ASTM D4332 Package Conditioning

Testing Standard:

ASTM D4332 Practice for Conditioning Containers, Packages, or Packaging Components for Testing

Standard Number
ASTM D4332

Standard Title
Practice for Conditioning Containers, Packages, or Packaging Components for Testing

Overview for ASTM D4332:

ASTM D4332 is used to evaluate the ability of a package system to protect the inner product at different atmospheric conditions. Purple Diamond Testing offers ASTM D4332 Testing as part of our packaging compliance and validation services.

Rationale for ASTM D4332:

ASTM D4332 – Practice for Conditioning Containers, Packages, or Packaging Components for Testing. This test method is used in the production of packaging systems that will undergo changes in the physical properties over time depending on atmospheric conditions. Establishing a standard conditioning period prior to testing will ensure consistent test results amongst similar test samples and test locations, as well as testing to conditions a package may be exposed to in transit.

According to ASTM.org,

“Significance and Use

4.1 Many materials from which containers and packages are made, especially cellulosic materials, undergo changes in physical properties as the temperature and the relative humidity (RH) to which they are exposed are varied. Therefore, the package should be placed and kept in a specified atmosphere for a length of time such that subsequent measurements of physical properties will be meaningful and reproducible.

4.2 The conditions described in this practice are either historically accepted standard conditions or special laboratory conditions chosen to represent particular phases of the distribution environment. These special conditions do not necessarily duplicate actual field conditions, but tend to simulate them and have effects on packages and materials which may be related to their field performance.

Scope

1.1 This practice provides for standard and special conditioning and testing atmospheres that may be used to simulate particular field conditions that a container, package, or packaging component may encounter during its life or testing cycle.

1.2 This practice describes procedures for conditioning these containers, packages, or packaging components so that they approach or reach equilibrium with the atmosphere to which they may be exposed. This standard is commonly used for conditioning when conducting transit simulation tests.

1.3 Practice D685 should be used as the relevant conditioning standard when quantification of box compression strength at standard atmosphere conditions is required.

1.4 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.

1.5 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.”

The product packages travel to specific destinations, and when they do, they are exposed to a variety of environmental conditions such as temperature or humidity that may adversely affect the package systems. The actual purpose of ASTM D4332 is to realistically simulate the environments that products and their packaging will encounter during their transit route. One example of a transit route is that a product can be made and manufactured in California and then shipped to New York. During the trip from California to New York, the packaged product will encounter a variety of climates on its journey, which includes and is not limited to, the heat and humidity in the Midwestern states, freezing temperatures in the northern states, and also dryer conditions in the southwest. As you can see there are a few different temperature and air humidity ranges that these packaged products will go through. All of these specific environmental conditions will need to be simulated during the testing phase. This needs to happen in order to assess realistically how the packaging will withstand the real-life conditions during shipment.
