BS 7959-1:2004

This standard BS 7959-1:2004 Materials used for the control of liquid spillages is classified in these ICS categories:

• 13.020.40 Pollution, pollution control and conservation
• 71.100.99 Other products of the chemical industry
• 75.180.99 Other equipment for petroleum and natural gas industries

This part of BS 7959 describes methods of sampling and determining the sorbency of materials used for the control of liquid spillages.

A variety of materials of different composition and format are used in this application and, for the purposes of this standard, the following categories are used.

• Type I web type sheet, pad or roll.
• Type II: loose material discrete particles of variable size.
• Type III: filled products socks, booms, pillows, cushions.
• Type IV: agglomerates masses of strands for pick-up of viscous liquids.
• The methods are applicable to sorbent materials of any type.

The standard also includes a test (swell ratio test, Clause 10) that will distinguish between absorbents and adsorbents.
