ASTM D4332 PDF

This standard simulates particular field conditions that are encountered at different stages of the distribution environment of the material. More specifically, this method describes a procedure which allows to properly condition the packages before they undergo the actual testing. For instance, this test can be used to condition packages before they are subjected to the ASTM D method. Indeed, this is due to the fact that this standard can provide special standard conditions. However, this method differs from ISTA testing because it only supplies the atmospheric conditions while the ISTA tests specifies the procedure to assess a particular property and those conditions as well.

Conditioning containers, packages, or packaging components for testing — use and factors to be considered: The goal of ASTM D is to provide the guidelines required to generate a conditioning atmosphere that may be used to assess the changes of physical properties of the samples in a reproductible manner.

Indeed, by exposing the sample to an environment of controlled temperature and relative humidity for a specific period of time, it is possible to evaluate the changes in physical properties that occur in the material when it is exposed to a different temperature and relative humidity.

In order to appraise the changes in the physical attributes, it is necessary to pair this method with a standard that assess the desired property. Lastly, it is important to keep in mind the simulation do not necessarily duplicate actual field conditions The main factors that are in play when conducting this test protocol are: the time of exposure, the temperature and the relative humidity.

Typical Experimental parameters for ASTM D testing: The number of samples has to be specified and their size must be the same as in the actual distribution. Table 1 lists the typical atmospheric conditions of this method and other type of atmosphere are available in table 1 and 2 of the ASTM D standard. Table I: Specification of the typical type of atmosphere of the standard Parameters.

ASTM D4332

ASTM D Standard Practice for Conditioning Containers, Packages, or Packaging Components for Testing 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. 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. 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.
