ISO Standards

ISO 17608:2015 specifies a method to determine the resistance of bare elastane yarns to chlorinated aqueous environments, such as swimming pools, through testing of the breaking force retention. Different alternative test conditions are specified. Three different concentrations and two different exposure hours are considered. This International Standard is applicable to bare elastane yarns only. Result […]

ISO 17315:2014 specifies a test method for the determination of total acidity of ethanol by potentiometric titration. The total acidity is reported as acetic acid mass, in milligrams, per ethanol volume, in litres, or as mass percent of acetic acid (% m/m), if the density of ethanol is known. NOTE 1 For the purposes of

ISO 17278:2013 specifies a method for the determination of gel content for technically specified rubbers (TSR). WARNING — Persons using this International Standard should be familiar with normal laboratory practice. This International Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the

ISO 17223:2014 specifies an instrumental method for determining the yellowness index and change in yellowness index on clear, translucent, or opaque plastics. NOTE 1 Specimen shapes can include moulded plaques or discs, films, sheets, powders, and pellets. Plaque, disc,film, and sheet specimens can have smooth, matt, or patterned surfaces. Fluorescent plastics are not permitted. NOTE

ISO 17180:2013 specifies a method for the quantitative determination of free (non-protein-bound) lysine, methionine, and threonine in commercial products and premixtures containing more than about 10 % mass fraction of the respective amino acid. It does not distinguish between d- and l-forms. NOTE For the purposes of this International Standard, the term “amino acids” used

ISO 17088:2012 specifes procedures and requirements for the identifcation and labelling of plastics, and products made from plastics, that are suitable for recovery through aerobic composting. The four following aspects are addressed: a) biodegradation; b) disintegration during composting; c) negative effects on the composting process and facility; d) negative effects on the quality of the

ISO 17043:2010 specifies general requirements for the competence of providers of proficiency testing schemes and for the development and operation of proficiency testing schemes. These requirements are intended to be general for all types of proficiency testing schemes, and they can be used as a basis for specific technical requirements for particular fields of application.

ISO 16925:2014 specifies a test method for the assessment of the resistance of coatings to pressure water-jetting. The test method simulates the effects pressure water-jetting has on a coating.
