API 936

Refractory Installation Quality Control—Inspection and Testing Monolithic Refractory Linings and Materials

API - 936 This standard provides installation quality control procedures for monolithic refractory linings and may be used to supplement owner specifications. Materials,equipment, and personnel are qualified by the methods described, and applied refractory quality is closely monitored, based on defined procedures and acceptance criteria. The responsibilities of inspection personnel who monitor and direct the quality control process are also defined. In addition, this standard provides guidance for the establishment of quality control elements necessary to achieve the defined requirements.
