: The standard includes tests for determining residual extension (how much a fabric stays stretched after tension is released) and tension decay .
: It outlines methods to determine the stretchability (extension) of a fabric at a specified force and its modulus—the tensile force required to produce a specific elongation. bs 4952 pdf
Some national libraries (British Library, National Library of Scotland) allow on-premises access to BSI standards. If you are a student or researcher, check your university library’s e-resources—many have a “BSI Online” subscription. : The standard includes tests for determining residual
