Composite string insulator units for overhead lines with a nominal voltage greater than 1000 V - Par...
Prescribes specified values for the mechanical characteristics of
the composite string insulator units. Defines the main dimensions
of the couplings to be used on the composite string insulator units
in order to permit the assembly of insulators of fittings supplied
by different manufacturers and to allow, whenever practical,
interchangeability with existing installations.
It also defines a…
Natural gas — Determination of water content at high pressure
Describes a method of determining the water content of natural gas under pressure of more than 1 MPa. Also applicable to natural gas, containing hydrogen sulfide with a water concentration of 10 mg/m^3 or more.
Transmission of audio and/or video and related signals using infra-red radiation - Part 1: General
Gives methods of measuring and specifiying the common technical features of systems using diffusely radiated or wide beams of infra-red radiation as carriers of information, mainly representing audio and/or video, but also control data related to audio and video apparatus. The contents of the corrigendum of May 1997 have been included in this copy.
1 Purpose
The purpose of this standard is to specify the physical, chemical and
biological characteristics of compost as well as the sampling methodology and
the methods of analysis that shall be used to verify these characteristics.
2 Scope
This standard applies to compost from different sources used as organic soil
conditioners, sold or distributed in bag or in bulk.
Processed cheese and processed cheese products — Calculation of the content of added citrate emulsif...
Gives a method for the calculation of the approximate content of added citrate emulsifying agents and acidifiers/pH-controlling agents, expressed as citric acid, in processed cheese and processed cheese products. Does apply to cheeses and cheese products which contain no major ingredients with an appreciable content of citric acid.
Abrasive grains and crude — Chemical analysis of silicon carbide
Relates to the chemical analysis of silicon carbide. Applicable for the determination of the surface impurities of abrasive grains and determining the SiC content of crushed crude when the silicon carbide content is greater than 95 %.
Plastics piping systems — Glass-reinforced plastics (GRP) components — Determination of the amounts ...
Method for the determination of constituents of a test sample cut from glass-reinforced plastics. It includes the determination of resin, glass, aggregate and filler contents. Technically identical to EN 637:1994.
Abrasive grains and crude — Chemical analysis of fused aluminium oxide
Deals with the chemical analysis of abrasive grains based on fused aluminium oxide. Describes the gravimetric, colorimetric and the atomic absorption spectrometric determination of the silicon dioxid, iron oxide, titanium oxide, calcium oxide, magnesium oxide, zirconium oxide and aluminium oxide content and the loss on ignition.
