ASTM D1002, 金屬試片的黏著剪力強度測試
黏著強度與接合過程的條件有很大的關聯，因此在過程中的條件變化會導致從黏著強度測試得到的結果準確性有所變異，這是廠商在依照ASTM規範準備試片的責任。ASTM 規範指出”測試儀器必須依照Practices E 4的要求”，為了此測試，我們使用有50kN荷重元和粗糙鋸齒夾面30kN容量的機械式楔型夾置具的5569桌上型試驗機，此規範更進一步說明”測試試片的長軸需與夾置具中心線拉伸方向相符”，為了保證應力方向確實的與中心線方向一致，我們在夾置具中插入了墊片，理論上，此墊片會與試片結合或用機械式置入。
Instron's new Precision Series Manual Wedge Grips provide accurate, repeatable, reliable gripping for alignment-sensitive tensile testing applications, such as those governed by Nadcap maximum bending requirements. Capacities are 100 kN (22,000 lbf) and 250 kN (56,000 lbf) , and these grips can also be used for testing in compression with the proper adapters, and in temperatures ranging from -80 ⁰C (-112 ⁰F) to +250 ⁰C (+482⁰ F).

The strength of adhesive bonds depends greatly upon the conditions under which the bonding process is carried out and the testing for which is described in ASTM D 1002, Lap Shear Strength of Adhesively Bonded Metal Specimens. This report demonstrates the capabilities of the Instron test frame and software for testing in accorandance to this standard.
