参考标准：EN166、EN168等等

测试目的：主要测试镜片的抗颗粒破坏性能，要求将镜片以一定速度旋转（250±10r/min），与一定量的石英砂（3kg）发生摩擦，进而观察镜片的受损情况。

测试方法：   

1.将镜片固定于仪器内的吸盘上； 

2.启动仪器，转动吸盘，使镜片以250±10r/min的速度旋转，将3kg石英砂从仪器顶部漏斗中倒入，使其慢慢漏完；   

3.关掉电源，取下镜片，观察镜片受损状况。

关键参数：

1. 导管长度：1650mm

2. 导管直径：120±3mm

3. 试样座角度：45±1°

4.  吸盘打转速度：250±10r/min

8. 重量:55 Kg9.

Reference standards: EN166, EN168, etc

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:

Set the lens to a suction cup in the instrument.

Start the instrument, rotate the suction disc, and rotate the lens at 250 + or 10r/min, and pour 3 kg of quartz sand from the top funnel of the instrument to drain it.

Turn off the power, remove the lens, and observe the damaged condition of the lens.
