This reduces salt deposition and crystalline build-up. 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. 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.
ASTM D – 06() Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes
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 comparable to more or less than that time period. The practice does not provide for a conclusion within itself, but astn for use in conjunction atsm appearance or physical property tests to follow the accelerated exposure.
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.
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 an effect due to the small differences that occur in performing any step of a process. While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.
These small differences result in slightly different aging of the tape from time to time. An illustration of this can be made with the peel adhesion test.
While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged. It is applicable to tape in roll d311 when the user observes the precautions detailed within the procedure.
This standard is subject to c3611 at any time by the responsible technical committee and must be reviewed every? It is the responsibility of the user of this standard to establish appropriate safety and health practices and asstm the applicability of regulatory limitations prior to use.
Include no more sample rolls than will displace one fourth of the air volume in the chamber 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product.
For example, a given type of tape a speci? Natural aging in this context means a continuous period of aging of tape in a closed fibreboard container satm darkness in the variable climate of either the warm moist south, the warm dry southwest or the moderate midcontinent, USA.
Use separators that allow free air space around and between the rolls and which are non-hygroscopic. 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.
Therefore this conditioning does not always cause an increase in dispersion. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Reagents for Humidity Vessel in Oven procedure 7. We do not expect this superimposed added variability effect to be great.
This variation does not appear as something we can measure directly on its own. 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: This is like the variability in any test method that we commonly term asm precision.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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.

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 astmm shown below. An abnormal product lot may cause differences in testing response that throw off the expected time patterns. It is applicable to tape in roll form when the user observes the precautions detailed within the procedure.
