ISO 6914:2008 describes three methods for the measurement of the change of stress in a test piece at a given elongation for the purpose of determining the ageing characteristics of a rubber. Method A is intended for measurement under continuous strain conditions. Method B is the preferred method for measurement under intermittent strain conditions. In the case of both methods A and B, a stress…

ISO 21570:2005 provides the overall framework of quantitative methods for the detection of genetically modified organisms (GMO) in foodstuffs, using the polymerase chain reaction (PCR). It defines general requirements for the specific amplification of DNA target sequences in order to quantify the relative GMO-derived DNA content and to confirm the identity of the amplified DNA sequence.…

"This procedure defines the long-term thermal resistance (LTTR) of a foam product as the value measured after 5-year storage in a laboratory environment and provides means for its prediction based on an accelerated laboratory test. This procedure, based on ASTM standard test methods C 1303 and C 518, can be applied to a wide range of preformed as well as field manufactured insulating foams.…

ISO 28080:2011 specifies a generic test method to determine the abrasion wear characteristics of hardmetals. The procedure complements the ASTM G65 method for dry sand/rubber wheel abrasion, the ASTM B611 method for abrasive wear resistance of cemented carbides, and the ASTM G105 method for conducting wet sand/rubber wheel abrasion tests. The test is appropriate for use in situations where test…

ISO 17873:2004 specifies the applicable requirements concerning the design and use of ventilation systems in nuclear installations such as hot cells, nuclear fuel fabrication and examination laboratories, plutonium-handling facilities, reprocessing plants, enrichment facilities, nuclear-waste treatment stations, storage facilities, etc. The purpose of ventilation and containment systems is to…

This International Standard specifies two laboratory test methods, based on slicing and scaling techniques, to determine the long-term changes in the thermal resistance of closed-cell (normally 90 %) cellular plastic materials that contain gases which, through diffusion processes, affect the properties of a foam with time. Using standard methods for the measurement of thermal resistance, method A…

ISO 16701:2003 defines an accelerated corrosion test method to be used in assessing the corrosion resistance of metals in environments where there is a significant influence of chloride ions, mainly as sodium chloride from a marine source or road de-icing salt. ISO 16701:2003 specifies the test apparatus and test procedure to be used in conducting the accelerated corrosion test to simulate, in a…

1. SCOPE 1.1 This procedure defines the long-term thermal resistance (LTTR) of a foam product as the value measured after 5-year storage in a laboratory environment and provides means for its prediction based on an accelerated laboratory test. 1.2 This procedure, based on ASTM standard test methods C 1303 and C 518, can be applied to a wide range of preformed as well as field applied…

ISO 9917-2:2017 specifies requirements and test methods for water-based dental cements in which setting is achieved by a combination of an acid-base reaction and polymerization. The materials are intended for luting, base or lining, restoration and tooth core build up purposes. EXAMPLE Conventional glass polyalkenoate cements are normally formed by reacting an ion-leachable aluminosilicate glass…

ISO 17081:2014 specifies a laboratory method for the measurement of hydrogen permeation and for the determination of hydrogen atom uptake and transport in metals, using an electrochemical technique. The term "metal" as used in ISO 17081:2014 includes alloys. ISO 17081:2014 describes a method for evaluating hydrogen uptake in metals, based on measurement of steady-state hydrogen flux…
