This document specifies characteristics of fresh and dry baker’s yeast, particularly those relating to general product properties, application performance, physical and chemical properties, microbiology, and nutritional value information. This document is primarily intended for use by the baking industry, but is also aimed at laboratory and food testers

This international standard is intended to provide a protocol for the interlab validation of methods for the characterization of sludge/biosolids physical properties considered that in most cases fresh sludge samples cannot be circulated to several laboratories in different countries for validation purposes as uncontrolled variations of their characteristics would occur.

This document specifies the general requirements for determining the equilibrium temperature of natural gas hydrate in the laboratory, and describes the test methods, instruments, materials and experimental data processing methods of the equilibrium temperature of natural gas hydrate under constant volume conditions.

This document defines a Universal Cybersecurity Labelling Framework for the development and implementation of cybersecurity labelling programmes for consumer IoT products and includes guidance on the following topics: • Risks and threats associated with consumer IoT products; • Stakeholders, roles and responsibilities; • Relevant standards and guidance documents; • Conformity assessment options…

ISO 19581 specifies a screening test method to quantify rapidly the activity concentration of gamma-emitting radionuclides, such as 131I, 132Te, 134Cs and 137Cs, in solid or liquid test samples using gamma-ray spectrometry with lower resolution scintillation detectors as compared with the HPGe detectors (see IEC 61563). This test method can be used for the measurement of any potentially…

This document specifies a method for the determination of gross alpha and gross beta activity concentration for alpha- and beta-emitting radionuclides. Gross alpha and gross beta activity measurement is not intended to give an absolute determination of the activity concentration of all alpha and beta emitting radionuclides in a test sample, but is a screening analysis to ensure particular…

This document specifies a laboratory test method for determining the aerobic biodegradability of fibres and textile materials in seawater by measuring the biochemical oxygen demand or the amount of carbon dioxide evolved. This method can be applied to fibres and textile materials (e.g. staples, tops, yarns and fabrics).

To develop a list of standardised core terms and definitions to be used by ISO/TC 336 Laboratory Design to enable a consistent and unambiguous understanding of the standard's requirements and its practical application.

This document specifies requirements and test methods for powered polymerization activators in the 380 nm to 515 nm wavelength region intended for chairside use in polymerization of dental polymer-based materials. This document applies to quartz-tungsten-halogen lamps and light-emitting diode (LED) lamps. Powered polymerization activators could have internal power supply (rechargeable battery…

The document specifies a method for the determation of the changes in colour of sealants after laboratory accelerated weathering procedures using artificial light sources.
