Two procedures are described that permit the measurement of shrink forces at predetermined temperatures. They are as follows:<\/p>\n<p id=\"s00003\">1.1.1 <span class=\"italic\"><span class=\"italic\">Procedure A<\/span><\/span> is designed to measure the maximum force exerted by a specimen that is totally restrained from shrinking as it is heated rapidly to a specific temperature.<\/p>\n<p id=\"s00004\">1.1.2 <span class=\"italic\"><span class=\"italic\">Procedure B<\/span><\/span> is designed to measure the maximum force exerted by a specimen that is permitted to shrink a predetermined amount prior to restraint while being heated rapidly to a specific temperature.<\/p>\n<p id=\"s00005\">1.2 Orientation release stress can be determined from the data obtained using Procedure A.<\/p>\n<p id=\"s00006\">1.3 The values stated in SI units are to be regarded as the standard.
