全自動低溫柔度試驗儀中英文試驗步驟
試驗步驟：Test steps
試驗的矩形試件尺寸（150±1）mm×（25±1）mm,試件從試樣寬度方向上均勻的裁取,長邊在卷材的縱向，試件裁取時應(yīng)距邊緣不少于150mm,試件應(yīng)從卷材的一邊開始做連續(xù)的記號，同時標(biāo)記卷材的上表面和下表面。
Test of rectangular specimen size (150 + 1) mm x (25 + 1) mm, uniform cropping specimens from the sample width, long edge in vertical coil, specimen cropping should be away from the edge of not less than 150 mm, specimen from one side of the coil began to make a continuous mark, mark coil on the surface and under surface at the same time
去除表面的任何保護膜，適宜的方法是常溫下用膠帶粘在上面，冷卻到接近假設(shè)的冷彎溫度，然后從試件上撕去膠帶，另一方法是用壓縮空氣吹[壓力約0。5Mpa(5bar),噴嘴直徑約0。5mm]，假若上面的方法不能除去保護膜，用火焰烤，用zui少的時間破壞膜而不損傷試件。
Remove any protective film on the surface, the appropriate method is room temperature use sticky tape on it, cold bending temperature cooled to near hypothesis, and then removing the tape from the specimen, another method is to use compressed air to blow [pressure about 0. 5 mpa (5 bar), nozzle diameter 0. 5 mm], if the above methods can't remove the protective film, roasted with fire, destruction of membrane with the least amount of time without damage to the specimen.
試件試驗前應(yīng)在（23±2）℃平板上放置至少4h,并且相互之間不能接觸，也不能粘在板上?？梢杂霉杓垑|，表面的松散顆粒用手輕輕敲打除去。
Specimens should be in before the test (23 + 2) ℃ tablet placed at least 4 h, and can't contact with each other, also can't stick on the board. Can use silicon paper pad, loose particles on the surface of the knock gently to remove by hand
