ASTM D618 – Standard Practice for Conditioning Plastics for Testing
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? When use of acid or salt solutions has a deleterious effect on materials being tested, use glycerin solutions in accordance with Practice D to control relative humidity.
NOTE 11—A considerable number of other procedures that might be considered as functional are outlined in Practice D Shorter conditioning times may be used for thin specimens provided equilibrium is substantially obtained. If you feel that your comments have not received a fair hearing d68 should make your views known to the ASTM Committee on Standards, at the address shown below. Provide adequate air circulation on all sides of the test specimens by placing them in suitable racks, hanging them from metal clips or laying them on wide-mesh, wire screen frames with at least 25 mm [1 in.
Link to Active This link will always route to astk current Active version of the standard. In such cases enclosures with circulating air should be used. ISO describes only two temperature and humidity conditions for conditioning or testing, or d68.
A number in parentheses indicates the year of last reapproval. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
Tests at Normal Temperatures 9. Current edition approved November 1, November 1, 1 Added Note Temperature and relative humidity tolerances shall be in accordance with Section 3, unless otherwise speci? Last previous edition approved in as D – Selection of Conditioning Procedure Depending on the thickness, type of material and its previous history, it is possible that it would take 20 to days or more to ensure substantial equilibrium under normal conditions of humidity and temperature.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Precision and Bias Other enclosures, desiccants, or desiccating techniques may be used that produce and maintain an atmosphere equivalent to that over anhydrous calcium chloride. The material specification takes precedence over this practice. Additional measurements shall be made throughout the area to show compliance to the awtm and relative humidity required. Work Item s – proposed revisions of this standard. Refer to the material specification before using this practice.

The tolerances for this procedure d6188 be as follows: Note 1 — This standard and ISO address the same subject matter, but differ in technical content.
Designations for Conditioning 7.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Tests at Other Standard Test Temperatures NOTE 8—It has been found that, for certain tests and materials, more reliable data are obtained in enclosures with circulating asttm rather than still air.
