This International Standard specifies two test methods, designated method A and method B, for checking the leaktightness of glass-reinforced thermosetting plastics (GRP) pipes and fittings under short-term internal pressure. Method A is a hydraulic test applicable to a pipe under uniaxial stress. Method B is a pneumatic test applicable to fittings. NOTE Test methods for the leaktightness of…

This International Standard specifies a method, by analysis of inorganic carbon, for the evaluation in an aqueous medium of the ultimate aerobic biodegradability of organic substances at a given concentration of microorganisms. This International Standard is applicable to organic compounds which are: a) water-soluble under the test conditions; b) poorly water-soluble under the test conditions,…

This International Standard specifies a high-performance liquid chromatographic (HPLC) method for the determination of the furazolidone content of premixtures and animal feeding stuffs. The method is applicable to animal feeding stuffs with a furazolidone content of 25 mg/kg to 5 000 mg/kg and to premixtures with a mass fraction of furazolidone of up to 20 % [formerly written as 20 % (m/m)]. NOTE…

This Recommendation | International Standard is intended to provide the ODP Reference Model (see ITU-T Rec. X.902 | ISO/IEC 10746-2 and ITU-T Rec. X.903 | ISO/IEC 10746-3) with a language and environment neutral notation to describe computational operation interface signatures. Use of this notation does not imply use of specific supporting mechanisms and protocols.

The M Windowing API (MWAPI) extends the M programming technology with the addition of capabilities for developing and operating graphical user interface (GUI) applications. For the purposes of this International Standard, an application is defined as a collection of one or more M routines using MWAPI capabilities and a user is a person utilizing such an application.

This International Standard specifies requirements, test methods, and marking, labelling and packaging, as appropriate,of both permanent and temporary single-point anchor devices exclusively for the attachment of personalprotective equipment (PPE) for protection against falls from a height for fall arrest, work positioning and travelrestriction (work restraint).It is applicable only to anchor…

This International Standard specifies two procedures for the preparation of laboratory sheets prior to measuring thediffuse blue reflectance factor (ISO brightness). One is the traditional procedure based on preparation of sheets in aBüchner funnel using a filter paper or a wire screen. ln the other procedure, the sheets are prepared in a standardsheet former (conventional or Rapid Köthen).…

This International Standard gives guidance for the determination of total carbon (TC), total inorganic carbon (TIC) and total organic carbon (TOC) in drinking water, ground water, surface water, sea water and waste water. It also defines terms and specifies interferences, reagents, and sample pretreatment for water samples. The method described in this International Standard applies to water…
