D Terminology of Packaging and Distribution Environments.
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 an effect due to the small differences that occur in performing any step of a process.

It is superimposed on the variability inherent in performance of the subsequent physical property test for which this conditioning was preparatory. It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. Historical Version s – view previous versions of standard. This may require 24 or 48 h for some materials. While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.
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.
Last previous edition approved in as D — 89 An illustration of this can be made with the peel adhesion test. It is not intended for use on electrical grade tapes see Test Methods D 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. 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.
The vessel must meet the following requirements: Therefore this conditioning does not always cause an increase in dispersion. This is like the variability in any test method that we commonly term its precision. We do not expect this superimposed added variability effect to be great.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. For example, a given type of tape a speci?
Originally approved in This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions d33611 in abnormal product.
ASTM D3611 – 06(2011)
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. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. 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.
While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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.
This standard has been approved for use astmm agencies of the Department of Defense. 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. Include no more sample rolls than will displace one fourth of the air volume in the vessel.
A different type of tape could yield data comparable to more or less than that time period. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or d36111 phonefaxor service astm. 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.
An abnormal product lot may cause differences in testing response that throw off the expected time patterns. Include no more sample rolls than will displace one fourth of the air volume in the chamber This atsm 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. Reagents for Humidity Vessel in Oven procedure 7.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Immediately remove the sample rolls from the assembly. 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. Link to Active This link will always route to the current Active version of the standard.
Unless otherwise indicated, it is intended that all reagents shall conform to the speci?
These small differences result in slightly different aging of the tape from time to time. 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: Current edition approved Oct. The extent of change for one physical property should be expected to be different than for another property and so would also relate to d311 natural aging time.
This variation does not appear as something we can measure directly on its own. A number in parentheses d3161 the year of last reapproval. The environment in the vessel is dependent on careful observation of the requirements of d6311 in relationship to vessel volume asm liquid surface area in accordance with Section 7. This reduces salt deposition and crystalline build-up. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
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. Appearance of normal tape product will usually change only slightly on two years natural aging. It is not intended for use on electrical grade tapes see Test Methods D
