BS 7431:1991

This standard BS 7431:1991 Method for assessing solar water heaters. Elastomeric materials for absorbers, connecting pipes and fittings is classified in these ICS categories:

• 83.140.30 Plastics pipes and fittings for non fluid use
• 97.100.99 Heaters using other sources of energy
• 27.160 Solar energy engineering

This International Standard specifies a means of assessing elastomeric materials for use in the manufacture of absorbers, connecting piping and fittings for use in solar water heaters.
