This document specifies conditions for the determination of 90Sr and 89Sr activity concentration in samples of environmental water using liquid scintillation counting (LSC) or proportional counting (PC).
The method is applicable to test samples of drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. Filtration of the test sample and a chemical separation are required to separate and purify strontium from a test portion of the sample.
The detection limit depends on the sample volume, the instrument used, the sample count time, the background count rate, the detection efficiency and the chemical yield. The method described in this document, using currently available LSC counters, has a detection limit of approximately 10 mBq l−1 and 2 mBq l−1 for 89Sr and 90Sr, respectively, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l−1 for 89Sr and 10 Bq·l−1 for 90Sr)[3]. These values can be achieved with a counting time of 1 000 min for a sample volume of 2 l.
The methods described in this document are applicable in the event of an emergency situation. When fallout occurs following a nuclear accident, the contribution of 89Sr to the total amount of radioactive strontium is not negligible. This document provides test methods to determine the activity concentration of 90Sr in presence of 89Sr.
The analysis of 90Sr and 89Sr adsorbed to suspended matter is not covered by this method.
It is the user’s responsibility to ensure the validity of this test method selected for the water samples tested.

This document specifies a method for the enumeration of the characteristic microorganisms Lactobacillus delbrueckii subsp. bulgaricus (in short: L. bulgaricus) and Streptococcus thermophilus (in short: S. thermophilus) by means of the colony-count technique.
The method is applicable to yoghurts (for the definition see CXS 243‑2003).
The colony-count technique (pour plates) is suitable for, but not limited to, the enumeration of L. bulgaricus and S. thermophilus in test samples with a minimum of 10 colonies counted on a plate. This corresponds to a level of the characteristic microorganisms L. bulgaricus and S. thermophilus that is expected to be higher than 100 cfu/g.
The colony-count technique (spread plates) is suitable for, but not limited to, the enumeration of L. bulgaricus and S. thermophilus in test samples with a minimum of 10 colonies counted on a plate. This corresponds to a level of the characteristic microorganisms L. bulgaricus and S. thermophilus that is expected to be higher than 1 000 cfu/g.

1.1 This International Standard contains principles and requirements for the competence, consistency and impartiality of the certification of products (including services; see clause 3.3 of ISO/IEC 17000) and processes and for the bodies providing those activities. Certification bodies operating to this International Standard need not offer all types of product, service or process certification.
1.2 Certification of products, services and processes is a third party conformity assessment activity (see clause 5.5 of ISO/IEC 17000:2004). Bodies performing this activity are therefore third party conformity assessment bodies, (named in this standard "certification body/bodies").
Note 1 A certification body can be non-governmental or governmental (with or without regulatory authority).
Note 2 This International Standard can be used as a criteria document for accreditation or peer assessment or other assessment processes.

This document describes two equivalent test methods for determining the glass content in Granulated blast furnace Slag (GBS) as constituent for common cement as defined on EN 197-1.
Method A - Method of determining the glass content of GBS by X-ray diffraction.
Method B - Method of determining the glass content of GBS by polarized optical microscopy.
The glass content (or glassy/amorphous phase) in GBS is the fraction of the material that lacks a crystalline structure, having solidified rapidly from the melt in the form of amorphous glass.
It is usually expressed as a percentage (wt%) of the total slag.
In the absence of a product standard or a specification in the product standard, the constituent is tested at the fineness of the intended use.
Furthermore, these test methods are used in manufacturing control of cement constituents for assessing their conformity to the limit indicated in EN 197-1.

This document describes a method for the determination of whiteness and the colour of common cements and clinkers.
This method can be used to determine the whiteness of white cements defined in the EN 197-1.
This document does not apply to colour measurements on cement-based formulated products or cement-based products.
The method is based on the measurement of the CIE XYZ trichromatic coordinates and describes the mathematical procedure for converting these coordinates into the CIE 1976 (L*a*b*) colour space.
NOTE Although the possible values of the L* parameter range from 0 to 100, this document applies to the range between 70 and 100 (photopic vision).

This document describes the method for determining the contribution of cement’s alkali to the alkali-silica reaction process that can occur in concrete or mortar containing aggregates potentially susceptible to alkali attack.
The principle is to consider the alkalis from the insoluble part of the cement (generally associated with fly ash, for example, or pozzolans) and the alkali from the diluted part of the cement (generally associated with clinker, gypsum, granulated blast furnace slag, or limestone) [1].
This test method can be used in the framework of preventing the risk of alkali silica reaction [2].
