This International Standard specifies a method of determining the apparent density and tap density offree-flowing uranium dioxide (UO2) powder which will be used for pelleting and sintering of UO2 pellets as a nuclear fuel.

This method can be used for different UO2 powder types including grains, granules, spheres or other kinds of particles. The method can also be applied to other fuel powders as PuO2, ThO2 and powder mixtures as UO2-PuO2 and UO2-Gd2O3.

This International Standard is based on the principle of using a flowmeter funnel (4.1). Other measurement methods, such as a Scott volumeter, can also be used.

This International Standard specifies a procedure, in the field of ionizing radiation metrology, for the calculation of the “decision threshold”, the “detection limit” and the “limits of the coverage interval” for a non-negative ionizing radiation measurand when counting measurements with reselection of time or counts are carried out. The measurand results from a gross count rate and a background count rate as well as from further quantities on the basis of a model of the evaluation. In particular, the measurand can be the net count rate as the difference of the gross count rate and the background count rate, or the net activity of a sample. It can also be influenced by calibration of the measuring system, by sample treatment and by other factors.

This International Standard has been divided into four parts covering elementary applications in Part 1, advanced applications on the basis of the GUM Suppl. 1 in Part 2, applications to unfolding methods in Part 3, and guidance to the application in Part 4.

Part 1 covers basic applications of counting measurements frequently used in the field of ionizing radiation metrology. It is restricted to applications for which the uncertainties can be evaluated on the basis of the GUM (JCGM 2008). In Annex A the special case of repeated counting measurements with random influences and in Annex B measurements with linear analogous ratemeters are covered.

Part 2 extends the former ISO 11929:2010 to the evaluation of measurement uncertainties according to the GUM Supplement 1. Part 2 also presents some explanatory notes regarding general aspects of counting measurements and on Bayesian statistics in measurements.

Part 3 deals with the evaluation of measurements using unfolding methods and counting spectrometric multi-channel measurements if evaluated by unfolding methods, in particular, alpha- and gamma-spectrometric measurements. Further, it provides some advice how to deal with correlations and covariances.

Part 4 gives guidance to the application of this International Standard, summarizing shortly the general procedure and then presenting a wide range of numerical examples.

This International Standard also applies analogously to other measurements of any kind especially if a similar model of the evaluation is involved. Further practical examples can be found in other International Standards, for example ISO 18589 [6], ISO 9696 [7], ISO 9697 [8], ISO 9698 [9], ISO 10703

[10], ISO 7503 [11], ISO 28218 [12], and ISO 11885 [13].

This part of this European Standard specifies requirements for fire resisting data cabinets and diskette inserts.

Two methods of test are specified to determine the ability of fire resisting data cabinets to protect temperature and humidity sensitive contents from the effects of fire: a fire endurance test and a fire shock and impact test. Two levels of fire severity (S 60 and S 120) based upon time of fire exposure; and three protection classes (P, D and DIS) are specified using the maximum temperature increases and humidity values permitted within the storage space of the data cabinet.

Diskette inserts (DI 60 P/DIS and DI 120 P/DIS) are installed in data cabinets of protection class S 60 P or S 120 P, respectively, and subjected to a fire endurance test (see 5.1.2).

Requirements are also specified for test specimens, the technical documentation for the test specimen, correlation of the test specimen with the technical documentation, preparation for type testing and test procedures.

A scheme to classify the fire resisting data cabinets and diskette inserts from the test results is also given (see Table 1).

Diskette inserts should only be installed in data cabinets having the same design as the series of protection class S 60 P and S 120 P, respectively, in which the insert has been tested in accordance with 5.1.2. Where several inserts are installed, they should be built in one beside the other or one above the other from bottom to top, respectively. The volume and total height of the installed inserts should not exceed 50 % of the total internal volume or 50 % of the internal height, respectively, of the data cabinets into which they are installed. The dimensions of the insert can be adapted by increasing the width and depth to the corresponding dimensions of the data cabinets. A reduction of these dimensions as well as a change of the height is only admitted within the specified tolerance.

This part of the European Standard EN 1047 specifies requirements for data rooms and data containers. It includes a method of test for the determination of the ability of data rooms and data containers to protect temperature and humidity sensitive data media (see 3.5) and hardware systems (see 3.6) from the effects of fire. A test method for measuring the resistance to mechanical stress (impact test) provided by data rooms type B and data containers is also specified.

Requirements are also specified for test specimens, the technical documentation of the test specimens, materials specimens, physical fittings, the correlation of test specimens with the technical documentation and the preparation for type testing, as test procedures as well as the series production.

In addition, a scheme to classify data rooms and data containers from the test results is given (see Table 1).

As well as providing protection against fire, correctly installed data rooms and data containers offer a defined protection against impacts caused by failure during fire of components and objects external to the data room or data container.

Data rooms and data containers having the same design, protection and construction features (type and thickness of construction and protective materials, rebate geometry, lockings, doors, etc.) will only be given the same protection classification as that of the test specimen if the tolerances are within the ranges specified in Clause 7.

NOTE This European Standard does not regulate the use of data rooms in the meaning of the building laws of the respective countries. In the construction of data rooms, it is advised to consider the respective national requirements.

This document specifies the determination of the biochemical oxygen demand of waters by dilution and seeding with suppression of nitrification after 5 d incubation time.

It is applicable to all waters having biochemical oxygen demands usually between 3 mg/l and 6 000 mg/l. It applies particularly to waste waters. For biochemical oxygen demands greater than 6 000 mg/l of oxygen, the method is still applicable, but the errors caused by the necessary dilutions can influence the analytical quality of the test method. Then the results are to be interpreted with circumspection.

The results obtained are the product of a combination of biochemical and chemical reactions with participation by living matter which behaves only with occasional reproducibility. They do not have the rigorous and unambiguous character of those resulting from, for example, a single, well-defined,  chemical process. Nevertheless, they provide an indication from which the quality of waters can be estimated.

NOTE A limit of detection, as clearly defined in statistics, cannot be determined for this method.

The lower limit of the working range results from the limit conditions which are explained in 10.1 ("consumption rule") and in Table 1.

Annex A describes the method for an incubation time of 7 d.

Annex B describes multitesting, which can be used to obtain enhanced precision or to demonstrate the presence of substances toxic to microorganisms.

Annex C describes a seeding method in which the seeding is performed directly when applying the analysis approach.

Annex D provides performance data.

invertebrates and plants) to the species level, based on the DNA barcoding technique. This protocol can be used by laboratories performing DNA barcoding in order to standardise both the wet-lab and data analysis workflows as much as possible, and make them compliant with community standards and guidelines.

It is not intended by this International Standard to specify one particular strain for each test method, but to accurately document the species/strain which was used.

NOTE 1 This does not imply that DNA barcoding is performed in parallel to each test run, but rather regularly (e. g., once a year, such as reference substance testing) and each time a new culture is started or new individuals are added to an ongoing culture.

This International Standard does not aim at duplicating or replacing morphological-based species identifications. On the contrary, DNA barcoding is proposed as a complementary identification tool where morphology is inconclusive, or to diagnose cryptic species, in order to ensure that the results obtained from different ecotoxicological laboratories are referring to the same species or strain.

This International Standard is applicable to identifications of immature forms which lack morphological diagnostic characters (eggs, larvae, juveniles), as well as the streamline identification of specimens collected in field monitoring studies, where large numbers of organisms from diverse taxa are classified.

NOTE 2 In principle, all species regularly used in ecotoxicological testing can be analysed by DNA barcoding. Besides the earthwoms Eisenia fetida and E. andrei, further examples for terrestrial species are Lumbricus terrestris, L. rubellus, Allolobophora chlorotica, Aporrectodea rosea and A. caliginosa, Enchytraeus albidus and E. crypticus (Haplotaxida); Folsomia candida, F. fimetaria and Sinella curviseta (Collembola); Hypoaspis aculeifer and Oppia nitens (Acari); Aleochara bilineata and Poecilus cupreus (Coleoptera); Scathophaga stercoraria, Musca autumnalis (Diptera) or Pardosa sp. (Arachnida). Also nematodes or snails and even plants can be added to this list.

NOTE 3 The efficiency of DNA barcoding depends on the availability of reliable and taxonomically-comprehensive databases reference databases for comparison. International databases, such as GenBank or the Barcode of Life Data Systems (BOLD), allow access to all public DNA barcode sequence data.

NOTE 4 However, some of the species regularly used in ecotoxicological testing (e.g., Enchytraeus crypticus or Sinella curviseta) are poorly represented or even absent from those reference databases. In these cases, DNA barcoding can be heavily biased by Type II errors (misidentifications of queries without conspecific in the database) and therefore, species-level identifications should be confirmed by qualified taxonomists.

This document specifies a chronic test method for evaluating the habitat function of soils and determining effects of soil contaminants and substances on the reproduction of Hypoaspis aculeifer by – mainly – alimentary uptake. This chronic test is applicable to soils and soil materials of unknown quality, e. g. from contaminated sites, amended soils, soils after remediation, industrial, agricultural or other sites under concern and waste materials (e. g. dredged material, municipal sludge from a wastewater treatment plant, composed material, or manure, especially those for possible land disposal). The test reflects the bioavailability of a mixture of contaminants in natural soils (contaminated site soils) to a species which represents a trophic level which is so far not covered by ISO. The reproduction (= number of juveniles) is the measured parameter of the test. It is not intended to use this test to replace the earthworm (ISO 11268-2) or Collembola reproduction tests (ISO 11267) since this species belongs not only to another trophic group but also to another taxonomic group (= mites; i.e. arachnids) than the other test species used so far.

Effects of substances are assessed using a standard soil, preferably a defined artificial soil substrate. For contaminated soils, the effects are determined in the soil to be tested and in a control soil. According to the objective of the study, the control and dilution substrate (dilution series of contaminated soil) are either an uncontaminated soil comparable to the soil to be tested (reference soil) or a standard soil (e. g. artificial soil).

This document provides information how to use this method for testing substances under temperate conditions.

This document is not applicable to substances for which the air/soil partition coefficient is greater than one, or to substances with vapour pressure exceeding 300 Pa at 25°C.

NOTE The stability of the test substance cannot be assured over the test period. No provision is made in the test method for monitoring the persistence of the substance under test.

This part of ISO 16000 specifies a general laboratory test method for evaluating the reduction of formaldehyde and other carbonyl compounds (aldehydes and ketones) concentrations by sorptive building materials. This method applies to boards, wallpapers, carpets, paint products, and other building materials. The sorption of those target compound(s), i.e. formaldehyde and other carbonyl compounds can be brought about by adsorption, absorption and chemisorption. The performance of the material with respect to its ability to reduce the concentration of formaldehyde and other carbonyl compounds in indoor air is evaluated by measuring area specific reduction rate and saturation mass per area. The former directly indicates material performance with respect to formaldehyde and other carbonyl compounds concentration reduction at a point in time; the latter relates to the ability of a product to maintain that performance.

The method specified in this part of ISO 16000 employs formaldehyde and other carbonyl compounds -spiked supply air to determine the performance of building materials in reducing formaldehyde and other carbonyl compounds concentrations.

This part of ISO 16000 is based on the test chamber method specified in ISO 16000-9. Sampling, transport and storage of materials to be tested and preparation of test specimens are specified in ISO 16000-11. Air sampling and analytical methods for the determination of formaldehyde and other carbonyl compounds are specified in ISO 16000-3, which is part of the complete procedure.

This part of ISO 16000 applies to the determination of formaldehyde and other carbonyl compounds, e.g., formaldehyde; acetaldehyde; acetone; benzaldehyde; butyraldehyde; valeraldehyde; 2,5-dimethylbenzaldehyde; capronaldehyde; isovaleraldehyde; propionaldehyde; o-tolualdehyde; m-tolualdehyde; p-tolualdehyde.
