A quality assurance program of random sampling, testing and inspection, will be performed by a representative of the Materials Engineer, at each pipe plant operating under this program. The records file should be checked once a month, and a spot inspection by the Inspection Engineer should be done every six months. The manufacturer's testing, for the quality control program, may be conducted by the manufacturer's own qualified personnel, a professional engineer, or an independent inspection laboratory. Because the quality control program must be tailored to each individual plant, the schedule and testing rates may vary from plant to plant. The following is offered as guidelines for the sampling, testing and inspection of materials and finished products to be included in the quality control program.
