ASTM E171

This specification defines the standard temperature and humidity for conditioning and testing of materials at nominally ambient conditions. Materials for conditioning and testing include material containing paper and plastic material. The instruments and techniques used to measure these standard conditions of temperature and humidity must be validated.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification defines the standard temperature and humidity for conditioning and testing of materials at nominally ambient conditions.

1.2 There are many other temperature and humidity conditions which may be appropriately used to test end use conditions such as freezer, refrigerated or abusive storage. These need to be individually established.

1.3 Temperature and humidity alone are not sufficient to completely define a storage condition. Many other factors may be relevant (such as time, light and atmospheric pressure) which are not defined in this specification.

1.4 Only those materials which fall into the general area of flexible packaging materials are included. Many other materials which were included in earlier versions of this specification may also need a definition.
