Many times we can find a lot of chemical plastic barrel shadows in our lives. These chemical plastic barrels will appear in front of people after being tested by the staff. What are the testing standards?
1. Normal temperature drop experiment: Chemical plastic barrels have a nominal capacity of water, falling from a height of 0.8 meters without breaking.
2, normal temperature stacking experiment: chemical plastic barrels with a nominal capacity of water, stacking 2 high, no support on all sides, no leakage after 48 hours.
3, airtight test: pressure 200KPa constant pressure for 30 minutes chemical plastic barrel without leakage.
4, liquid-tight test: pressure 100KPa constant pressure for 30 minutes chemical plastic barrels without leakage.
5. Black spot impurities: ≤ 5 per 100 cm 2 surface, and the length is 0.5 cm.
