This document specifies a method for the determination of the residual biogas potential in digestate in an anaerobic environment.

ISO 17228:2015 specifies various ageing procedures to obtain an indication of the changes that could occur when leather is exposed to a certain environment for a prolonged time. Over time, the surface colour of leather and the leather itself change due to ageing and to the action of the surroundings on the leather. The test conditions to be used depend on the type of leather and its intended use.
This procedure can also be used to age specimens for the test of dimensional change according to ISO 17130.

This document specifies a method for determining the resistance of all forms of leather to visible soiling through repeated contact with soiled objects. It provides a physical pretreatment routine for leathers that may be vulnerable to loss of soiling resistance while in service, prior to conducting further tests such as cleaning.

ISO 16634-2:2016 specifies a method for the determination of the total nitrogen content and the calculation of the crude protein content of cereals, pulses and milled cereal products.
This method, like the Kjeldahl method (see References [1] and [6]), does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of the protein content, various conversion factors are used (see 3.2).

(SCG) of polyethylene materials, pipes, and fittings. The test is applicable to samples taken from 
compression moulded sheet or extruded pipes and injection moulded fittings of suitable thickness.
This International Standard provides a method that is suitable for an accelerated fracture-mechanics 
characterization at ambient temperatures of 23 °C of different polyethylene grades, especially for PE 
80 and PE 100 types for pipe applications.

The intent of ISO 10318-2:2015 is to define property symbols, graphical symbols, and pictograms used in EN and ISO geosynthetics standards. Definitions of particular or specific symbols and pictograms terms not included in this this part of ISO 10318 can be found in the International Standards describing appropriate test methods.

This International Standard describes the procedure to qualitatively detect genetically modified organisms
(GMOs) and derived products by analysing the nucleic acids extracted from the sample under study. The main
focus is on polymerase chain reaction (PCR) based amplification methods.
It gives general requirements for the specific detection and identification of target nucleic acid sequences
(DNA) and for the confirmation of the identity of the amplified DNA sequence.
Guidelines, minimum requirements and performance criteria laid down in this International Standard are
intended to ensure that comparable, accurate and reproducible results are obtained in different laboratories.
This International Standard has been established for food matrices, but could also be applied to other
matrices (e.g. feed and plant samples from the environment).
Specific examples of methods are provided in Annexes A to D.

This document provides the design, construction and test requirement for the structures of monorail beams and pad eyes intended for material handling of the both onshore and offshore oil and gas projects.
This document is based on major international standards to comply with requirements of shelf regulations of UK, US, Norway and Australia. Overall the requirements outlined in this document should meet most of the specified regulatory requirements. Exemptions where requirements in common standards are not met in this document are clearly stated.The standard shapes, dimensions and material grades are defined in this document.

This part of ISO 14577 specifies the method of dynamic linear elastic instrumented indentation test
for determination of indentation hardness and indentation modulus of materials showing elasticplastic
behaviour when oscillatory force or displacement is applied to the indenter while the load or
displacement is held constant at a prescribed target value or while the indenter is continuously loaded
to a prescribed target load or target depth.

ISO 8536-5:2004 specifies requirements for types of single-use, gravity feed burette infusion sets of 50 ml, 100 ml and 150 ml nominal capacity for medical use in order to ensure compatibility of use with containers for infusion solutions and intravenous equipment.
ISO 8536-5:2004 also provides guidance on specifications relating to the quality and performance of materials.
In some countries, national pharmacopoeia or other national regulations are legally binding and take precedence over ISO 8536-5:2004.

This document specifies the dimensions, linear resistance, mechanical characteristics, construction and mass of lightweight conductors, normal and tight tolerances, in copper or copper alloy for electrical cables for aerospace applications.
It applies to stranded conductors, with a nominal cross-sectional area of 0,15 mm2 to 14 mm2 inclusive.
The conductors for thermocouple extension and fire-resistant cables are not covered by this document.

This document specifies principles and testing procedures for determining, by means of the guarded hot plate or heat flow meter methods, the thermal resistance of test specimens either in the dry state or conditioned to equilibrium with moist air, having a thermal resistance of not less than 0,1 m2·K/W and a (hygro)thermal transmissivity or thermal conductivity up to 2,0 W/(m·K).
NOTE   The lower limit for measurable thermal resistance is due to the effect of contact thermal resistances, which require special testing techniques described in this document. Although this document can be used for testing dry specimens of high and medium thermal resistance, i.e. on products having a thermal resistance, that is, on products with a thermal resistance of at least 0.5 m².K/W, the simpler procedures of EN 12667[3] are available for such specimen.
This document does not cover methods to assess the hygrothermal transmissivity of materials in the over-hygroscopic range (i.e. when free liquid water occurs in the material in general above 95% of moisture).
It applies in principle to any mean test temperature, but the equipment design in Annex D is essentially intended to operate between a minimum cooling unit temperature of -100 °C and maximum heating unit temperature of +100 °C.
This document does not supply general guidance and background information (e.g. the heat transfer property to be reported, product-dependent specimen preparations, suggested materials for vapour-tight envelopes when testing moist specimens, procedures requiring multiple measurements, such as those to assess the effect of specimen non-homogeneities, those to test specimens whose thickness exceeds the apparatus capabilities, and those to assess the relevance of the thickness effect).

This document specifies principles and testing procedures for determining, by means of the guarded hot plate or heat flow meter methods, the thermal resistance of dry test specimens having a thermal resistance of not less than 0,5 m2·K/W.
NOTE 1  The above limit is due to the effect of contact thermal resistances. An upper limit for measurable thermal resistance depends upon a number of factors described in this document, but a unique figure cannot be assigned.
It applies in principle to any mean test temperature, but the equipment design in Annex D is essentially intended to operate between a minimum cooling unit temperature of -100 °C and maximum heating unit temperature of +100 °C.
NOTE 2   Limits to the mean test temperature are only imposed by the materials used in the apparatus construction and by ancillary equipment.
This document does not supply general guidance and background information (e.g. the heat transfer property to be reported, product-dependent specimen preparations, procedures requiring multiple measurements, such as those to assess the effect of specimen non-homogeneities, those to test specimens whose thickness exceeds the apparatus capabilities, and those to assess the relevance of the thickness effect).
This document does not apply to cover measurements on moist products of any thermal resistance or measurements on thick products of high and medium thermal resistance.

This document specifies procedures to determine the thermal resistance of products whose thicknesses exceed the maximum thickness for guarded hot plate or heat flow meter apparatus. Most of the procedures described in this standard require apparatus that allows tests on specimens up to 100 mm thick .
This document gives guidelines to assess the relevance of the thickness effect, i.e. to establish whether the thermal resistance of a thick product can or cannot be calculated as the sum of the thermal resistances of slices cut from the product, these guidelines complement the indications given in ISO 8302:1991[1] on the guarded hot plate apparatus.
This document describes testing conditions which prevent the onset of convection which could take place in some products under the considered temperature differences and thicknesses.
