Card type: Test method

1. Method number / full name / English name / replacement relationship

• Method number: SH/T 0453-92
• Full name: Test method for water resistance and water-ethanol (1:1) solution) performance of lubricating grease
• English name: not provided in the available source
• Replacement relationship: replaces SY 4029-84
• Other: confirmed in 2004; identically adopts the United States Federal Test Method Standard FS 791 C (54150986) "Test method for water resistance and water-ethanol (1:1) solution) performance of lubricating grease"

2. Scope of application and non-applicability

• Scope of application: This standard is applicable to determining the performance of lubricating grease against the dissolving action of water and water-ethanol (1:1) solution).
• Not applicable: not provided in the available source

3. Method principle

Divide the sample into two portions, place one portion in distilled water and the other in water-ethanol solution, and after one week inspect the samples for disintegration.

4. Reagents and materials (purity / preparation)

• 95% Ethanol: chemically pure, conforming to GB/T 679
• Distilled water: specification not stated in the source text
• Water-ethanol solution: ethanol-distilled water volume ratio 1:1

5. Apparatus and equipment

• Glass container: 250 mL, stoppered, two

6. Recommended operating conditions

• Temperature: room temperature
• Standing time: one week
• Other: not provided in the available source

7. Sampling and sample preparation

• Sample about 4 g
• Small grease portions separated from the sample, each about 2 g

8. Analytical procedure

7.1 Pour 200 mL distilled water into one glass container, and pour 200 mL ethanol-distilled water (volume ratio 1:1) into another glass container. 7.2 Place the two sample portions (small grease portions separated from the sample, each about 2 g) respectively into the two containers, firmly stopper the containers, and let stand at room temperature for one week. 7.3 After one week, shake the containers once or twice, then visually inspect the degree of disintegration of the sample in each container.

9. Qualitative and quantitative determination and calculation formula

• Qualitative and quantitative method: visual inspection of the degree of disintegration of the sample in each container
• Calculation formula: not provided in the available source

10. Precision

not provided in the available source

11. Report

Report the degree of disintegration of the lubricating grease sample in each container.
