2012 NIST Handbook 156 Program Handbook for Engine Fuels, Petroleum and Lubricant Laboratories

This handbook provides guidance on how to establish a management system for Fuel Quality Laboratories (FQL) using the International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) ISO/IEC 17025:2005, "General Requirements for the Competence of Testing and Calibration Laboratories (17025)." This handbook includes standards similar to those in 17025 and NIST Handbook 143 "State Weights and Measures Metrology Laboratories - Program Handbook" except that 17025 and Handbook 143 impose mandatory requirements. This handbook is intended as guidance, so the "shalls" in the handbooks on which it is based have been replaced with "shoulds" to make it clear that the text is only recommended.
