Standard Specification for Dimensions and Tolerances for Plastic Bottles

Fecha:
2016-12-27 /Active
Abstract:

This specification covers the thread configuration and dimensions for finishes for plastic bottles with screw-type closures. The bottle overflow and body dimensional tolerances are detailed. The test apparatus for determining bottle capacity consists of a balance, pipet, graduated cylinder, beaker, conditioned water, and stop watch. In addition, the test apparatus for determining finish and body dimensions includes micrometers, Vernier height gages or Vernier calipers, internal micrometers or telescoping gages, and commercial scale. The test methods discussed are for the determination of bottle capacity, body dimensions, and finish dimensions.

Scope:

1.1 This specification covers the thread configuration and dimensions for finishes for plastic bottles with 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 for bottle capacity and body dimensions.

1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values 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 of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note 1: There is no known ISO equivalent to this standard.
