Methods of testing cement - Part 10: Determination of the water-soluble chromium (VI) content of cement

This document specifies the method for the determination of the water-soluble chromium (VI) content of cement. A reference method is described consisting of two stages, an extraction procedure and an analysis of the filtered extract. Guidance on other extraction procedures, suitable for screening tests, for factory production control or other purposes, is given but in case of dispute or failure to comply with a regulatory limit only the reference method is used. The reference method has alternatives whereby the filtered extract can be subjected to an oxidation step or not. The criteria by which the appropriate procedure is selected are set down. Other instrumental procedures can be used for the analysis of the filtered extract provided they are calibrated against the analysis of the filtered extract using the reference procedure. In the case of a dispute, only the reference method is used. This document specifies, for the determination of water-soluble chromium (VI) in the filtered extract, the reference methods (colorimetric determination by diphenylcarbazide in acidic conditions) and another method for the determination of total water-soluble chromium (by inductively coupled plasma optical emission spectroscopy, ICP-OES). The ICP-OES determines the total chromium content independently of the chemical species, i.e. whether it is present as chromium (III) or chromium (VI), for example. Experience has demonstrated that soluble chromium (VI) is predominantly present during the processing phase, such that, in most cases, the determination of total water-soluble chromium effectively reflects the chromium (VI) content. The water-soluble chromium (VI) content of cement can therefore be assessed conservatively using the method based on ICP-OES described in this document. In the case of a dispute, only the reference methods are used. This document specifies a method that applies to cements. NOTE 1 Annex A provides guidance on the possible application of this document to the determination of the water-soluble chromium (VI) content of cement-containing preparations. NOTE 2 Annexes B and C provide information on other test procedures based on paste extraction and thus depart from the performance of cement in its normal conditions of use. They can be carried out with or without the oxidation process. It is important that users are aware that results using these methods might be significantly different to those obtained by the reference method. In the case of dispute or failure to comply with the regulatory limit, only the reference method is used. NOTE 3 Annex D provides guidance on a method for determination of the excess reducing agent content of cement as used in the factory internal control system of some countries. It is important that manufacturers using such an internal control method ensure themselves of the relevance of results in comparison with testing by the reference method.

Building valves - Combined temperature and pressure relief valves - Tests and requirements

This document specifies dimensions, materials and performance requirements, including test methods, for combined temperature and pressure relief valves, of nominal sizes from DN 15 to DN 40, having working pressures ) from 0,3 MPa (3 bar) to 1,0 MPa (10 bar). Combined temperature and pressure relief valves control and limit the temperature and pressure of the water contained in a hot water heater to the valves rating pressure and a temperature not exceeding 100 °C and will prevent water to steam formation when other temperature controls fail. Combined temperature and pressure relief valves are classified having a maximum opening temperature range from 90 °C to 95 °C for class A and 75 °C to 80 °C for class B. They are not intended to act as an expansion valve and do not control cold water flow. Alone it does not constitute the control functions for a water heater. A combined temperature and pressure relief valve is an independently mechanically operating device, therefore operating without an external energy source. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information, see Annex B).

Horizontal methods for molecular biomarker analysis - Methods of analysis for the detection of genetically modified organisms and derived products - Part 1: Qualitative nucleic acid based methods (ISO/DIS 21569-1:2025)

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.

Water quality - Gross beta activity - Test method using thick source (ISO/DIS 9697:2025)

This document specifies a test method for the determination of gross beta activity concentration in nonsaline waters. The method covers non-volatile radionuclides with maximum beta energies of approximately 0,3 MeV or higher. Measurement of low-energy beta emitters (e.g. 3H, 228Ra, 210Pb, 14C, 35S and 241Pu) and some gaseous or volatile radionuclides (e.g. radon and radioiodine) are not be included in the gross beta quantification using the test method described in this document. This test method is applicable to the analysis of raw and drinking waters with low amounts of total soluble salts in the water. Limit of detection depends on the performance characteristics (background count rate and counting efficiency) of the counter used. It is the laboratory’s responsibility to ensure the suitability of this method for the water samples tested. As this method requires sample preparation in laboratory facilities, it is not suited for rapid, in-the-field analysis.
