ASTM D – 06() Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes

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.

The vessel must meet the following requirements: Appearance of normal tape product will usually change only slightly on two years natural aging.

This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product. This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product.

A different type of tape could yield data comparable to more or less than that time period. While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.

This variation does not appear as something we can measure directly on its own. Current edition approved Oct. 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 s3611.

A superscript epsilon e indicates an editorial change since the last revision or reapproval.

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 an effect due to the small differences that occur in performing any step of a process. 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.

For example, a given type of tape a speci?

Last previous edition approved in as D — 89 This means that a measurement of precision for a physical property test on tape always has as one of its components the inherent variability between tape specimens. We do not expect qstm superimposed added variability effect to be great.

NOTE 1—The environment r3611 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. Natural astn 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.

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 solution within the closed vessel both provides and controls the moisture content humidity within the vessel. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any asm mentioned in this standard.

Immediately remove the sample rolls from the assembly. It is not intended for use on electrical grade tapes see Test Methods D 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 adtm.

Include no more sample rolls than will displace one fourth of the air volume in the chamber Include no more sample rolls than will displace one fourth of the air volume in the vessel. Aging reduces this inherent d36611 between specimens for some c3611 of tape and some tests.

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. Asym 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 Originally approved in It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. There is no present experience to relate this accelerated exposure to responses of tape in applications where the tape is under a use stress.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Therefore this conditioning does not always cause an increase in dispersion.
