For certain types of materials having creep and recovery, the time factors involved in applications of major and minor loads have a considerable effect on the results of d785-008 measurements. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Please first verify your email before subscribing to alerts.
Each Rockwell hardness scale in Table 1 is an extension of the proceeding less severe scale, and while there is some overlap between adjacent scales, a correlation table is not desirable. Please first log in with a verified email before subscribing to alerts. The higher the number in each scale, the harder the material. Readings on one material may be satisfactory for such a table, but there is no guarantee that other plastic materials will give corresponding readings because of differences in elasticity, creep, and shear characteristics.
