BS 4524:1983

This standard BS 4524:1983 Method for determination of residue on evaporation on a water bath is classified in these ICS categories:

• 71.080.01 Organic chemicals in general

This International Standard specifies a general method for the determination of the dry residue, after evaporation on a water bath, of volatile organic liquids for industrial use.

The method is applicable to products having dry residues after evaporation greater than or equal to 10 mg/kg [0,001 % (m/m)].

NOTES

1 For the determination of the non-volatile residue of fluorinated hydrocarbons for industrial use, see ISO 5789.

2 For the determination of the residue on evaporation of aromatic hydrocarbons, or other toxic volatile materials, having residues on evaporation of not less than 1 mg/100 ml, see ISO 5277.

Determination of mass of residue, if any, after evaporation of a test portion on a hot water bath and drying to constant mass at 110°C. Applicable to organic liquids which can be volatized on a hot water bath.
