IEC 60512-16-21:2012 The object of this standard is to define a standard test method to assess the possibility of whisker growth by external mechanical stress on the tin and tin-alloy plated parts of a connector in its application (after wire termination, after soldering, after mounting, mated with counterpart). This standard does not cover internal stress type whisker. This part of IEC 60512,…

This International Standard specifies requirements and test methods for foam proportioning equipment of fixed foam extinguishing systems for indoor or outdoor use or both.

This International Standard specifies requirements and test methods for low expansion foam equipment of fixed-foam extinguishing systems for indoor or outdoor use or both. This International Standard is applicable to sprayers, branchpipes, monitors, low expansion foam generators, foam chambers, etc.

ISO 15174:2012 specifies a method for comparison of the total milk-clotting activity of a microbial coagulant sample with the milk-clotting activity of an international microbial coagulant reference standard on a standard milk substrate prepared with a calcium chloride solution of concentration 0,5 g/l (pH ~6,5).

1.1 Scope 1.1.1 This standard applies to: a. The mechanical and electrical features of newly manufactured systems that dispense compressed hydrogen gas for vehicles (HGV) where such systems are intended primarily to dispense the fuel directly into the fuel storage container of the vehicle. b. HGV dispensers that integrate in a single unit multiple dispensing functions (e.g., fuel metering…

1.1 Scope 1.1.1 This standard contains safety requirements for material, design, manufacture and testing of gaseous hydrogen hose and hose assemblies. This standard applies to newly manufactured hose and hose assemblies for: • connecting the dispenser to the fueling nozzle, high pressure (class A) • used as part of a vehicle on-board fuel storage system, high pressure (class B) • used as…

IEC 61000-4-4:2012 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61000-4-4:2012 relates to the immunity of electrical and electronic equipment to repetitive electrical fast…

ISO 13183:2012 specifies the architectural communications framework of intelligent transport systems (ITS) for the family of communications access for land mobiles (CALM) related International Standards. The architecture is described in an abstract way with several graphical views and examples. The graphical representations partly follow the ISO open systems interconnection (OSI) principles. In…

1 Scope This International Standard specifies specimen dimensions, testing equipment and the procedure for torsion testing of resistance spot welds with single sheet thicknesses ranging from 0,5 mm to 6,0 mm in steels. It can be used for non-ferrous materials in certain circumstances. The aim of this International Standard is to determine the weld diameter and the failure type of fractured…

This International Standard specifies the treatments for the measurement of the stability of soil aggregates. It can be applied to a wide range of materials originating mainly from the tilled horizons of cultivated soils. It can, however, also apply to any soil profile horizon, whether it is cultivated or not. Aggregates ranging from 3 mm to 5 mm are measured. However, the presence of gravel in…
