Rubber — Nitrile latex — Determination of bound acrylonitrile content
Specifies a method for the determination of the bound acrylonitrile content of emulsion-polymerized NBR latices. Does also apply to carboxylic-nitrile-butadiene (XNBR) latices and nitrile-isoprene (NIR) latices. Replaces the first edition.
Soil quality — Determination of water content in the unsaturated zone — Neutron depth probe method
Specifies a non-destructive method for the determination of water content in the unsaturated zone of soils using a neutron depth probe. Water content profiles can be obtained by measuring at a series of depths of soil.
Low-voltage switchgear and controlgear - Part 2: Circuit-breakers
States the characteristics of circuit breakers, the conditions with which they shall comply: (operation and behaviour in normal service, operation and behaviour in case of overload and operation and behaviour in case of short-circuit, dielectic properties), tests intended for confirming that these conditions have been met and the methods to be adopted for these tests, and information to be marked…
Electrical apparatus for explosive gas atmospheres - Part 10: Classification of hazardous areas
Is concerned with the classification of hazardous areas where flammable gas or vapour risks may arise, in order to permit the proper selection and installation of apparatus for use in such hazardous areas. The contents of the corrigendum of May 1996 have been included in this copy.
Rubber, raw natural — Determination of dirt content
Specifies a method for the determination of the dirt content of raw natural rubber. Not applicable to dirt present as surface contamination. Replaces the second edition which has been technically revised.
Rubber compounding ingredients — Carbon black (pelletized) — Determination of dust content
Specifies a method for the determination of the dust content of pelletized carbon blacks. Permits a differentiation to be made between micro-pellets and dust and is applicable to all pelletized carbon blacks for the rubber industry.

Gives requirements for blast-cleaning abrasives from fused aluminium oxide (corundum). Specifies ranges of particle sizes and values for apparent density, bulk density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides.
Insulating bushings for alternating voltages above 1000 V
Specifies the characteristics and tests for insulated bushings. Is applicable to bushings, as defined in clause 2, intended for use in electrical apparatus, machinery, transformers, switchgear and installations for three-phase alternating current systems, having rated voltages above 100 V and power-frequencies of 15 Hz up to and including 60 Hz. Special requirements and tests for transformer…
Latex, rubber, natural concentrate — Determination of dry rubber content
Gives a method for the determination of the dry rubber content of natural rubber latex concentrate. Replaces the third edition which has been insignificantly revised.
