In the drawn general purpose temper, the pipe shall be suitable for architectural applications, such as guard railings and stair hand railings. The chemical requirements for the specimen are as follows: copper, lead, iron, and zinc. The Specimen will undergo expansion test and the expanded pipe shall show no cracking or rupture visible to the unaided eye. It shall then undergo the mercurous nitrate test to examine if there are cracks. The material shall be passed through an eddy-current testing unit adjusted to provide information on the suitability of the material for the intended application. It shall then undergo the pneumatic test to for visual detection of any leakage, such as by having the material under water or by the pressured-differential method. The material shall be free of defects of a nature that interfere with normal commercial applications. It shall be well cleaned and free of dirt.
