檢測儀器:

                            PTT-03A厚度測試儀左.jpg

                                            PTT-03A測厚儀

檢測步驟:


1.試樣在(23士2)C條件下狀態調節至少1 h,對濕敏薄膜,狀態調節時間和環境應按被測材料的規范,或按供需雙方協商確定。

2.試樣和測量儀的各測量面(2.1)無油污、灰塵等污染。

3. 測量前應檢查測量儀零點,在每組試樣測量后應重新檢查其零點。

4.測量時應平緩放下測頭﹐避免試樣變形。

5.按等分試樣長度的方法以確定測量厚度的位置點,方法如下:

a>試樣長度≤300 mm,測10點﹔

b)試樣長度在300 mm 至 1 500 mm之間,測20點;c)試樣長度≥1 500 mm,至少測30點。

對未裁邊的樣品,應在距邊50 mm開始測量。
