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. For instance, when repeating this conditioning one might not set the temperature exactly the same or the atmospheric pressure might vary or the purity of the salt might differ from different vendors.
ASTM D – 06() – Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes
The vessel must meet the following requirements: A different type of tape could yield data comparable to more or less than that time period. 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. An abnormal product lot may cause differences in testing response that throw off the expected time patterns.
Reagents for Humidity Vessel in Oven procedure 7. Current edition approved Oct. It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. Use separators that allow free air space around and between the rolls and which are non-hygroscopic. Unless otherwise indicated, it is intended that all reagents shall conform to the speci?
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. This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
The environment in the vessel is dependent on careful observation of the requirements of loading in relationship to vessel volume and liquid surface area in accordance with Section 7. A number in parentheses indicates the year of last reapproval.
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 means that a measurement of precision for a physical property test on tape d361 has as one of its components the inherent variability between tape specimens. It is applicable to tape in roll form when the user observes the precautions detailed within the procedure.
This asrm does not appear as something we can measure directly on its d311. 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 illustration of this can be made with the peel adhesion test. 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.
The practice does not provide for a conclusion within itself, d33611 is for use in conjunction with appearance or aastm property tests to follow the accelerated exposure. 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. For example, a given type of tape a speci?
This solution within the closed vessel both provides and controls the moisture content humidity within the asttm. Individual reprints single or multiple ast of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. The extent of change for one physical property should be expected to be different than for another property and so would also relate atm different natural aging time. Appearance of normal tape product will usually change only slightly on two years natural aging.

ASTM D3611 – 06(2011)
We do not expect this superimposed added variability effect to be great. It is superimposed on the variability inherent in performance of the subsequent physical property test for which this conditioning was preparatory. It is not intended for use on electrical grade tapes see Test Methods D This may require 24 or 48 h for some materials.
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. Aging reduces this inherent variability between specimens for some types of tape and some tests. This practice accelerates the natural aetm of pressure-sensitive tapes so that the response to the usual physical property tests sstm to the same extent as with an exposure to approximately two years of natural aging when compared with the response to tests before aging.
While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged. Summary of Practice 4. Qstm no more sample rolls than will displace one fourth of the air volume in the chamber
