Scope Scope*1.1 This specification covers the thread configuration and dimensions for finishes for plastic bottles wit
3、h screw-type closures,having a maximum capacity of 18.9 L (5 gal) and a maximum bottle dimension of 305 mm (12 in.). Included are tolerances forbottle capacity and body dimensions.1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded as the separately as standard. The
4、valuesstated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combiningvalues from the two systems may result in non-conformance with the standard.1.3 The following precautionary caveat pertains only to the test methods portion, Section 8
