ASTM D4991 -Standard Testing Instruments

Introduction

The ASTM D4991-07 (2015) standards describes a procedure for testing the ability of empty rigid containers to resist leaking through the use of a vacuum testing method. Liquid packaging containers must maintain the integrity of their structure under pressure or vacuum conditions during shipping, storing and handling. This standard defines an effective way of identifying leaks by placing the test containers into a vacuum chamber and subjecting them to different amounts of air pressure within the chamber. Any loss of air or fluid will be easily seen. The use of ASTM D4991-07 (2015) assists a manufacturer in evaluating the performance of their packaging system to determine if they are capable of withstanding rigorous distribution requirements.

 

ASTM D4991

 
Significance
 
ASTM D4991-07 (2015) is key to the packaging industry because if a liquid (container) leaks it could potentially result in product loss, contamination, safety hazards and regulatory issues. Liquids that are transported (e.g., hazardous and/or fragile) in containers must be securely packaged to avoid leakage regardless of the atmospheric conditions that cause them to leak, including airborne transport. The standard includes a uniform, reproducible evaluation method of closure integrity and container performance.
 
Presto Stantest offers advanced vacuum leak testing solutions that help manufacturers verify packaging quality and identify defects before products reach the market. The test results support quality assurance programs, packaging development, and compliance with transportation requirements while helping manufacturers maintain product safety and reliability.
 
Scope
 
ASTM D4991-07 (2015) covers the leakage testing of empty rigid containers under vacuum induced differential pressure conditions. The standard is suitable for evaluating containers intended for the transportation of liquids and determining the point at which leakage begins. It applies to packaging manufacturers, testing laboratories, chemical companies, pharmaceutical industries, and quality assurance teams involved in package performance evaluation and verification.
