ISO 13347-2:2004 gives a detailed description of reverberant room methods for the determination of fan sound power levels. It is for use under standardized laboratory conditions and recognises that tests in situ are subject to increased uncertainty. These test procedures are not necessarily appropriate to site test conditions. Acoustic system effects are presently the subject of considerable…

This document specifies the principles, reagents and materials, test apparatus, test methods, evaluation of results and requirements for test reports using pilot tests for industrial cooling water systems. This document specifies a method to evaluate the performance of treatment programmes for open recirculating cooling water systems. It is based primarily on laboratory testing, but the heat…

The objective of this document is to assist conceptors, engineering offices, water companies or project owners in the design, installation and operation of the ductile iron pipeline systems for water supply: —     introduce practices for design, installation and operation of new ductile iron pipe water supply systems, rehabilitation or renovation; —     refers to existing standards that specify…

This document specifies the measurement method and requirements for combustion air inlet noise of air cleaners which are installed on reciprocating internal combustion engines, including laboratory measurement (engineering method and survey method) and site measurement (survey method). This document applies to all air cleaners installed on reciprocating internal combustion engines (reciprocating…

This document specifies quality requirements for manufacturers of thermal sprayed coatings to ensure quality assurance for activities in the field of production. NOTE      It is independent of the availability of a quality management system, e.g. ISO 9001, ISO 14001 and ISO 45001, which concern the concept and organization of the quality management. This document defines the quality requirements…

This document specifies a general outline of the ISO 3834 series and criteria to be taken into account for the selection of the appropriate level of quality requirements for fusion welding of metallic materials, among the three levels specified in ISO 3834-2, ISO 3834-3 and ISO 3834-4. It is applicable to manufacturing, both in workshops and at field installation sites. This document does not…

This document specifies a bioassay for the determination of the presence of unknown toxic contaminants in test seawater (see Figure A.1). It is based on the inhibition of photosynthetic activity of the marine cyanobacterium Cyanobium sp. (NIES-981) by such toxic contaminants. The inhibition is determined based on delayed fluorescence (DF) intensity. The method is rapid and requires less…
