Abstract
According to Method of Accelerated Determination for Shelf-life of Rubber Static Sealing Parts(HG/T 3087-2001)and Determination of the Life for Static Sealing Rubber Products(GB/T 27800-2021),the service life of rubber materials is calculated to be 14.37 and 15.21 a at room temperature of 298.15 K and elongation at break of 0.8,respectively.The service life of rubber materials calculated by the two methods is similar,because the regression model used by the two standards is the same,and the quadratic re-gression is carried out.The service life of rubber mate-rials calculated by the two methods is consistent with the engineering experience,so the service life of rubber materials can be predicted according to HG/T 3087-2001 and GB/T 27800-2021 in engineering practice.关键词
