This document specifies the general aspects of impact resistant unplasticized poly(vinyl chloride) (PVC-HI) solid wall piping systems intended for water supply and for buried and above-ground drainage and sewerage under pressure. In conjunction with ISO 1452-1, 1452-2 and 1452-3, it is applicable to PVC-HI pipes, fittings, valves and ancillary equipment, their joints and to joints with…

ISO 9849:2017 defines terms relating to geodetic field instruments only, e.g. distance meters, levels, theodolites and others, and their essential component parts which are normally used in terrestrial measuring operations of ordnance survey, topographic survey, plane survey and engineering survey. Therefore, terms concerning fields such as the following are not mentioned, for example,…

This document provides basic regulations for adsorption efficiency testing methods using radioactive methyl iodine in activated carbon fibres used to adsorb and remove radioactive isotopes (I131) contained in air or gas flow (exhaust). This test method is used to evaluate the adsorption efficiency of radioactive isotopes leaked from nuclear facilities, hospitals, and companies handling…

This [proposed] standard is for anybody who creates or helps create scientific documents intended for diverse audiences. It builds, and relies, on the foundation for plain language in ISO/DIS 24495-1, Plain Language — Part 1: Governing Principles and Guidelines. It does not repeat the guidance in Part 1. Rather, it adds guidance and techniques to help authors make sure that readers or users of…

This document specifies the quality, safety requirements and test methods for Euodiae (Evodiae) fructus that is derived from the fruit of Euodia (Evodia) rutaecarpa (Juss.) Benth., Euodia (Evodia) rutaecarpa (Juss.) Benth. var. officinalis (Dode) Huang or Euodia (Evodia) rutaecarpa (Juss.) Benth. var. bodinieri (Dode) Huang (Tetradium ruticarpum (A. Juss.) T. G. Hartley). It is applicable to…

This proposal project specifies a method intended for determining the anti-contamination propensity of fabrics to particulate matter. This method is applicable to woven fabrics which may or may not have been given an anti-contamination to particulate matter finish. It is especially suitable for measuring apparel fabrics. It is not intended for use in fabrics that react to UV light or allow…

This document specifies methods for determining the amount of sulfur volatilized from vulcanized rubber under heating conditions using high performance liquid chromatograph (HPLC). The methods apply only to the sulfur which chemical formula is S8. The methods cannot be used above the thermal decomposition temperature of the rubber. Note 1 This methods determine the amount of sulfur that…

The standard ISO 16659-1 is the general part of a set of standards on the different in-situ test methods for iodine traps, describing common general provisions applicable to all methods. The current standard ISO 16659-2 presents the in-situ testing method for measuring the efficiency of iodine traps using a radioactive methyl iodine method (CH3I). This standard present the specific provisions…

This proposed standard is recommended a method for determining the performances and leak tightness of iodine adsorbers in nuclear air cleaning systems of personnel habitable spaces of nuclear facilities to solve the radiation safety and environmental safety problems of traditional test methods. The test flowchart and evaluation procedure of the cyclohexane method are given in the attachments of…
