The vessel must meet the following requirements: It is not intended for use on electrical grade tapes see Test Methods D Historical Version s – view previous versions of standard. 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.
Summary of Practice 4. 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 an effect due to the small differences that occur in performing any step of a process. Last previous edition approved in as D — 89 Aging reduces this s3611 variability between specimens for some types of tape and some tests.

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 qstm of natural aging when compared with the response to tests before aging. An illustration of this can be made with the peel adhesion test. It is applicable to tape in roll form when the user observes the precautions detailed within the procedure.
Immediately remove the sample rolls from the assembly. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
This reduces salt deposition and crystalline build-up. 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.
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. A superscript epsilon e indicates an editorial change since the asstm revision or reapproval. Appearance of normal tape product will usually change only slightly on two years natural aging.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to Asrm International Headquarters. An abnormal product lot may cause differences in testing response that throw off the expected time patterns.
ASTM D3611 – 06(2011)
This variation does not appear as something we can measure directly on its own. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Since it is seen as a change in the apparent variability of the physical property asym results, we can relate it to the expected precision of the test by making the following statement: Use separators s3611 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. 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 astmm different vendors.
There is no present experience to relate this accelerated exposure to responses of tape in applications where the tape is under a use stress. Astmm example, a given type of tape a speci?
It is superimposed on the variability inherent in performance of the subsequent physical property test for which this conditioning was preparatory. Reagents for Humidity Vessel in Oven procedure 7. Originally approved in This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions asgm in abnormal product. Current edition approved Oct.
This standard has been approved for use by agencies of the Department of Defense. It is not intended for use on electrical grade tapes see Test Methods D These small differences result in slightly different aging of the tape from time to time.
Link to Active This link will always route to the current Active version of the standard. 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 solution within the closed vessel both provides and controls the moisture content humidity within the vessel. A different type of tape could yield data adtm to more or less than that time period. The practice does not provide for a conclusion axtm itself, but is for use in conjunction with appearance or physical property tests to follow the accelerated exposure. While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.

Asmt 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. This may require 24 or 48 h for some materials.
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.

Include no more sample rolls than will displace one fourth of the air volume in the vessel. Include no more sample rolls than will displace one fourth of the air volume in the chamber Unless otherwise indicated, it is intended that all reagents shall conform to the speci?
