Introduction
GB/T28878.4-2016 Standard Overview
GB/T28878.4-2016 "Specifications for Rotating Components in Space Science Experiments Part 4: Acceptance of Lubricating Oils" is a Chinese national standard that mainly specifies the acceptance conditions, processes, requirements and inspection rules for lubricating oils used in rotating components of space science experimental devices. This standard is applicable to the quality acceptance of commonly used lubricating oils and greases such as chlorophenyl silicone oil and polyalphaolefin synthetic hydrocarbon oil.
Background of Standard Formulation and Technical Evolution
With the continuous development of space science experiments, the requirements for rotating components are becoming increasingly stringent, especially the performance requirements in extreme environments. GB/T28878.4-2016 was formulated based on previous technical research results and practical experience, aiming to ensure the reliability, durability and safety of lubricating oils in space environments. The evolution of the standard reflects the gradual deepening from basic research to practical application.
Lubricating oil acceptance conditions and process
| Acceptance stage | Key requirements | Test method |
|---|---|---|
| Appearance inspection | Transparent and uniform | GB/T6540 |
| Density detection | Range control | GB/T2013 |
| Kinematic viscosity | Indicators at specific temperature | GB/T265 |
Implementation suggestions and actual cases
Implementation suggestions:
- Establish a complete lubricant acceptance system to ensure compliance with GB/T28878.4-2016 requirements.
- Strengthen the calibration and maintenance of testing equipment to ensure data accuracy.
- Train professionals to improve standard implementation capabilities.
