3 Terms and definitions
The following terms and definitions apply to this standard. 3.1
Corrosion
Deterioration of a material caused by the reaction of a metal or material with the environment in which it is located. This deterioration is usually caused by oxidation, acid or alkali, electrochemical effects, etc. In the test, as long as there is a visible change on the surface of the test piece, such as rust, pitting, or the formation of loose or granular products, it is considered to be corrosion.
Disease
Corrosion of the material or reduction in performance.
Stain
Only a color change occurs on the test surface without rust, pitting or surface deterioration. This color change is not considered corrosion in this test. 3.4
Test surface
Specially processed material surface for checking corrosion status after the test. 3.5

Select according to the actual contents of the package. When not specifically specified, metal test pieces are generally selected from T3 pure copper plates that meet the GB/T2010 standard, pure aluminum plates that meet the GB/T3880 standard, galvanized passivation on steel, and pan-plated passivation on steel. Before the test, the copper and aluminum test pieces are alternately polished in vertical directions with 240 sandpaper. After polishing, the grinding marks on the test pieces should be parallel and consistent, and there should be no pits, scratches, or rust on the surface. There should be no burrs on the test pieces and the edges of the holes.
Plating or coating and other non-gold materials do not need to be processed or polished. Test pieces can be directly cut from dummy pieces or according to the test procedure size. For the prepared test pieces, except for materials that cannot contact ethanol, use tweezers to clamp the test pieces and absorbent cotton (gauze), wash them three times in three containers containing anhydrous ethanol in sequence, then blow dry with hot air, and test after cooling to room temperature. When it cannot be put into the test continuously, it should be placed in a dryer containing fine-porous silica gel, but it should be used within 8 hours, otherwise it should be re-polished and cleaned. 5.2 Test Specimens
Unless otherwise specified, the test samples of packaging materials should be selected at will, and there should be enough quantity to fully represent the materials being evaluated. 6 Test Procedure
6.1 Compatibility of Neutral Packaging Materials with Metal, Plastic or Other Solid Materials to be Packaged 6.1.1 When wrapping a metal or hard plastic test piece of size 100mm×50mm×(3~~5)mm with a 150mm×150mm neutral packaging material sample, the test surface should be double-layered near the longitudinal center line and single-layered on both sides. Then fold the two ends of the test piece in the length direction to the test surface, tie the folded layers tightly along the longitudinal direction of the test piece with nylon rope, and hang it in the exposure environment for the test. 6.1.2 Unless otherwise specified in the contract or order, the wrapped test piece should be hung vertically in a damp heat test chamber at 39°C±2°C and a relative humidity of not less than 95% for 72 hours, then taken out, unwrapped, and the deterioration of the test piece and packaging material sample should be checked and recorded. 2
GB/T 16265-2008
6.1.3 When corrosion is suspected on the copper test piece, drop a drop of prepared sodium azide iodine solution on the suspected area. The solution is prepared by dissolving 1.3g iodine and 4g potassium iodide in 100mL distilled water, and then adding 3g sodium azide to the solution. Many small bubbles will immediately appear on the liquid surface, indicating that there are sulfides on the sample, proving that the sample package is corroded. If observed with a 5x magnifying glass, the discontinuous bubbles generated slowly cannot prove the presence of sulfides. 6.2 Compatibility of gas phase anti-rust packaging materials with the packaged metal materials Unless otherwise specified in the contract or order, the test should be carried out three times in parallel according to the following method, and a blank (no gas phase anti-rust material) should be tested for comparison. 6.2.1 Flexible gas phase anti-rust packaging material
Cut a sample with a size of 200mm×60mm, and place the non-coated surface close to the upper inner wall of the specimen bottle. The test body is assembled as shown in Figure 1. Inject 25mL of 45% glycerol aqueous solution at the bottom of the specimen bottle. Place it in a drying oven at 65℃±2℃ for 2h to form a sealed space with an internal relative humidity of 85%±3%. Hang the test piece with a size of 75mm×13mm×1.5mm pretreated according to 5.1 in a specimen bottle placed in a drying oven at 65℃±2℃ for 2h, where the distance between the gas phase anti-rust packaging material sample and the packaged test piece does not exceed 30mm, and the lower end of the test piece is about 20mm away from the liquid surface of the glycerol aqueous solution. Cover the standard bottle cap and fix it with adhesive tape. Put the assembled specimen bottle in a constant temperature box at 60℃±2℃ and heat it continuously for 120h. Unless otherwise specified, take the standard sample bottle out of the drying oven after 120 hours, cool it to room temperature, open the sample bottle and check the test piece.

Place it in a drying oven at 65℃±2℃ and heat it continuously for 120h. Unless otherwise specified, take the specimen bottle out of the drying oven after 120h, cool it to room temperature, open the standard bottle and check the test piece. 6.3 Check the compatibility of gas phase anti-rust packaging materials and heat-sealed packaging materials 6.3.1 Flexible gas phase anti-rust packaging materials
Unless otherwise specified in the contract or order, the test should be carried out three times in parallel according to the following method, and neutral kraft paper should be used as a blank for comparative testing. Cut the heat-sealable packaging material into 254mm×130mm and fold it in half to form a pocket. Heat weld the two sides to make a pocket 127mm long. Wrap a steel test piece with a size of 100mm×50mm×（4~6）mm with gas phase rust prevention packaging material, and the side coated with gas phase corrosion inhibitor GB/T16265--2008
should face the steel test piece. When wrapping, the test piece should be double-layered near the longitudinal center line, and single-layered on both sides. Put the wrapped test piece into the bag, press out the air in the bag by hand, and heat-weld the opening of the bag. Place the prepared sample assembly in a drying oven at a temperature of 65℃±2C for 168h. After the sample cools to room temperature, cut open the welded side and take out the wrapped test piece. Check the deterioration of the heat-sealable packaging material. 6.3.2 Gas phase rust prevention agent
Unless otherwise specified, the test should be repeated three times in the following manner, and a blank sample without gas phase corrosion inhibitor should be used for comparison. In the compatibility test of vapor phase rust inhibitor with heat-sealed packaging materials, a steel test piece with a size of 100 mm × 50 mm × (4-6) mm is directly placed in the heat-sealed bag in 6.3.1, and 0.25 g ± 0.005 g of vapor phase corrosion inhibitor is evenly distributed on one surface of the test piece. Other test procedures 6.3. 1.
6.4 Compatibility of liquid, semi-liquid peelable plastics or coatings with protected solid materials such as metals or plastics 6.4.1 Test method
Pour the liquid or semi-liquid peelable plastic or coating sample into a clean sealable glass container. The height of the sample in the glass container is half the length of the test piece. Put a solid material such as a metal or hard plastic test piece with a size of 100mm×50mm×(3~5)mm vertically into a liquid or semi-liquid sample, so that half of the test surface of the test piece is exposed on the liquid surface, cover the glass container and seal it and place it at room temperature for 1 year or place it in an environment of 38℃±2℃ for 30d. 6.4.2 Check the deterioration of the test piece and sample after the test Check whether the metal is corroded, whether the plastic is softened, cracked, pooled, deformed, etc. Check whether the color of the liquid or semi-liquid peelable plastic has darkened, whether there are lumps, gelation, precipitation, separation or defects that affect the use. If necessary, the performance of the sample can be checked according to the specifications. 7 Result judgment
The test results of this standard are mainly compared with the blank sample of three parallel samples. As long as the test piece and the sample are not deteriorated, or the deteriorated ones are not heavier than the blank, they are compatible. If one piece is heavier than the blank, the test needs to be repeated. If more than two pieces are heavier than the blank or one piece is still heavier than the blank after repeated tests, they are incompatible.
