BS EN ISO 1856Flexible cellular polymeric materials. Determination of compression set
BS EN ISO 1856 is a test method that specifies three methods for determining the compression set of flexible cellular materials and applies only to latex and polyurethane foams of thickness greater than 2 mm.
This test standard is equivalent to ISO 1856.
Before conducting BS EN ISO 1856, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
