<p>Specifies a method of determing the tear resistance of plastic film or sheet less than 1 mm thick, tested under defined conditions. A rectangular test specimen having a longitudinal slit extending over its half length is subjected to a tensile test on the "trouser legs" formed by the slit. The average force required to tear the specimen completely along its length is used to calculate the tear resistance in N/mm.</p>
