Abstract

Ïã¸ÛÁùºÏ²Ê¿ª½± 281:2007 introduced a life modification factor, aÏã¸ÛÁùºÏ²Ê¿ª½±, based on a systems approach to life calculation, in addition to the life modification factor, a1.These factors are applied in the modified rating life equation, Lnm = a1aÏã¸ÛÁùºÏ²Ê¿ª½±L10. The modification factor for reliability, a1, for a range of reliability values, is given in Ïã¸ÛÁùºÏ²Ê¿ª½± 281:2007 as well as the method for evaluating the modification factor for systems approach, aÏã¸ÛÁùºÏ²Ê¿ª½±. L10 is the basic rating life.

Ïã¸ÛÁùºÏ²Ê¿ª½±/TR 1281-2:2008 gives supplementary background information regarding the derivation of a1 and aÏã¸ÛÁùºÏ²Ê¿ª½±.
