2. Scope of application and non-applicability

• This standard specifies a test method for the stability performance of rust-preventive oils and greases under alternating hot and cold conditions.
• This standard applies to solvent-diluted rust-preventive oil, human sweat displacement rust-preventive oil, and rust-preventive grease.
• Not applicable: not provided in the available source.

3. Method principle

After a stoppered graduated cylinder containing rust-preventive oil or grease is successively subjected to specified alternating high-temperature, low-temperature, and room-temperature treatments according to the specified test cycle, observations are made, and the separation stability of the rust-preventive oil or grease is judged by whether phase change or separation occurs in the rust-preventive oil or grease in the stoppered graduated cylinder.

5. Instruments and equipment

• 3.1 Electrically heated constant-temperature water bath: capable of controlling the temperature at 55℃±2℃ (the temperature tolerance is unclear in the source transcription and remains unverified)
• 3.2 Electrically heated constant-temperature oven: capable of controlling the temperature at 110℃±2℃
• 3.3 Low-temperature chamber: capable of controlling the temperature at -20℃±2℃, with an effective internal height greater than the height of the 100mL stoppered graduated cylinder
• 3.4 Container: graduated 100mL stoppered graduated cylinder

6. Recommended operating conditions

• High-temperature water bath: 55℃±2℃
• High-temperature constant-temperature oven: 110℃±2℃
• Low-temperature chamber: -20℃±2℃
• Room temperature: 23℃±3℃
• For the specific standing times, see clause 8.

7. Sampling and specimen preparation

• Solvent-diluted rust-preventive oil: pour 50mL specimen into each of two 100mL stoppered graduated cylinders, and stopper them well.
• Rust-preventive grease: pour 50mL molten specimen into each of two 100mL stoppered graduated cylinders, and stopper them well.
• Human sweat displacement rust-preventive oil: pour 50mL specimen into each of four 100mL stoppered graduated cylinders, and stopper them well.

8. Analytical procedure

4.1 Solvent-diluted rust-preventive oil

• 4.1.1 Pour 50mL specimen into each of two 100mL stoppered graduated cylinders, and stopper them well.
• 4.1.2 Place the stoppered graduated cylinders in an electrically heated constant-temperature water bath, let stand at 55℃±2℃ for 8h, take out the stoppered graduated cylinders and place them in a low-temperature chamber, and let stand at -20℃±2℃ for 16h.
• 4.1.3 After carrying out the above operations four times, take out the stoppered graduated cylinders and place them indoors at 23℃±3℃ for 24h. Then invert the stoppered graduated cylinders for 5s, then place them in the original state for 5s, repeat this operation four times, then let stand for 1h, and then observe.

4.2 Rust-preventive grease

• 4.2.1 Pour 50mL molten specimen into each of two 100mL stoppered graduated cylinders, and stopper them well.
• 4.2.2 Place the stoppered graduated cylinders in an electrically heated constant-temperature oven at 110℃±2℃ and heat for 1.5h, take out the stoppered graduated cylinders and place them indoors at 23℃±3℃ for 1h, then transfer them to a low-temperature chamber at -20℃±2℃ and leave for 1h, then take out the stoppered graduated cylinders and place them in an electrically heated constant-temperature oven at 110℃±2℃ and heat for 1h. After the stoppered graduated cylinders have cooled to room temperature, observe.

4.3 Human sweat displacement rust-preventive oil

• 4.3.1 Pour 50mL specimen into each of four 100mL stoppered graduated cylinders, and stopper them well.
• 4.3.2 Place two stoppered graduated cylinders in a low-temperature chamber at -20℃±2℃ and let stand for 16h, take out the stoppered graduated cylinders and put them into an electrically heated constant-temperature water bath, and let stand at 55℃±2℃ for 8h.
• 4.3.3 After repeating the above steps three times, take out the stoppered graduated cylinders, cool them indoors to 23℃±3℃, and let stand for 24h.
• 4.3.4 While operating the two stoppered graduated cylinders of 4.3.2, place the other two stoppered graduated cylinders into an electrically heated constant-temperature water bath, let stand at 55℃±2℃ for 72h, take out the stoppered graduated cylinders and cool them indoors to 23℃±3℃, and let stand for 24h.
• 4.3.5 (the original text source-text extraction reads “4 1 F place V9 } - stoppered graduated cylinder inverted. then slowly f ib. m original. repeat this six times. then let stand 1h. and then observe.”, clause number and text require confirmation against the source standard (source-text extraction)): invert the stoppered graduated cylinder, then slowly restore it to the original state, repeat this six times, then let stand for 1h, and then observe.

9. Qualitative and quantitative determination and calculation formulas

Result judgment (Chapter 5):

• When neither of the two specimens has phase change or separation, it is judged as no phase change or no separation.
• If one of the specimens is confirmed to have phase change or separation, retest; if in the retest result one of the specimens is again confirmed to have phase change or separation, it is judged as having phase change or separation.
• Calculation formula: not provided in the available source.
