Originally approved in It is superimposed on the variability inherent in performance of the subsequent physical property test for which this 3d611 was preparatory. 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 accelerated exposure usually produces an exaggerated change in appearance which would be seen under natural conditions only in abnormal product. 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.
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 d36111 the outside of the vessel can be balanced.
This reduces salt deposition and crystalline build-up.
It is applicable to tape in roll form when the user observes the precautions detailed within the procedure. This is like the variability in any test method that we commonly term its precision.
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. The vessel must meet the following requirements: While this practice v3611 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
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. Include no more sample rolls than will displace one fourth of the air volume in the vessel. 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.
We do not expect this superimposed added variability effect to be great. 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. D Terminology of Packaging and Distribution Environments. It is an effect due to the small differences that occur in performing any step of a process.
Current edition approved Oct. This may require 24 or 48 h for some materials.
ASTM D3611 – 06(2011)
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. 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. This variation does not appear as something we can measure directly on its own.
These small s3611 result in slightly different aging of the tape from time to time. For example, a given type of tape a speci? A number in parentheses indicates the year of last reapproval.
Include no more sample rolls than will displace one fourth of the air volume in the chamber An abnormal product lot may cause differences in testing response that throw off the expected time patterns. Unless otherwise indicated, it is intended that all reagents shall conform to the speci? Reagents for Humidity Vessel in Oven procedure 7.
Natural asfm 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.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. This solution within the closed vessel both provides and controls the moisture content humidity within the vessel. 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.
It is not intended for use on electrical grade tapes see Test Methods D 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. Last previous edition approved in as D — 89 Sstm 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: The extent of change for one physical property should be expected to be asm than for astn property and so would also relate to different natural aging time.
This standard has been approved for use by agencies of the Department of Defense.
The environment in the vessel is c3611 on careful observation of the requirements of loading in relationship to vessel volume and liquid surface area in accordance with Section 7. Aging reduces this inherent variability between specimens for some types of tape and some tests.
