If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, 3d611 the address shown below.
Include no more sample rolls than will displace one fourth of the air volume in the chamber 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 asttm. Historical Version s – view previous versions of standard. Your comments are invited either for revision of this standard dd3611 for additional standards and should be addressed to ASTM International Headquarters.
ASTM D – 06() Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes
For example, a given type of tape a speci? Your comments will receive careful asmt at a meeting of satm responsible technical committee, which you may attend. 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.

ASTM D3611 – 06(2011)
It is not intended for use on electrical grade tapes see Test Methods D We do not expect this superimposed added variability effect to be great. Current edition approved Oct. This is like the variability in any test method that we commonly term its precision. The vessel must meet the following requirements: 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.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. 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 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 an exposure to approximately two years of natural aging when compared with the response to tests before aging.
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. 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. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
An illustration of this can be made with the peel adhesion test. Immediately remove the sample rolls from the assembly. 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. An abnormal product lot may cause differences in testing response that throw off the expected time patterns. It is applicable to tape in roll form when the user observes the precautions detailed within the procedure.
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. While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged. It is not intended for use on electrical grade tapes see Test Methods D There is no present experience to relate this accelerated exposure to responses of tape in applications where the tape is under a use stress.
It is applicable to tape in roll form when the user observes the precautions detailed within the procedure.
This variation does not appear as something we can measure directly on its own. This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product. For instance, when repeating this conditioning one might x3611 set the temperature exactly the same or the atmospheric pressure might vary or the purity of the salt might differ from different vendors.
While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.
This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product. S3611 standard has been approved for use by agencies of the Department of Defense.
Aging reduces this inherent variability between specimens for some types of tape and some tests. Summary of Practice 4.
