參考标準：EN166、EN168等等測(cè)試目的：主要測(cè)試鏡片的抗顆粒破壞(huài)性能，要求将鏡片以一定速度旋轉（250±10r/min），與一定量的石英砂（3kg）發(fā)生摩擦，進而觀察鏡片的受損情況。測(cè)試方法 ： 1.将鏡(jìng)片固定於(yú)儀器内的吸盤上； 2.啓動(dòng)儀器，轉動(dòng)吸盤，使鏡(jìng)片以250±10r/min的速度旋轉，将3kg石英砂從(cóng)儀器頂(dǐng)部漏鬥中倒入，使其慢慢漏完； 3.關掉電(diàn)源，取下鏡片，觀察鏡片受損狀況。關鍵參(cān)數：1.導管長度：1650mm2.導管直徑：120±3mm3. 試樣座角度：45±1°4. 吸盤打轉速度 ：250±10r/min5. 網眼 ：1.6mm6.電源：AC100~240V 50/60Hz7.尺寸:46×47×227 CM(長×寬×高）8.重量:55 Kg
Reference standard: EN166 and EN168 test purposes: the main test lenses particle damage resistance, require that the lens at a certain speed rotation (250 + 10 r/min), with a certain amount of quartz sand (3 kg) friction, and then observe the lens for damage.Test method: 1. Fix the lens to the suction cup in the instrument;2. Start the instrument and rotate the suction cup to make the lens rotate at a speed of 250 plus or minus 10r/min, and the 3kg quartz sand is poured from the top funnel of the instrument to drain it slowly.3. Turn off the power, remove the lens, and observe the damage of the lens.Key parameters: 1. The pipe length: 1650 was. Vessel diameter: 120 + 3 mm3. Sample seat Angle: 45 + 1 ° 4. Chuck is spinning speed: 250 + 10 r/min5. Mesh: 1.6 mm6. Power supply: 50/60 AC100 ~ 240 v hz7. Size: 46 * 47 * 227 CM (length x width x height) 8. Weight: 55 Kg
