelting, the iron occurring in sulfides is transformed into ferrimagnetic oxides (TMPs). However, in such cases, the proportion of TMPs and related PTEs is usually less than that at coal combustion or iron metallurgy, for example, and not all PTEs are physically associated and transported by TMPs. Non-airborne elements are deposited in the close proximity of the emission source, while TMPs can be used in these cases as indicators of airborne elements and of the spatial distribution of the total element deposition from a smelter in the area.

In rare cases, some soils are developed on the bedrock of the geogenically high magnetism, which may cause false-positive results. This influence can be though easily indicated by measurements of magnetic susceptibility along soil profiles. If the local bedrock exhibits extremely high magnetic signals, this method shall not be applied. Such cases are though exceptional.

This document specifies a method of evaluating the ultimate anaerobic biodegradability of plastic materials in a controlled anaerobic slurry digestion system with a solids concentration not exceeding 15 %, which is often found for the treatment of sewage sludge, livestock faeces or garbage. The test method is designed to yield a percentage and rate of conversion of the organic carbon in the test materials to carbon dioxide and methane produced as biogas.

The method applies to the following materials, provided they have a known carbon content:

— natural and/or synthetic polymers, copolymers or mixtures;

— plastic materials that contain additives such as plasticizers, colorants, or other compounds;

— water-soluble polymers.

It does not apply to materials which exhibit inhibitory effects on the test microorganisms at the concentration chosen for the test.

NOTE Inhibitory effects can be determined by an inhibition test (e.g. ISO 13641-1 or ISO 13641-2).

This document specifies a method for determining the ultimate aerobic biodegradability of plastic materials in soil by measuring the oxygen demand in a closed respirometer or the amount of carbon dioxide evolved. The method is designed to yield an optimum degree of biodegradation by adjusting the humidity of the test soil.

If a non-adapted soil is used as an inoculum, the test simulates the biodegradation processes which take place in a natural environment; if a pre-exposed soil is used, the method can be used to investigate the potential biodegradability of a test material.

This method applies to the following materials:

— natural and/or synthetic polymers, copolymers or mixtures of these;

— plastic materials which contain additives such as plasticizers or colorants;

— watersoluble polymers.

It does not necessarily apply to materials which, under the test conditions, inhibit the activity of the microorganisms present in the soil. Inhibitory effects can be measured using an inhibition control or by another suitable method. If the test material inhibits the microorganisms in the soil, a lower test material concentration, another type of soil or a pre-exposed soil can be used.

1.1 This document specifies methods for the determination of the water content of plastics in the form of powder, granules, and finished articles. These methods do not test for water absorption (kinetics and equilibrium) of plastics as measured by ISO 62.

Method A is suitable for the determination of water content as low as 0,1 % with an accuracy of 0,1 %.

Method B and Method C are suitable for the determination of water content as low as 0,01 % with an accuracy of 0,01 %. Method D is suitable for the determination of water content as low as 0,01% with an accuracy of 0,01%. Method E is suitable for the determination of water content as low as 0,001% with an accuracy of 0,001%. The stated accuracies are detection limits which depend also on the maximal possible sample weight. Percentage means percentage of water content.

Method D is suitable for polyamide (PA), polycarbonate (PC), polypropylene (PP), polyethylene (PE), epoxy resin, polyethylene terephthalate (PET), polyester, polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), polyactide (PLA), polyamidimid (PAI), it is especially not recommended for samples which may release NH3. Method E is generally suitable for every type of plastic and moisture level.

Water content is an important parameter for processing materials and has to remain below the level specified in the appropriate material standard.

1.2 Six alternative methods are specified in this document.

— Method A is an extraction method using anhydrous methanol followed by a Karl Fischer titration of the extracted water. It can be used for all plastics and is applicable to granules smaller than 4 mm × 4 mm × 3 mm. The method can also be used for, e.g. prepolymer materials in the form of a powder that are insoluble in methanol.

— Method B1 is a vaporization method using a tube oven. The water contained in the test portion is vaporized and carried to the titration cell by a dry air or nitrogen carrier gas, followed by a Karl

Fischer titration of the collected water. It can be used for all plastics and is applicable to granules smaller than 4 mm × 4 mm × 3 mm.

— Method B2 is a vaporization method using a heated sample vial. The water contained in the test portion is vaporized and carried to the titration cell by a dry air or nitrogen carrier gas, followed by a Karl Fischer titration of the collected water. It can be used for all plastics and is applicable to granules smaller than 4 mm × 4 mm × 3 mm.

— Method C is a manometric method. The water content is determined from the increase in pressure, which results when the water is evaporated under a vacuum. This method is not applicable to plastic samples containing volatile compounds, other than water, in amounts contributing significantly to the vapour pressure at room temperature. Checks for the presence of large amounts of volatile compounds are to be carried out periodically, for example by gas chromatography. Such checks are particularly required for new types or grades of material.

— Method D is a thermocoulometric method using a diphosphorus pentoxide (P2O5) cell for the detection of the vaporized water. The water contained in the test portion is vaporized and carried to the sensor cell by a dry air or nitrogen carrier gas, followed by a coulometric determination of the collected water. This method is not applicable to plastic samples containing volatile compounds, other than water, in amounts contributing significantly to the vapour pressure at room temperature. This is specially related to volatile components which may react with the acidic coating of the diphosphorus pentoxide sensor, e.g. ammonia or any kind of amines. Checks for the presence of large amounts of volatile compounds are to be carried out periodically. Such checks are particularly required for new types or grades of material.

— Method E is a calcium hydride based method. The water content of a sample evaporates due to a combination of vacuum and heating. The evaporated water reacts with calcium hydride to molecular hydrogen and calcium hydroxide. The hydrogen causes an increase of pressure in the vacuum that is proportional to the evaporated water. Volatile adhesives, that do not react with calcium hydride condensate in a cooling trap and will not affect the measurement.

This document provides general principles for the systematic evaluation of the potential and observed degradation of medical devices through the design and performance of in vitro degradation studies. Information obtained from these studies can be used in the biological evaluation described in the ISO 10993- series.

This document considers both materials designed to degrade in the body as well as materials that are not intended to degrade.

This document is not applicable to:

a) evaluation of degradation which occurs by purely mechanical processes; methodologies for the production of this type of degradation product are described in specific product standards, where available;

NOTE Purely mechanical degradation causes mostly particulate matter. Although this is excluded from the scope of this document, such degradation products can evoke a biological response and thus need to undergo biological evaluation as described in other parts of ISO 10993.

b) leachable components which are not degradation products;

c) medical devices or components that do not contact the patient's body directly or indirectly.
