DESCRIPTION
BS 4029:1978
This standard BS 4029:1978 Method of test for the determination of tensile elastic recovery of single fibres and filaments (constant-rate-of-extension machines) is classified in these ICS categories:
- 59.060.01 Textile fibres in general
This British Standard specifies a method of test for the measurement of tensile elastic recovery of all types of single filaments or fibres when subjected to tensile strain applied by a constant-rate-of-extension machine. No special pre-treatments such as mechanical cycling or relaxation of internal stresses by immersion in boiling water are specified, although they may be required for some special purposes. This method does not determine the elastic recovery from a given stress.
Provides for mean values of immediate elastic recovery and for residual elongation after 1 minute.
