2.尖點(diǎn)測(cè)試程序
a.樣品在進(jìn)行尖點(diǎn)測(cè)試前須在室溫為23±2℃、濕度為20%～70%的環(huán)境內(nèi)放置4小時(shí)。
b.將放入尖點(diǎn)測(cè)試器測(cè)量槽內(nèi)/握住測(cè)試物/垂直自由的施加共重1LBS（4.5N）的力，通過(guò)測(cè)試量槽位至測(cè)試。
判定：測(cè)試燈亮則為不合格

操作原理：試驗(yàn)器有槽端有一寬0.04英寸長(zhǎng)0.045英寸的矩形開(kāi)口, 兩個(gè)參考尺寸尖銳度由被測(cè)該口的深度為0.015英寸深處的傳感頭, 并能克服彈力為0.5磅的彈簧使傳感頭再移動(dòng)0.005英寸, 即被確認(rèn)為尖銳點(diǎn). 要求：槽開(kāi)口不大于0.040×0.045英寸, 觸及深度不小于0.015英寸, 作用力不過(guò)1磅.：
Operating principle: the tester with a grooved end has a width of 0.04 inches long and 0.045 inches rectangular openings, two reference dimensions sharpness of a measured tip is inserted into the mouth of the depth sensing head 0.015 inches deep, and can overcome the elastic force of spring 0.5 pounds of the sensing head to move 0.005 inches, which is confirmed as the sharp. Requirements: slot opening is not greater than 0.040 x 0.045 inches, touch the depth of not less than 0.015 inches, force does not exceed 1 pounds:
