4、s standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Significance and Use2.1 This test method provides a practical means to assess thestrength of glass pipe under internal positive hydrostaticpressure.Since test pr
5、essures are twice-rated values,the testrepresents a stringent evaluation of product strength.3.Apparatus3.1 The apparatus,as illustrated in Fig.1,shall be capable ofthe following:3.1.1 So designed that it can produce a regulated loadingrate of 3 psi(21 kPa)/s.3.1.2 So designed that it can produce hy
6、drostatic pressureup to 500 psi(3.4 MPa).3.1.3 Pipe-end seals and connections to testing apparatusshall be made as shown in Fig.2.4.Sampling4.1 A random sampling of12to 1%(but not less than twopieces)of each size of pipe and fittings shall be made.5.Procedure5.1 Cap the pipe as illustrated in Fig.2,
7、using standardfittings and inserts with blind flanges as end caps.Specify thebolt torque.5.2 Fill the pipe entirely with liquid,with no entrapped air,and place behind a protective shield.Keep both pipe and liquidat room temperature before testing.Use a torsion wrench totighten nuts in stages uniform
