This International Standard specifies a spectrometric method for the determination of the phosphorus content of
animal feeding stuffs.
The method is applicable to animal feeding stuffs with a phosphorus content less than 50 g/kg. It is particularly
appropriate for the analysis of products with low phosphorus content. For products with higher phosphorus content,
application of a gravimetric method…

This National Standard of Canada is equivalent to International Standard ISO
105-E03:1994.
1 Scope
This part of ISO 105 specifies a method for determining the resistance of the
colour of textiles of all kinds and in all forms to the action of active
chlorine in concentrations such as are used to disinfect swimming-pool water
(break-point chlorination).
Three alternative test conditions are…
Oilseeds — Simultaneous determination of oil and water contents — Method using pulsed nuclear magnet...
This International Standard specifies a rapid method for the determination of the oil and water contents of commercial oilseeds using pulsed nuclear magnetic resonance (NMR). It is applicable to rapeseeds, soya beans, linseeds and sunflower seeds with a water content less than 10 %. For seeds with higher water contents, drying is necessary before the oil content can be determined by pulsed NMR.…
