All PCCP manufacturers should establish quality assurance departments within the pipe plant to provide step-by-step attention to all production procedures and assure that all machinery and equipment is operating properly. Incoming raw materials must be carefully inspected and tested for compliance with the governing standards.
The AWWAC301 standard contains the testing methods to be used and acceptance criteria for all raw materials to be incorporated into the pipe and fittings.
