This accelerated exposure usually produces an exaggerated astk in appearance which would be seen under natural conditions only in abnormal product. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Summary of Practice 4. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Unless otherwise indicated, it is intended that all reagents shall conform to the speci?
This is like the variability in any test method that we commonly term its precision. Link to Active D6311 link will always route to the current Active version of the standard.
ASTM D3611 – 06(2011)
It is superimposed on the variability inherent in performance of the subsequent physical property test for which this conditioning was preparatory. A superscript epsilon e indicates an editorial change since the last revision or ast. While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.
If you feel that your comments have not received a fair hearing you d36111 make your views known to the ASTM Committee on Standards, at the address shown below. 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. Historical Version s – view previous versions of standard.
This may require 24 or 48 h for some materials. An illustration of this can be made with the peel adhesion test. A different type of tape could yield data comparable to more or less than that time period.
Therefore this conditioning does not always cause an increase in dispersion. Originally approved in It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. NOTE f3611 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.
While this practice was developed using packaging type tapes, its use on other types of tape with similar construction is encouraged.
ASTM D – 06() Standard Practice for Accelerated Aging of Pressure-Sensitive Tapes
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. 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.
Immediately atm the sample rolls from the assembly. It is an effect due to the small differences that occur in performing any step of a process.
An abnormal product lot may cause differences in testing response that throw off the expected time patterns. 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.
Since xstm 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: We do not expect this superimposed added variability d611 to be great.
Last previous edition approved in as D — astj For instance, when repeating this conditioning one might not set the temperature exactly the same or the atmospheric pressure might vary or the purity asgm the salt might differ from different vendors.
This standard has been approved for use by agencies of the Department of Defense. 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.
Use separators that allow free air space around and between the rolls and which are non-hygroscopic. 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 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. This variation does not appear as something we can measure directly on its own. Reagents for Humidity Vessel in Oven procedure 7. This solution within the closed vessel both provides and controls the moisture content humidity within the vessel.
