Introduction

GB/T 36412—2018 Inspection and calibration of force standard machines: professional interpretation

1. Background of standard formulation and analysis of technological evolution

As the core tool of measurement and calibration equipment, the accuracy and reliability of force standard machines are directly related to the quality of measurement results. GB/T 36412—2018 "Inspection and calibration of force standard machines" is based on the general technical requirements for testing machines (GB/T 2611) and the relevant specifications of the Machinery Industry Federation, combined with the development of advanced technologies at home and abroad, and comprehensively stipulates the technical requirements, inspection methods and calibration processes of force standard machines. This standard is applicable to deadweight, lever, hydraulic and superposition force standard machines to ensure their performance stability and measurement accuracy in different application scenarios.

2. Comparative analysis of standard frameworks

Types of force standard machines	Technical requirements dimensions	Main technical indicators	Applicable scenarios
Static gravity force standard machine	Accuracy level and error range	±0.01% (0.01 grade), ±0.03% (0.03 grade) Relative error of force value	High-precision calibration, static force measurement
Lever type force standard machine	Amplification ratio error and discrimination force threshold	±0.01% (0.03 grade), ±0.02% (maximum force) Discrimination threshold	Dynamic force testing, medium precision requirements
Hydraulic force standard machine	Working pressure and cylinder plug system performance	±0.03% (0.05 grade), ±0.1% (maximum force) Relative error	High dynamic range testing, large tonnage calibration
Superposition force standard machine	Modular combination and repeatability	±0.03% (0.1 grade), Force value fluctuation does not exceed 0.01%	Multi-purpose calibration, complex system integration

3. Standard implementation recommendations

3.1 Preparation before implementation

Ensure that the inspection and calibration environment meets the standard requirements (temperature, humidity, vibration control).
Equip with standard force measuring instruments and measuring tools that meet technical requirements.
Establish a complete inspection record and calibration archive system.

3.2 Control of key technical parameters

In actual applications, the key technical parameters of force standard machines include amplification ratio error, discrimination force threshold and relative force error. For example, in a lever-type force standard machine, the maximum allowable value of the amplification ratio error is ±0.01%, while the maximum allowable value of the amplification ratio error of a hydraulic force standard machine is ±0.03%. These parameters directly affect the accuracy and repeatability of the measurement results.

4. Conclusion

GB/T 36412—2018 "Inspection and Calibration of Force Standard Machines" provides comprehensive technical specifications and implementation guidelines for the design, manufacture and application of force standard machines. By strictly following this standard, the accuracy and reliability of the measurement system can be ensured and the quality of experimental data can be improved.

It is recommended that practitioners in related industries regularly participate in professional training, familiarize themselves with the content of the standard, and optimize the inspection and calibration process in combination with actual application scenarios.
