NIST – HANDBOOK 44 – 2012 Edition
- The purpose of Handbook 44 is to prevent the use of weights and measures and weighing and measuring devices that give readings that are false, faulty (that is, that are not reasonably permanent in their adjustment or will not repeat their indications correctly), or that facilitate the perpetration of fraud. It has been designed to be a working tool for federal, state, and local weights and measures officials, the equipment manufacturers, installers, and service agencies/agents. Many organizations cite the Handbook in calibration or quality documentation.
- NTEP certification is issued by NCWM upon successful completion of the evaluation process. This Certificate indicates that the device manufacturer has demonstrated the ability to meet applicable requirements for commercial weighing and measuring equipment in the U.S as specified in NIST Handbook 44. NTEP certification is required in most states in the United States and is a symbol of assurance for all.
