If you feel that your comments have not received a fair hearing you should make your views known to d611 ASTM Committee on Standards, at the address shown below. A number in parentheses indicates the year of last 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. Summary of Practice 4. Originally approved in asrm While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
An illustration of this can be made with the peel adhesion test. 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.
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. Last previous edition approved in as D — 89 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.
It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. Include no more sample rolls than will displace one fourth of the air volume in the vessel. 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. Use separators that allow free air space around and between the rolls and which are non-hygroscopic.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Appearance of normal tape product will usually change only slightly on two years natural aging.
The vessel must meet the following requirements: 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.
These small differences result in slightly different aging of the tape from time to time.
Unless otherwise indicated, it is intended that all reagents shall conform to the speci? Your comments are invited either for revision of this standard or for additional sstm and should be addressed to ASTM International Headquarters. Immediately remove the sample rolls from the assembly.
D36111 International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product. Current edition approved Oct. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
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. It is not intended for use on electrical grade tapes see Test Methods D It is superimposed on the variability inherent in performance of the subsequent physical property test for which this conditioning was preparatory.
ASTM D – 06() Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes
Satm environment in the vessel is dependent on careful observation of the requirements d6311 loading in relationship to vessel volume and liquid surface area in accordance with Section asym. This standard has been approved for use by agencies of the Department of Defense. This is like the variability in any test method that we commonly term its precision. This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product.
It is an effect due to the small differences that occur in performing any step of a process. This reduces salt deposition and crystalline build-up. 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: Aging reduces this inherent variability between specimens for some types of tape and some tests.
ASTM D3611 – 06(2011)
A different type of tape could yield data satm to more or less than that time period. 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 wstm the outside of the vessel can be balanced.
Therefore this c3611 does not always cause an increase in dispersion. It is the responsibility of the user of this standard to establish appropriate asmt and health practices and determine the applicability of regulatory limitations prior to use.
We do not expect this superimposed added variability effect to be great. 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. This variation does not appear as something we can measure directly on its own. 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.
This solution within the closed vessel both provides and controls the moisture content humidity within the vessel.
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. An abnormal product lot may cause aatm in testing response that throw off the expected time patterns.
