Industry Standard Specification for Universal Components (2)
1. Firmness and Durability
Universal components shall possess a firmness, durability and toughness comparable with that of the original material. It shall withstand vibrations, corrosion and wear off, and maintain its integrity during use under regular conditions.
2. Quality Grade
Universal components shall conform to the quality grade A, B and C as specified in the relevant standards.
3. Finish
Universal component shall remain in a consistent high level finish throughout. The finish shall match the following requirements:
• Surface finish: smooth and polished to a gleaming finish with no visible cracks, burrs or rough edges.
• Markings: Clear and legible.
4. Electroplating
Universal component shall be electroplated to a consistent and standard finish. The electroplating shall meet the following requirements:
• Electroplating density: 15-33 microinches.
• Electroplating thickness: 0.5-5.5 mils.
• Hardness: 60-63 HV.
5. Heat Treatment
Universal component shall be able to withstand thermal shock and hostile environments. Heat treatment shall meet the following requirements:
• Quenching temperature: 450-850℃ (840-1560℉).
• Tempering temperature: 300 - 450℃ (570-840℉).
• Hardness: 45-50 HRC.
• Tensile strength: 400 – 900 N/mm2 (58-130 ksi).
6. Comparative Analysis
Universal component manufacturers shall conduct a comparative analysis of the component design and performance with the specific material or product being replaced or improved, and report the results in the form of a report.
7. Corrosion Resistance
Universal component shall be able to withstand extreme wear, corrosion and prolonged exposure to hostile environments and corrosive agents. The component shall meet the following requirements:
• Surface preparation: Component shall be prepared to withstand various corrosive elements and conditions.
• Corrosion resistance: Component must not corrode more than 60 milligrams per square meter (msm) of surface area per day in any environment.
8. Lubrication
Universal component should be able to survive in a wide range of temperatures and pressure conditions with minimal lubrication. Lubrication shall meet the following requirements:
• Compatibility: Lubrication shall be compatible with the component and the environment in which it is to be used.
• Performance: Lubrication shall be able to effectively reduce friction, wear and tear, and extend component life.
• Oil content: Lubrication shall not exceed the maximum oil content specified in relevant standards.
9. Durability and dimensional accuracy
Universal component must retain its strength and durability, and maintain dimensional accuracy even when subjected to wear and tear, temperature variation, external forces and stress.
10. Affordability
Universal component should offer good value for money. The cost of the component should be fair and reasonable in comparison to similar products and manufactured components available in the market.
