Statements will be included zstm each when the proper data have been obtained and analyzed. In cases of disagreement arising from differences in values reported by the owner and the manufacturer when using this test method for acceptance testing, the statistical bias, if any, between the laboratory of the owner and the laboratory of the manufacturer should be determined with each comparison being based on testing specimens randomly drawn from one pipe of the type being evaluated.
Cylinder specimens of sizes other than 6 by 12 in. Next, immerse the gasket completely in water and measure the mass of the gasket while totally submerged.
