This document specifies a laboratory test method to determine the degree and rate of aerobic biodegradation level of plastic materials. This test method can also be applied to other materials. Biodegradation is determined by measuring the CO2 evolved by the plastic material when exposed to marine sediments sampled from a sandy tidal zone and kept wet with salt-water under laboratory conditions.…

This document specifies a method, using concentrated sulfuric acid, to determine the mass percentage of chlorofibres and certain other fibres, after removal of non-fibrous material, in textiles made of mixtures of — cotton, viscose, cupro, modal, lyocell, acetate, triacetate, polyamide, polyester, elastomultiester, certain acrylic and certain modacrylic fibres with — chlorofibres (based…

This document provides the principles and procedures of environmental management for maintenance/remedial activities of concrete structures, and environmental management during the operation of concrete structures. When the environmental design of a concrete structure is to be carried out based on ISO 13315‑4, this document provides detailed information on the design for its use stage.

Le présent document spécifie une méthode de détermination, à l'acide sulfurique concentré, de la masse exprimée en pourcentage de chlorofibres et de certaines autres fibres, après élimination des matières non fibreuses, dans les textiles composés de mélanges de: — coton, viscose, cupro, modal, lyocell, acétate, triacétate, polyamide, polyester, élastomultiester, certaines fibres…

Le présent document spécifie une méthode d’essai en laboratoire permettant de déterminer le taux et le niveau de biodégradation aérobie des matériaux plastiques. Cette méthode d’essai peut également être appliquée à d’autres matériaux. La biodégradation est déterminée en mesurant le CO2 libéré par le matériau plastique lorsqu’il est exposé à des sédiments marins prélevés dans une zone tidale…

This document provides a testing method for testing phenol oxidative decomposition performance of semiconducting photocatalytic materials or made of a material adsorbed with photocatalyst to its surface for the purpose of purifying water polluting substances in water making use of photocatalytic performance as test piece. The test piece can be planar, spherical, flake or block shape. A test piece…

This document provides the requirements for structural design and procedures following a semi-probabilistic approach that conform to the general principles for structural reliability as stipulated by ISO 2394. The scope of requirements and procedures are accordingly limited to the design of structures for which sufficient knowledge and experience are commonly available on design and construction…

This document outlines design evaluation guidelines for absorbable cardiovascular implants used to treat vessels and/or the vascular space within the circulatory system, including the heart and all vasculature. This document is meant to supplement device-specific standards by providing guidelines specific for absorbable implants and/or components This document is applicable to implants in direct…

This document specifies a test method for the determination of the biodegradability of the hydrolysate of textile materials obtained after accelerated hydrolysis under controlled composting conditions by measurement of the amount of evolved carbon dioxide with a gas chromatography. This test method can be applied to petroleum-based man-made biodegradable textile materials which are manufactured…
