This document specifies requirements, including corrosion protection, for the design, fabrication, installation and maintenance of steel-cased pipelines for pipeline transportation systems in the petroleum and natural gas industries in accordance with ISO 13623. NOTE 1 Steel casings can be used for mechanical protection of pipelines at crossings, such as at roads and railways and the installation of a casing at a highway, railway, or other crossing can be required by the permitting agency or pipeline operator. NOTE 2 This document does not imply that utilization of casings is mandatory or necessary. NOTE 3 This document does not imply that cased crossings, whether electrically isolated or electrically shorted, contribute to corrosion of a carrier pipe within a cased crossing. However, cased crossings can adversely affect the integrity of the carrier pipe by shielding cathodic protection (CP) current to the carrier pipe or reducing the CP effectiveness on the carrier pipe in the vicinity of the casing. Their use is not recommended unless required by load considerations, unstable soil conditions, or when their use is dictated by sound engineering practices.
This document specifies a method of testing uniaxially deformed specimens under strain control at constant amplitude, uniform temperature and fixed strain ratios including at Re = −1 for the determination of material fatigue properties. It can also be used as a guide for testing under other R-ratios, as well as elevated temperatures where creep deformation effects may be active.
This document specifies the methods for the chemical analysis of fine silicon nitride powders used as the raw material for fine ceramics. It stipulates the determination methods of total silicon, total nitrogen, aluminium, iron, calcium, oxygen, carbon, fluorine, and chlorine in fine silicon nitride powders.
This document provides an overview of relevant methods for the determination of specific parameters in solid soil improvers, including: — dry matter content; — quantity; — copper and zinc content; — chloride content; — nitrogen content; — P2O5 (phosphorus pentoxide) and K2O (potassium oxide) content. This document is applicable to the fertilizing product blends where a blend is a mix of two or more fertilising products belonging to the categories of fertilizers, liming material, soil improvers, growing media, inhibitors and plant biostimulants, and where soil improvers and/or growing media are the components with the highest percentage in the blend by mass or volume, or in the case of products in liquid form by dry mass. If the soil improvers and/or growing media are not the components with the highest percentage in the blend, the European Standard relevant to the component with the highest percentage in the blend applies. In case a blend is composed of fertilising products mixed in equal quantities, the user of the standard decides which standard to apply. NOTE A soil improver consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite).
This document specifies a method for the extraction of water-soluble calcium, magnesium, sodium and sulfur (in the form of sulfates), so that the same extract can be used for the determination of each nutrient required. This document is applicable to inorganic fertilizers.
This document specifies a method for the extraction of phosphorus soluble in neutral ammonium citrate in inorganic fertilizers.

This document specifies a method for the extraction of phosphorus soluble in mineral acids in inorganic fertilizers.
This document specifies a method applicable to inorganic fertilizers for the extraction with diluted mineral acid of total calcium, total magnesium and total sodium and for the extraction of total sulfur present in the form of sulfates, so that the same extract may be used for the determination of each nutrient required.
This document specifies the procedure for extraction of different organic and organo-mineral fertilizers with water to enable a subsequent determination of boron (B), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), phosphorous (P) and zinc (Zn). NOTE Extracts prepared by the procedure given in this document can also be applied for determination of other elements. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

ISO 8442-5:2004 specifies the sharpness and edge retention of knives which are produced for professional and domestic use in the preparation of food of all kinds, specifically those knives intended for hand use. Powered blade instruments of any kind are excluded. Generally these types of knife are manufactured with blades of either plain edge design or with edges incorporating particular features to enhance or optimize aspects of cutting ability. The following two types of knife blade are suitable for the cutting test. Type A edges: cutting edges which can be resharpened by the user and edges with a pitch greater than 1mm; Type B edges: cutting edges which are not intended to be resharpened on a steel. Whilst these knives are predominantly manufactured with blades made from various grades of heat treated steels, the testing of knives of any construction or blade material is not precluded providing that the test criteria are met. The principle of the testing is to reproduce a cutting action, by forward and reverse strokes, against a pack of synthetic test medium under controlled parameters.

This document specifies fundamental techniques of film and digital radiography with the object of enabling satisfactory and repeatable results to be obtained economically. The techniques are based on generally recognized practice and fundamental theory of the subject. This document applies to the radiographic examination of pipes in metallic materials for service induced flaws such as corrosion pitting, generalized corrosion and erosion. Besides its conventional meaning, "pipe" as used in this document is understood to cover other cylindrical bodies such as tubes, penstocks, boiler drums and pressure vessels. Weld inspection for typical welding process induced flaws is not covered, but weld inspection is included for corrosion/erosion type flaws. The pipes can be insulated or not, and can be assessed where loss of material due, for example, to corrosion or erosion is suspected either internally or externally. This document covers double wall inspection techniques for detection of wall loss, including double wall single image (DWSI) and double wall double image (DWDI). Note that the DWDI technique described in this document is often combined with the tangential technique covered in ISO 20769-1. This document applies to in-service double wall radiographic inspection using industrial radiographic film techniques, computed digital radiography (CR) and digital detector arrays (DDA).

This document covers the tangential inspection technique for detection and through-wall sizing of wall loss, including with the source: a) on the pipe centre line; and b) offset from pipe centre line by the pipe radius. ISO 20769-2 covers double wall radiography, and note that the double wall double image technique is often combined with tangential radiography with the source on the pipe centre line. This document applies to tangential radiographic inspection using industrial radiographic film techniques, computed radiography (CR) and digital detector arrays (DDA).
This document describes a method for the ultrasonic testing of uncoated flat steel product for internal discontinuities. This document is applicable to flat product in nominal thickness range of 5 mm to 200 mm of non-alloyed or alloyed steel, excluding austenitic or austenoferritic steels. However, this document can be applied to the latter types of steels provided that the difference between the amplitude of the noise signal and that of the echo detection threshold is sufficient for the limit fixed. This document also defines five quality classes for the flat product body (classes S0, S1, SA, S2 and S3) and five classes (E0, E1, E2, E3, E4) for the edges (see Clause 13). Other methods of testing (e.g. by phased-array) or other test equipment may be used at the manufacturer's discretion provided that they give identical results to those obtained under the conditions of this document. In the event of a dispute, only the method defined in this document shall prevail. Testing of flat product of thickness less than 5 mm or higher than 200 mm may be the subject of special agreements between the parties concerned. The inspection is normally carried out in the place of production or on the premises of the supplier. If specified on the order, the inspection takes place in the presence of the purchaser or his representative1. A list of equivalent terms in several European languages is given in Annex A.
