1.1 This test method describes a shop or field procedure for determination of roughness characteristics of surfaces prepared for painting by abrasive blasting. The procedure uses a portable skidded or non-skidded stylus profile tracing instrument. The measured characteristics are: Rt and Rpc. Additional measures of profile height (Rmax and/or Rz) may also be obtained as agreed upon by purchaser and seller. (The digitally-determined profile parameters Rt, Rmax, Ry and Rzlmax are extremely similar in definition.)
