| Item | Standard | Measuring Method |
|---|---|---|
| Peel Strength |
ASTM D3330 | Put a certain amount of lithium secondary battery electrolyte and Lead Tab in Al Pouch, store it at 80℃ for a certain time, and measure the peel strength of the film with a tensile tester |
| Air Tightness |
KS B 0816 | Penetration detection test with the penetrants in the Lead Tab and check the color change with naked eye or microscope |
| Bend Test | KS B 0804 | Bending test with 180° of angle |
| Salt Water Spray |
S C IEC 60068-2-11 | Spray 5% NaCl aqueous solution at a certain interval under 35℃ conditions, store it for 24 hours, and check the surface condition. |
| Scribe-Grid Test |
ASTM B571 97 | Scratch the metal surface with three or more rectangular grid with strong tool, and attach a special tape, and then check if coating particles get on the tape when detached. |
| Visual Inspection |
. | Check the product surface for defects such as chipping, deformation, contamination, rust, scratch, etc. with visual or microscope |
| Dimension | Drawing | Check using Vernier calipers or three-dimensional measuring instruments with reference to the dimensions indicated in the design drawing |
