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…
Photography — Room-light loading packages for electronic scanners and image-setting film and paper r...
This International Standard applies to room-light loading packages either containing photographic film or paper rolls
for electronic scanners or image-setting devices. It specifies the dimensions of the package and its contents, critical
equipment interfacing features, and package marking. The prime aim of this International Standard is to ensure
compatibility between room-light loading packages…
Optical fibres - Part 1-45: Measurement methods and test procedures - Mode field diameter
Establishes requirements for measuring the mode field diameter (MFD) of fibres. Four methods are described: (a) direct far-field scan: (b) variable aperture in the far field: (c) near-field scan: (d) bi-directional backscatter using an optical time domain reflectometer. All four methods apply to type B single-mode fibres, operating near 1310 nm or 1550 nm.
