Measuring instruments testing cycle to determine the principles and methods

Introduction

This Code refers to the International Organization of Standards and Metrology International Publication OIMLD10. 1984 "Testing Laboratory Using the measuring equipment calibration interval calibration guidelines "and the United States national standard laboratory assembly organized by NCSL RP-1..1996 "Confirmation and Adjustment of Calibration Intervals" was formulated in order to scientifically and reasonably determine that the meter with the test cycle, to ensure that the measuring instruments in the specified test cycle accurate and reliable.

1 Scope

This standard specifies the basic principles and methods for the determination of test cycles of measuring instruments.

This standard applies to the development or revision of measurement verification procedures for the determination of the measurement cycle of the applicable measuring instruments, at the same time it also serves as a reference for the adjustment of the calibration interval with the measuring instruments and the confirmation of the calibration interval with the measuring instruments.
