10N.m不鏽鋼餐具拉扭試驗機
Stainless Steel Cutlery Tensile Torsion Tester
重要試驗:
→叉、匙、湯勺和鈍刀等不鏽鋼餐具的強度試驗。
→把不鏽鋼餐具試件平放在水平的平面上,手柄頸部的最高點朝上,按長度每一厘米施加7N的力或不計長度施加100N,受力時間保持10s,並測量試件受力點處所允許的永久變形。
→不鏽鋼餐具手柄連接的牢固性試驗:金屬手柄、陶瓷以外的非金屬手柄。
→不鏽鋼餐具拉力和扭轉試驗,在10N.m拉扭試驗機上進行,拉扭試驗要在同一試件上依次進行。
→不鏽鋼餐具拉力試驗:須保持10s,拉力載荷位180N或90N。
→不鏽鋼餐具扭轉試驗:手柄表面積小于37cm²,轉矩3.7N.m,保持時間10s;手柄表面積大于或等于37cm²,轉矩4.5N.m,扭矩保持10s。
重要參數:
→不鏽鋼餐具扭矩:10N.m。
→不鏽鋼餐具拉力:90N;180N。
→不鏽鋼餐具定扭矩試驗:3.7N.m;4.5N.m。
