ASTM D2911/D2911M-16(2023)

Standard Specification for Dimensions and Tolerances for Plastic Bottles

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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: There is no known ISO equivalent to this standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM D2911/D2911M-16(2023), published by ASTM International, is the standard specification addressing dimensions and tolerances for plastic bottles with screw-type closures. The standard covers requirements for thread configuration, finish dimensions, and tolerances for body and overflow capacity for bottles up to 18.9 liters (5 gallons) with a maximum dimension of 305 mm (12 inches). Key to quality assurance in packaging, the specification ensures consistency and compatibility among plastic bottles and their closures.

The document also describes the precise test apparatus and methods for determining bottle capacity and verifying dimensional compliance, which is essential for manufacturers, designers, and participants in the plastic packaging supply chain.

Key Topics

• Thread Configuration and Finish Dimensions: Defines the neck and thread details for bottles intended to use screw-type closures, promoting closure compatibility and leak prevention.
• Body and Overflow Capacity Tolerances: Outlines recommended variations for bottle capacity and external body dimensions, ensuring each product falls within predictable quality and performance specifications.
• Test Methods for Plastic Bottles:
  • Capacity determination using specified laboratory equipment (balance, pipet, graduated cylinder, beaker, conditioned water, stop watch).
  • Dimensional verification utilizing micrometers, Vernier calipers, height gauges, and internal measuring devices.
• Units of Measurement: Details the use of both SI and inch-pound units, with a requirement that values from each measurement system are not to be combined for conformity.
• Sampling and Conditioning: Establishes procedures for batch sampling and environmental conditioning to achieve representative and repeatable results.
• Retest and Rejection Procedures: Provides guidance on retesting and dispute resolution when initial measurements do not meet requirements.

Applications

ASTM D2911/D2911M-16(2023) is essential across various sectors involved in plastic packaging, including:

• Beverage and Food Packaging: Manufacturers require consistent bottle dimensions for seamless closure application and secure product storage.
• Pharmaceuticals and Cosmetics: Ensures bottles provide reliable seals, critical for product safety, shelf life, and regulatory compliance.
• Household and Industrial Chemicals: Standardized bottle finishes support automation, prevent leakage, and minimize waste during storage and transportation.
• Bottle and Closure Design: Facilitates design compatibility, interchangeability, and supply chain efficiency for manufacturers of bottles and closures.
• Quality Assurance and Inspection: Provides clear, testable criteria for incoming inspection and process control in bottle production.

Adopting this standard reduces the risk of closure failures, product waste, and customer complaints by ensuring that plastic bottles consistently meet industry-accepted design and dimensional requirements.

Related Standards

For comprehensive quality control and full lifecycle management of plastic bottles, the following standards are also relevant:

• ASTM D618 - Standard Practice for Conditioning Plastics for Testing: Establishes environmental and timing requirements for pre-conditioning plastics prior to testing.
• Formerly ASTM D1898 - Practice for Sampling of Plastics: Provided guidance for the statistical sampling of plastics, referenced for batch acceptance procedures.
• ASTM D7611 - Standard Practice for Coding Plastic Manufactured Articles for Resin Identification: Useful for tracing resin materials used in bottle production.

Note: There is no known ISO equivalent for ASTM D2911/D2911M-16(2023), reinforcing its unique relevance in the North American plastic packaging sector.

Compliance with ASTM D2911/D2911M-16(2023) helps ensure that plastic bottles are standardized, compatible, and reliable, supporting safe and efficient packaging operations across industries.

Concentricity of I min with respect to diameters T and E is not included. I min is specified for filler tube only.
NOTE 1—Constriction of neck from B to D must be held within the shaded area shown.
NOTE 2—A minimum of 1 ⁄8 turns of thread shall be maintained.
NOTE 3—Consideration must be given to the sealing surface width for the sealing system being used.
NOTE 4—When valve style closures are used with this finish, special consideration must be given to a specific controlled inside diameter. In addition,
it is acceptable to vary the dimensions indicated with asterisk (*) to ensure adequate material for finishing the inside diameter.

NOTE 1—This finish drawing was established by PBI to provide plastic bottle finishes comparable to 445, 450, and 480 glass finishes.
NOTE 2—Dimension H is measured from top of the finish to the point where diameter T, extended parallel to the centerline, intersects the shoulder
or bead.
NOTE 3—A minimum of 1 ⁄8 turns of thread shall be maintained.
NOTE 4—Contour of bead, undercut, or shoulder is optional.
NOTE 5—Unless otherwise specified. I min applies to the full length of the opening.
NOTE 6—Concentricity of I min with respect to diameters and T and E is not included. I min is specified for filler tube only.
NOTE 7—T and E dimensions are the average of two measurements across the major and minor axis. The limits of ovality will be determined by the
container supplier and container customer, as necessary.
NOTE 8—Consideration must be given to the sealing surface width for the sealing system being used.
NOTE 9—When valve style closures are used with this finish, special consideration must be given to a specific controlled inside diameter. In addition,
it is acceptable to vary the dimensions indicated with asterisk (*) to ensure adequate material for finishing the inside diameter.
