标准范围

规定了在标准试验条件下，通过煮沸正庚烷，测定可从结晶丙烯塑料中提取的物质百分比的方法。在24小时内，将粉末状试样小心干燥、称重，并在索氏仪器中用正庚烷萃取。测定试样残留物的质量，并根据ISO 1873-1报告为等规。

Specifies a method for determining the percentage of matter which can be extracted from crystalline propylene plastics by boiling n-heptane under standard conditions of testing. A powdered test portion is carefully dried, weighed and extracted in as Soxhlet-apparatus with n-heptane during 24 h. The mass of residue of the test portion is determined and according to ISO 1873-1 reported as isotactic.
