Include no more sample rolls than will displace one fourth of the air volume in the chamber For example, a given type of tape a speci? This practice accelerates the natural aging of pressure-sensitive tapes so that the response to the usual physical property tests changes to the same extent as with ashm exposure to approximately two years of natural aging when d36111 with the response to tests before aging.
The practice does not provide for a conclusion within itself, but is for use in conjunction with appearance or physical property tests to follow the accelerated exposure.
Unless otherwise indicated, it is intended that all reagents shall conform to the speci? Summary of Practice 4.
ASTM D3611 – 06(2011)
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The extent of change for one physical property should be expected to be different than for another property and so would also relate to different natural aging time.
It is the responsibility of the user zstm this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.
Since it is seen as a change in the apparent variability of the physical property test results, we can relate it to the expected precision of the test by making the following statement: It is applicable to tape in roll form when the user observes the precautions detailed within the procedure.
ASTM D – 89() Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes
D Terminology of Packaging and Distribution Environments. These small differences result in slightly different aging of the tape from time to time. This standard has been approved for use by agencies of the Department of Defense.
This solution within the closed vessel both provides and controls the moisture content humidity within the vessel. Therefore this conditioning does not qstm cause an increase in dispersion. A different type of tape could yield data comparable to more or less than that time period.
The practice does not provide for a conclusion within itself, but is for use in conjunction with appearance or physical property tests to follow the accelerated exposure. An illustration of this can be made with the peel adhesion test.
We do not expect this superimposed added variability effect to be great. Natural aging in this context means a continuous period of aging of tape in a closed fibreboard container in darkness in the variable climate of either the warm moist south, the warm dry southwest or the moderate midcontinent, USA.
Last previous edition approved in as D — 89 A superscript epsilon e indicates an editorial change since the last revision or reapproval. This may require 24 or 48 h for some materials.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. An abnormal product lot may cause differences in testing response that throw off the expected time patterns. It is superimposed on the variability inherent in performance of the subsequent physical property test for which this conditioning was preparatory.
A number in parentheses indicates the year of last reapproval. Link to Active This link will always route to the current Active version of the standard. This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product. There is no present experience to relate this accelerated exposure to responses of tape in applications where the tape is under a use stress. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
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. Aging reduces this inherent variability between specimens for some types of tape and some tests. Use a volume the units will be cubic centimetres of water not less than that obtained by multiplying times times the vessel air volume in cubic metres. Appearance of normal tape product will usually change only slightly on two years natural aging.
Current edition approved Oct. This reduces salt deposition and crystalline build-up. NOTE 1—The environment for this practice cannot occur unless the vessel used as the environment container is vented so that pressure differences between the inside and the outside of the vessel can be balanced.
