The new European standard EN 14621 partially replaces the German standards DIN 53840 and DIN 53866, and contains crimp contraction- and shrinkage tests on multifilament yarns. Measurements according to the new standard can be automated by means of the automatic crimp- and shrinkage tester TEXTURMAT ME+.
New European Standard for Crimp- and Shrinkage Tests
The tester has already been in use for measurements according to the DIN standards as well as to ASTM D 4031 (crimp properties) and ASTM D 2259 (shrinkage). A special software for testing air-textured yarns enlarges the scope of application of this tester.
