ASTM D1654、ASTM B117-97； 35℃，5％ NaCl， spray 96hr， with adhesion test and cosmetic check.
test environment: temperature 20± 2℃,humidity 55± 5% tape speed:1 second 50mm,60second 3000mm. fixed load:RCA system 175gf,3 second ON/1 second OFF. Special paper tape:broad #60 cloth. Leave test samples under 25° for 24 hrs. Make the cross-cut scratch C the paint surface by cutter. Stick a specified tape (3M Scotch 610) on the scratched area completely (release all air out). Within 90± 30s of application,remove the type by seizing the free end and rapidly(not jerked) back upon itself at as close to an angle of 180° possible, moer as than 3 times.
Use a fluorescent UV/condensation Apparatus to test a specimen for 100 hrs and then check the film condition.Please refer to ASTM D4587,TABLE1,NO:4.
Comply with the rules/regulations: RoHS.
