Unless otherwise indicated, it is intended that all reagents shall conform to the speci? An illustration of this can be made with the peel adhesion test.
Historical Version s – view previous versions of standard. The practice does not provide for a conclusion within itself, but is for use in conjunction with appearance or physical property astmm to follow the accelerated exposure.
ASTM D – 06() – Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes
It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product. Originally approved in This is like the variability in any test method that we commonly term its precision.
Since it is seen as a change in the apparent variability of the physical property test results, we can relate it to sstm expected precision of the test by making the following statement: Therefore this conditioning does not always cause an increase in dispersion.
The 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 accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural aatm only in abnormal product. Appearance of normal tape product will usually aztm only slightly on two years natural aging.
This variation does not appear as something we can measure directly on its own. Current edition approved Oct. This reduces salt deposition and crystalline build-up. 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.
A number in parentheses indicates the year of last reapproval. It is superimposed on the variability inherent in performance of the subsequent physical property test for which this conditioning was preparatory.
An abnormal product lot may cause differences in testing response that throw off the expected time patterns.
ASTM D3611 – 06(2011)
D Terminology of Packaging and Distribution Environments. It is not intended for use on electrical grade tapes see Test Methods D 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. Use separators aetm allow free air space around and between the rolls and which are non-hygroscopic. 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 ast, applicable to tape in roll form when the user observes the precautions detailed astk the procedure. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
A superscript epsilon e indicates an editorial change since the last revision or reapproval.
While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged. 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.
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. These small differences result in slightly different aging of the tape from time to time. 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.
Last previous edition approved in as D — 89 Include no more sample rolls than will displace one fourth of the air volume in the chamber Link to Active This link will always route to the current Active version of the standard. 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.
ASTM D – 89() Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes
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. It is an effect due to the small differences that occur in performing any step e3611 a process.
We do not expect s3611 superimposed added variability effect to be great. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
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. Reagents for Humidity Vessel in Oven procedure 7. 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.
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. This solution within the closed vessel both provides and controls the moisture content humidity within the vessel. Include no more sample rolls than will displace one fourth of the air volume in the vessel. 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. While this practice was developed using packaging type tapes, its use on other qstm of tape with similar construction is encouraged. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The extent of change for one physical property should be expected to be different than for another property and so would also relate asttm different natural aging time.
