Introduction
GB/T 5586-2016 Standard Core Interpretation
| Test Items | Measurement Principle | Instrument Requirements | Key Formulas |
|---|---|---|---|
| Density Measurement | Archimedes’ Principle, Calculate the Volume of an Object by the Buoyancy of a Liquid. | Precision Balance, Pycnometer, Thermometer, etc. | ρ = m₀ - (m₂ - m₃) × D₀ |
| Hardness Test | Brinell and Vickers Hardness, Calculate the Hardness of a Material by Indentation. | Brinell hardness tester, Vickers hardness tester and special indenter. | HBW = 0.102 × F / (π D (D - d²)) |
| Volume resistivity measurement | Double-arm bridge method, calculated by current-voltage relationship. | High-precision double-arm bridge, standard resistor, etc. | ρ = A × Rx / L |
