ISO 3750:2006 specifies a flame atomic absorption spectrometric method for the determination of magnesium in zinc alloys. It is applicable to the products specified in ISO 301 and ISO 752.
It is suitable for the determination of magnesium contents (mass fractions) between 0,002 % and 0,08 %.
Animal feeding stuffs — Determination of aflatoxin B1
ISO 17375:2006 specifies a method for the determination of aflatoxin B1 in animal feeding stuffs using high-performance liquid chromatography with post-column derivatization.
It is applicable to animal feeding stuffs with a fat content of up to 50 %.
The limit of quantification of this method has been demonstrated to be better than 0,5 g/kg for aflatoxin B1 for a signal-to-noise ratio of 6.
Stationary source emissions — Sampling and determination of gaseous fluoride content
ISO 15713:2006 is applicable to the measurement of the gaseous fluorides that are entrained in gases carried in stacks or ducts. The gaseous fluoride content is expressed as a mass of hydrogen fluoride in the stack gas.
ISO 15713:2006 is applicable to all stacks emitting gases with fluoride concentrations of below 200 mg/m3. It can be used for higher concentrations, but then the absorption…

ISO 1833-13:2006 specifies a method, using carbon disulfide/acetone, to determine the percentage of chlorofibre, after removal of non-fibrous matter, in textiles made of mixtures of certain chlorofibres, whether after-chlorinated or not, and wool, animal hair, silk, cotton, viscose, cupro, modal, polyamide, polyester, acrylic and glass fibres.
When the wool or silk content of a mixture exceeds 25…
Textiles — Quantitative chemical analysis — Part 15: Mixtures of jute and certain animal fibres (met...
ISO 1833-15:2006 specifies a method, by determining the nitrogen content, to calculate the proportion of each component, after the removal of non-fibrous matter, in textiles made of binary mixtures of jute and animal fibres.
The animal-fibre component may consist solely of hair or wool, or of any mixtures of the two.
ISO 1833-15:2006 is not applicable to products in which dyestuffs or finishes…
Textiles — Quantitative chemical analysis — Part 7: Mixtures of polyamide and certain other fibres (...
ISO 1833-7:2006 specifies a method, using formic acid, to determine the percentage of polyamide fibre, after removal of non-fibrous matter, in textiles made of binary mixtures of polyamide and cotton, viscose, cupro, modal, polyester, polypropylene, chlorofibre, acrylic or glass fibre.
It is also applicable to mixtures with wool and animal hair, but when the wool content exceeds 25 %, the method…
