This may optionally be followed by a dash and the last two digits of the year in which the standard was adopted. From basic tension and compression testing to advanced materials testing the DSTM-5kN is a versatile test system used across virtually all industries. A nylon counter plate is placed on the bottom arm and the cutting die is placed on the top. The articles are exposed to gaseous fluorine in a reactor vessel under reaction conditions sufficient to reduce the friction coefficient and improve the wear life, without promoting degradation of the tensile properties of the article. ASTM D638 or D1708 : Elongation (at either break or yield as applicable) ASTM D638 or D1708 : Modulus of elasticity .
