Quality Assurance Plan Product Name: Stone Ware Pipes

This quality assurance plan outlines the controls and checks for stoneware pipes. It details the raw materials used, production processes, and final inspections. Key points: - Raw materials (clay, salt, quartz, feldspar) are checked for characteristics like color and size upon arrival and samples are analyzed. - Production includes grogging, mixing, and firing, with checks on proportions, temperatures, and powder. - Final inspection tests pipes for dimensions, defects, hydraulic performance, absorption, acid/alkali resistance, strength, and marking compliance against standards. - Checks are conducted by the manufacturer and records are verified by a third-party inspection authority.
