Test Method: SATRA TM129
Determination of the cold crack temperature of leather
September 1997
SCOPE
The method is intended to determine the cold crack temperature of a leather, the temperature at which the finish will crack when the leather is quickly folded once grain outwards. The method is mainly applicable to finished footwear upper leathers but can be used with any type of thin leather with a surface finish.
PRINCIPLE
A strip of leather is held between two pieces of wood forming a hinged apparatus. The leather is cooled and then creased grain outwards without touching it directly by hand, by closing the apparatus. The procedure is repeated at successively lower temperatures until cracking occurs.
