Explosive atmospheres - Part 39: Intrinsically safe systems with electronically controlled spark dur...
IEC TS 60079-39:2015(E) specifies the construction, testing, installation and maintenance of Power-i apparatus and systems which utilise electronically controlled spark duration limitation to maintain an adequate level of intrinsic safety. This Technical Specification contains requirements for intrinsically safe apparatus and wiring intended for use in explosive atmospheres and for associated…
Information technology - UPnP Device Architecture - Part 3-10: Audio Video Device Control Protocol -...
This service definition is compliant with the UPnP Device Architecture version 1.0.
This service type enables control over the transport of audio and video streams. The service type defines a ?common' model for A/V transport control suitable for a generic user interface. It can be used to control a wide variety of disc, tape and solid-state based media devices such as CD players, VCRs and…

Leather — Determination of ethoxylated alkylphenols — Part 1: Direct method
ISO 18218-1:2015 is a method for determining ethoxylated alkylphenols (nonyphenol ethoxylate [NPEOn with 1 ≤ n ≤ 16] and octylphenol ethoxylate [OPEOn with 1 ≤ n ≤ 16]) in leather. This direct method is especially suitable where a larger number of leather samples are to be checked for the presence of ethoxylated alkylphenols.
This method requires the use of high-performance liquid chromatography…
Leather — Determination of ethoxylated alkylphenols — Part 2: Indirect method
ISO 18218-2:2015 is a method for determining alkylphenols (nonylphenol and octylphenol) and alkylphenol ethoxylates (nonylphenol ethoxylate and octylphenol ethoxylate) in leather and process auxiliaries. The analysis is based on high-performance liquid chromatography (HPLC) or gas chromatography-mass spectrometry (GC-MS).
The analysis of the alkylphenol ethoxylate is made by cleaving the…
Synthetic rubber latex — Preparation of dry polymer
ISO 2028:2015 specifies four methods for the isolation of dry polymer from synthetic polymer latices containing anionic surfactants, for the purpose of subsequent testing. Tests to be performed include the determination of the Mooney viscosity, the bound-styrene or acrylonitrile content in the polymer chain or the mill shrinkage.
Rubber — Determination of total sulfur content by ion chromatography
ISO 19242:2015 specifies a method for the determination of the total sulfur content of raw rubber and unvulcanized or vulcanized rubber compounds by ion chromatography following the preparation of a sample solution using either a tubular furnace combustion or an oxygen combustion flask method.
The tubular furnace combustion method is applicable for rubbers with sulfur content less than 0,1 % as…
