Introduction
Core changes in the standard revision
| Technical dimension | Requirements of the 2017 version | Changes in the 2025 version | Technical impact |
|---|---|---|---|
| Definition of terms | 4 terms | Reduced to 3, with a new definition of Wear spot diameter (WSD) | Unified measurement indicator expression |
| System composition | Basic structure | Six new components such as vibration shaft and friction sensor | Measurement accuracy improved by 30% |
| Temperature control requirements | ±3℃ | Tightened to ±2℃ | Improved data repeatability |
Analysis of key technical requirements
4.1 Test machine system composition
The new standard clarifies that the high-frequency reciprocating test machine must include three major systems:
- Host system: vibration frequency 50Hz±1Hz, load 200g±1g
- Temperature and humidity control system: oil sample temperature 60±2℃, humidity control range see Figure 2
- Data measurement system: microscope resolution ≥2048×1536 pixels
Implementation and application suggestions
Key points for laboratory upgrade
- Existing equipment needs to add stroke displacement sensor (accuracy 0.02mm)
- The temperature control system should upgrade the PID algorithm to meet the ±2℃ requirement
- Wear spot measurement uses a digital microscope equipped with a standard ruler
Standard transition period operation
Before December 31, 2025, reports can be issued according to the 2017 version, but the note "based on the old version of the standard" is required. It is recommended to carry out the following in advance
- Equipment metrology calibration (focus on checking the load and temperature modules)
- Operator training (new terminology and judgment rules)
- Reference oil update (purchased according to clause 7.3)
