BS 7918-1:1999

This standard BS 7918-1:1999 Visual imperfections in rubber products is classified in these ICS categories:

• 01.040.83 Rubber and plastics industries (Vocabularies)
• 83.060 Rubber

This British Standard defines terms used to describe the visual imperfections sometimes found in rubber products. The vocabulary is supplemented by schematic drawings which illustrate the terms.

Imperfections in cellular products, for example gloss and colour imperfections, and instrumental methods of measurement are outside the scope of this standard, as are toroidal sealing rings (O-rings), for which reference should be made to BS 6442.
