Specifies the content, format and recording method of the data blocks containing video, audio, and associated data that form the helical records on 12,65 mm tape in cassettes. Also specifies the content, format and recording method of the longitudinal record containing tracking information for the rotating head associated with the helical records, and also cue audio, and control tracks.
Aromatic extracts, flavouring and perfuming compounds — Determination of ethanol content — Gas chrom...
flavouring and perfuming compounds by gas chromatography, either on a packed column or a capillary column.
The method is applicable to those products having presumed ethanol contents over 0,5 %.
This International Standard specifies a method for the determination of the ash content of petroleum products, such
as distillate and residual fuel oils, crude petroleum, lubricating oils, waxes and other petroleum products, in which
any ash-forming constituents present are normally considered to be undesirable impurities or contaminants. Ash
can result from oil-soluble or water-soluble metallic…

Animal feeding stuffs — Determination of carbadox content — Method using high-performance liquid chr...
This International Standard specifies a high-performance liquid chromatographic (HPLC) method for the
determination of the carbadox content in premixtures and animal feeding stuffs.
The method is applicable to animal feeding stuffs with a mass fraction of carbadox of 0,5 mg/kg (limit of
quantification) to 100 mg/kg, and to premixtures with a mass fraction of carbadox up to 10 %.
The lower limit…
Plastics — Polymer dispersions — Determination of free formaldehyde
This International Standard describes two methods for the determination of free formaldehyde (HCHO) in polymer
dispersions. The procedure has been evaluated using acrylic, acrylonitrile butadiene, carboxylated styrenebutadiene
and vinyl acetate polymer dispersions. Both test methods may also be applicable to polymer dispersions
of other compositions.
Method A is the preferred method for polymer…
Electrical installations of buildings - Part 4-43: Protection for safety - Protection against overcu...
Describes how live conductors are protected by one or more devices for automatic interruption of the supply in the event of overload (see clause 433) and short-circuits (see clause 434) except in cases where the overcurrent is limited in accordance with clause 436 or by the conditions described in 433.4, 443.5 or 443.3 are met. Further, protection against overload and against short-circuits shall…
