ULc-S101 on Oriented Strand Board (OSB) “Fire Resistance Test”
This test is designed to run to 15 minutes but we ran it to just over 25 minutes delivering results better than any the laboratory technicians had ever seen from any intumescent product.
This was a full scale test using two sizes of beams and decking with 4” of concrete. The concrete was placed in segmented panels with a 1” gap to avoid the supportive effect that would happen with one contiguous pour. It was then loaded with an additional 1038 lbs/lf using hydraulic jacks. The test went to 174 minutes restrained for the lighter beams and decking and 176 minutes for the heavier section.
我们使用有史以来最薄的欧松板进行样本测试，其油漆膜厚度也是有史以来最薄的(8 mils 密耳),仍然得到5×40的燃烧等级和产烟级。
