DESCRIPTION

BS ISO 15373:2001


This standard BS ISO 15373:2001 Plastics. Polymer dispersions. Determination of free formaldehyde is classified in these ICS categories:
  • 83.080.20 Thermoplastic materials

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 dispersions with a free-formaldehyde content higher than 10 mg/kg. Method B is recommended if lower formaldehyde contents have to be determined or arbitration analyses have to be carried out.

Both methods minimize changes in free-formaldehyde concentration that can result from changes in the physical or chemical properties of polymer dispersions.

There are no known limitations to these methods when used in the manner described.
