This document specifies a method for the correct measurement of the colour of finished leather by instrumental means. The document describes general concepts of colour measurement adapted to leather and the calculation of differences in colour.
This document defines the following:
a) the use of D65 as the standard light source for the leather industry;
b) the use of D65 light source 10° as standard conditions for colour matching, for the definition of daylight simulators and as the reference light source for metamerism analysis;
c) the use of CIEDE2000 as the colour difference formula.

This document specifies a test method for measuring the forces needed for the placement and removal of dental attachments (frictional retention elements of ball head-, snap-on, prefabricated telescopic and bar systems used for the attachment, support and stabilization of crowns and bridges, single attachments, removable partial dentures, complete dentures, and other superstructures on dental implant systems (including monopart implants)and, if not other justified, on natural teeth and root post copings). If not otherwise justified, this document can also be used for tests on custom-made or patient matched devices (e.g. laboratory manufactured). This test method is not applicable to retention devices for which normal placement and removal requires any off-axis rotation for the path of least resistance. This test method is not applicable to dental magnetic attachments, these are specified in ISO 13017.

ISO 10555-3:2013 specifies requirements for central venous catheters supplied in the sterile condition, and intended for single use.

ISO 10555-5:2013 specifies requirements for over-needle peripheral intravascular catheters, intended for accessing the peripheral vascular system, supplied in the sterile condition and intended for single use.

ISO 17186:2011 specifies a method for determining the thickness of the surface coating applied to leather when measured under zero compression. It is applicable to all types of leather.

ISO 27917:2017 defines a list of cross-cutting terms commonly used in the field of carbon dioxide capture, transportation and geological sub-surface storage including through storage in association with enhanced oil recovery (EOR) operations.
ISO 27917:2017 only deals with CO2 geological sub-surface storage.
The terms are classified as follows:
- general terms and definitions relating to carbon dioxide;
- general terms and definitions relating to carbon dioxide capture, transportation and storage;
- general terms and definitions relating to monitoring and measuring performance in carbon dioxide capture, transportation and geological storage;
- general terms and definitions relating to risk;
- general terms and definitions relating to relationships with stakeholders;
A list of the main acronyms used is given in Annex A.

This document applies to uniaxial strain-controlled low cycle fatigue testing of metallic materials governed by EN aerospace standards. It defines the properties that need to be determined and the terms used in describing the tests and test pieces.
It specifies the equipment, the test pieces, the method of testing and the presentation of results. It applies to testing at ambient and elevated temperatures.
The purpose of this document is to ensure the comparability and reproducibility of the test results. It does not cover the evaluation or interpretation of the results.
This document is restricted to the use of test pieces having a circular cross-section. In some particular cases the practice can be applied to flat test pieces. The major difficulties concern the preparation of the test pieces and their alignment in the grips.

This document specifies requirements for chemical and physical properties of natural pozzolana and natural activated pozzolanic material for use as addition to concrete, and for use in mortar and grouts.
It also specifies requirements for conformity criteria.

This document specifies methods used to determine the concentration of plutonium and neptunium isotopes in water by inductively coupled plasma mass spectrometry (ICP-MS) (239Pu, 240Pu, 241Pu and 237Np). The concentrations obtained can be converted into activity concentrations of the different isotopes[9].
Due to its relatively short half-life and 238U isobaric interference, 238Pu can hardly be measured by this method. To quantify this isotope, other techniques can be used (ICP-MS with collision-reaction cell, ICP-MS/MS with collision-reaction cell or chemical separation). Alpha spectrometry measurement, as described in ISO 13167[10], is currently used[11].
This method is applicable to all types of water having a saline load less than 1 g·l−1. A dilution of the sample is possible to obtain a solution having a saline load and activity concentrations compatible with the preparation and the measurement assembly.
A filtration at 0,45 μm is needed for determination of dissolved nuclides. Acidification and chemical separation of the sample are always needed.
The limit of quantification depends on the chemical separation and the performance of the measurement device.
This method covers the measurement of those isotopes in water in activity concentrations between around[12][13]:
— 1 mBq·l−1 to 5 Bq·l−1 for 239Pu, 240Pu and 237Np;
— 1 Bq·l−1 to 5 Bq·l−1 for 241Pu.
In both cases, samples with higher activity concentrations than 5 Bq·l−1 can be measured if a dilution is performed before the chemical separation.
It is possible to measure 241Pu following a pre-concentration step of at least 1 000.

This document specifies general requirements and test methods for endodontic instruments used for endodontic purposes, e.g. enlargers, compactors, accessory instruments, shaping and cleaning instruments, and a numeric coding system. In addition, it covers general size designations, color-coding, packaging, and identification symbols.

This document specifies a method for the determination of the content of total nitrogen in urea, methylene-urea and urea formaldehyde in their pure form in inorganic fertilizers.

This document specifies a method for the determination of the cold and hot water insoluble nitrogen content in solid urea formaldehyde and methylene urea slow-release fertilizers and for the determination of the solubility of nutrient polymers in a phosphate buffer solution with a pH of 7,5 at 100 °C, in their pure form in inorganic fertilizers.
This document is not applicable to the following nutrient polymers: liquid methylene urea.
