PAR â Project Authorization Request An approved PAR is needed before official work is begun on a standard project. It serves as the work authorization by the IEEE-SA Standards Board. NesCom examines PARs and makes recommendations to the IEEE-SA Standards Board regarding their approval. An approved PAR is valid for 4 years. The PAR is referred to when the standard is submitted to RevCom for approval.
Par value. Par value is the face value, or named value, of a stock or bond. With stocks, the par value, which is frequently set at $1, is used as an accounting device but has no relationship to the actual market value of the stock. But with bonds, par value, usually $1,000, is the amount you pay to purchase at issue and the amount you receive when the bond is redeemed at maturity.
