Verification procedures for non-self-propelled indicating scales
This standard is applicable to the initial verification and subsequent verification of non-self-propelled indicating scales (hereinafter referred to as "group") with medium accuracy and ordinary accuracy of the standard 1955-1997 standard.
Non-self-propelled indicating scales are scales that are completely operated by personnel, mainly including various mechanical lever scales such as mobile Case science, platform scales; fixed floor scales, mechanical hanging scales, etc., 2 Terminology
J[G555.1996 Some terms of general control procedures for non-mobile equipment are applicable to this regulation. To facilitate the counting and calibration, special attention is paid to some technical explanations in its metrological management. 2.1 Scale chain
All the work performed to verify the metrological performance of the scale and determine whether it meets the statutory requirements. 2.2 Inspection
The inspections that have never been calibrated and the inspections performed are Note: Diagnosis and calibration include: initial and new installation inspections: 2.3 Subsequent inspection
Calibration after the first calibration.
: Given:
b After repair:
The instrument is put into use with a certificate of replacement: <The calibration period is valid for the previous calibration, which is not related to the unit or the user. 2.4 In-use inspection
Inspect whether the scale in use meets the requirements of the measurement process: whether it is in good working condition; whether it is used correctly and reliably. In-use inspection is a kind of quality inspection: 3 Metrology and technical requirements
