Petroleum products — Determination of the filterability of lubricating oils — Part 1: Procedure for ...
ISO 13357-1:2017 specifies a procedure for the evaluation of the filterability of lubricating oils, particularly those designed for hydraulic applications, in the presence of water. The procedure only applies to mineral-based oils, since fluids manufactured from other materials (e.g. fire-resistant fluids) may not be compatible with the specified test membranes. The range of application has been…

Information technology — General-Purpose Datatypes (GPD)
ISO/IEC 11404:2007 specifies the nomenclature and shared semantics for a collection of datatypes commonly occurring in programming languages and software interfaces, referred to as the General-Purpose Datatypes (GPD). It specifies both primitive datatypes, in the sense of being defined ab initio without reference to other datatypes, and non-primitive datatypes, in the sense of being wholly or…
Coffee and coffee products — Determination of acrylamide — Methods using HPLC-MS/MS and GC-MS after ...
ISO 18862:2016 specifies methods for the determination of acrylamide in coffee and coffee products by extraction with water, clean-up by solid-phase extraction and determination by HPLC-MS/MS and GC-MS. It was validated in a method validation study on roasted coffee, soluble coffee, coffee substitutes and coffee products with ranges from 53 μg/kg to 612,1 μg/kg.
Information technology for learning, education and training — Language accessibility and human inter...
ISO/IEC 20016-1:2014 states the principles, rules and metadata elements for specifying language accessibility and Human Interface Equivalents (HIEs) in e-learning environments. It is structured to be able to support the requirements of applicable jurisdictional domains and in particular that of the UN Convention on the Rights of Persons with Disabilities.
Plain bearings — Testing of the tribological behaviour of bearing materials — Part 1: Testing of bea...
1 Scope
This part of ISO 7148 specifies tribological tests of metallic bearing materials for plain bearings under conditions of boundary lubrication.
The test procedures described in this part of ISO 7148 enable the friction and wear behaviour of bearing material/mating/lubricant combinations to be compared with that of other combinations, thus facilitating the selection of a bearing material for…
