ISO/ASTM 51607 covers materials description, dosimeter preparation, instrumentation and procedures for using the alanine-EPR dosimetry system for measuring the absorbed dose in materials irradiated with photons and electrons. The system is based on electron paramagnetic resonance (EPR) spectroscopy of free radicals derived from the amino acid alanine. It is classified as a reference standard…

This International Standard specifies a metadata system for describing multimedia content. It specifies the Description Definition Language (DDL) that comprises part 2 of the standard (ISO/IEC 15938-2).The goal of this part of the MPEG-7 International Standard is to specify a language that will enable MPEG-7 users and developers to:• create valid MPEG-7 description schemes and descriptors;•…

This International Standard specifies certain characteristics of the oil of neroli ( Citrus aurantium L. ssp. aurantium syn. Citrus aurantium L. ssp. amara var. pumilia), cultivated principally in Tunisia and Morocco, with a view to facilitate assessment of its quality.

This International Standard gives guidance on the selection and method of appropriate tests for the determination of biodegradation of organic chemicals in soil samples under anaerobic conditions. NOTE For methods intended for tests in the framework of the registration of chemicals, an OECD Guideline on soil degradation gives useful guidance on additional test requirements.

This International Standard describes a method with two procedures for the assessment of pigment or carbon black particle and agglomerate size and degree of dispersion in polyolefin pipes, fittings and compounds. The method is applicable to polyolefin pipes and fittings, as well as raw material in pellet form, with the choice of procedure to be determined by the referring specification. The…

This international Standard defines terms of the possible imperfections in oxyfuel gas, laser beam and plasma cuts in metallic materials which are collected and grouped. Imperfections are irregularities or deviations from the specified shape and location of cut. This international Standard only includes imperfections originating directly from oxyfuel gas, laser beam and plasma arc cutting; any…
