2. Scope of application and non-applicability

• This standard specifies the test method for packaging storage of rust-preventive oil and grease in a louvered box.
• This standard applies to rust-preventive oil and grease.
• Not applicable: not provided in the available source.

3. Method principle

Wrap a test specimen coated with the sample in wrapping paper, place it in a louvered box, and after the specified test time, inspect the rust-preventive performance of the oil film.

4. Reagents and materials (purity / preparation)

4.1 Reagents

• 5.1 Petroleum ether: analytical grade, boiling range (source-text extraction doubtful point, the source text has '[unreadable characters]0℃') requires confirmation against the source standard (source-text extraction).
• 5.2 Anhydrous ethanol: chemical grade.
• 5.3 Solvent naphtha: meets the requirements of SH 0004.

4.2 Materials

• 4.2.1 Metal test specimen: meets the requirements of SH/T 0218.
• 4.2.2 Absorbent cotton.
• 4.2.3 Abrasive cloth: grain size is 240 number (the source text has '24() number', requires confirmation against the source standard (source-text extraction)).
• 4.2.4 Wrapping paper: inner layer polyethylene film; outer layer kraft paper, specification is 100mm × 150mm (the source text has 'l00mm × 150mmo', requires confirmation against the source standard (source-text extraction)).
• 4.2.5 Transparent adhesive tape: width 10mm (the source text has 'lomma', requires confirmation against the source standard (source-text extraction)).

5. Instruments and equipment

• 4.1.1 Louvered box: made of high-quality wood, with a corrosion-resistant screen inside, a water tank on the inner bottom plate, and a test specimen rack; facing north with its back to the south, the distance from the bottom of the box to the ground should be no less than 800mm (the source text has '800nm m', requires confirmation against the source standard (source-text extraction)); the inner and outer walls and windows and doors of the louvered box should be painted white; the design of the louvered box should consider a position for installing meteorological measuring instruments. Its structure is shown in Figure 1.
  • 4.1.1.1 Screen: plastic screen, mesh opening is 3001 = (the source text is thus, requires confirmation against the source standard (source-text extraction)).
  • 4.1.1.2 Water tank: 685mm × 830mm × 130mm, made of corrosion-resistant material, wall thickness determined by ensuring sufficient strength.
  • 4.1.1.3 Test specimen rack: made of wood or plastic, structure as shown in the figure (the source text has 'as shown in to', requires confirmation against the source standard (source-text extraction)).
• 4.1.2 Electric furnace: 500W.
• 4.1.3 Beaker: 1000mL (the source text has 'IOOOmLo', requires confirmation against the source standard (source-text extraction)).

6. Recommended operating conditions

• The louvered box faces north with its back to the south, and the bottom of the box is no less than 800mm from the ground.
• The measurement surface of the test specimen faces south inside the louvered box.
• The water surface in the water tank is about 100mm from the lower end of the test specimen (the source text has 'l00}', requires confirmation against the source standard (source-text extraction)), and this water level is maintained until the end of the test.
• Test time: storage is carried out according to the test time specified in the product standard.

7. Sampling and specimen preparation

• 6.1 Preparation of test specimens: each sample requires three test specimens (the source text has '[garbled test-specimen quantity]', requires confirmation against the source standard (source-text extraction)); grind according to the provisions of SH/T 0218, use one side as the measurement surface, then clean and coat with the sample.
• 6.2 After the test specimen coated with the sample is drained according to the time specified in SH/T 0218, use the polyethylene film side of the wrapping paper as the inner side in contact with the measurement surface of the test specimen, and wrap it according to the method shown in Figure 2.

8. Analysis procedure

• 6.3 Place the wrapped test specimen on the test specimen rack inside the louvered box, with the measurement surface facing south.
• 6.4 Add water to the water tank inside the louvered box, with the water surface about 100mm from the lower end of the test specimen, and maintain this water level until the end of the test.
• 6.5 The test specimen is stored according to the test time specified in the product standard; after the test period expires, take it out, unwrap it, visually inspect and record changes such as cracks and peeling on the measurement surface.
• 6.6 Clean off the oil film on the surface of the test specimen with petroleum ether and solvent naphtha, dry the measurement surface, and rate according to the provisions of SH/T 0217.

9. Qualitative and quantitative and calculation formula

• Rate according to the provisions of SH/T 0217.
• Take the average corrosion degree of the three test specimens after the test ends, round to an integer, and then express it with the corresponding grade.
• Calculation formula: not provided in the available source.

10. Precision

Not provided in the available source.

11. Report

• Take the average corrosion degree of the three test specimens after the test ends, round to an integer, and then express it with the corresponding grade.
• In addition, when there are abnormal changes such as cracks and peeling in the oil film, record them.
