CPT REPORT Page Page 4 of 12,2 3 Personnel Assessment Standards. The following methods were used for evaluating the personnel skills and. competences, ASTM D4228 Standard practice for qualification of coating. applicators for application of coatings to steel surface. 3 TEST PANEL AND COATING MATERIALS,3 1 Test Panel, A test panel with size of 1m x 1m and containing of 2 pipe ends from two.
standing pipes 1 angle and 1 flat bar was used in the execution of CPT for. qualifying all the coating procedures This test panel has been approved by the. owner representative prior to its selection as well as was witnessed during. execution of CPT, Test Panel Before fabrication Test Panel After fabrication. 3 2 Coating Materials, Coating materials from a single source supplied by International Paints were used. for the CPT The coating system consisted of primer and top coat where both of. them are the same materials which is Interzone 954 Modified Epoxy except they. are differentiated by the color The primer is gray while the top coat is yellow. The primer is gray in color,Product code for Part A is. EAXN35 and EAA964 for,Part B Shelf life not exceed. expiration date Supplied,with valid batch certificate.
