A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.
The assessment may be within a roll of tape, between rolls or production lots. Current edition approved April 1, Originally approved in The values stated in each system are not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems d36544 result in non-conformance with 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.
Summary of Test Method 3.
The panel is mounted vertically, a standard mass is attached to the free end of the tape and the time to failure is determined. The panel is mounted vertically, a standard mass is attached to the free end of the tape and the time to failure determined.
The panel is mounted horizontally, tape side up, with the free end of the tape allowed to hang vertically over the rounded end.

The panel is mounted horizontally, tape side up, with the free end of the tape allowed to hang vertically over the round end of the panel.
A standard mass is attached to the free end of the tape and allowed to act for a speci? A specimen size of 24 by 24 mm [1 by 1 in. This qstm or may not relate to the ability of the tape to adhere to other surfaces. This may be used to compare the shear adhesion of a tape to a particular?
Take care in the choice of samples wstm when comparing results between? The c3654 of an elevated temperature during test asm to reduce the duration of the test. Two cutters, 12 mm [0.
NOTE 1—The mm [0. The edges for about mm [5 in. The width of the bar for 75 mm [3 in. The razor shall be held in position using side plates. The edges shall be separated by 12 6 0. The 24 mm [1 in. If it is desirable to test slightly different widths for example, 25 of 50 mm of specimens per 8. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. Other grades may be used, provided it is? The surface roughness height shall be 50 6 25 nm [2.
Panels showing stains, discolorations, or numerous scratches are not acceptable. New panels should be cleaned before use as described in Between uses, the panels test surface shall be protected from scratches and contamination, and the panels stored at conditions described in 8.
The radius of the curvature of the? The surface shall be a true cylinder void of any convex or concave deviations. The mass of the roller shall be 6 45 g [4.
The roller shall move either mechanically or by hand at the rate of 10 6 0. The mass of the clamp or hook described in 5. The mass of the clamp or hook as described in 5. To be suitable, materials must be lint free during use, absorbent, contain no additives that are soluble in the solvents listed in 6.
For Procedures A, E, and H three replicate specimens shall be averaged in accordance with Section 11 for each test result. No single value shall be considered as representative of the roll under test.

Practice E is recommended. It is xstm to test at least? Test specimens should be taken from several rolls of a tape and, whenever possible, among several production runs of a tape. Strong conclusions about a speci? For procedures B, C, D, and G remove?
Where width or other factors causing high adherence to backing make it impossible to remove the specimen at the prescribed rate, remove it at a rate as close to mm [30 in. NOTE 3—Take care that the?
Record the time elaspe in which the tape specimen has separated completely from the test panel see Fig. The tape must be at a true right angle to the bent Repeat for a total of three washes with this solvent. Do not touch cleaned panel surfaces with? Warning— All operations with solvents should be conducted in a wellventilated hood.
NOTE 4—Discard panels showing stains, discoloration, or many scratches. During storage, panels should be protected from d654 or contamination.
It may be desirable to mask the exposed adhesive of the free end of the specimen. Roll down the test area twice in each lengthwise direction with the rubber-covered steel roller described in 5. For Procedures A and H, substitute steel panel instead of?
Allow the remaining mm [8 in. Measure any slippage that has occurred to the nearest 1 mm [1? Record the time elapse in which the tape specimen has completely separated from the test panel. D36654 the arithmetic mean of all logarithms and then convert back to time by obtaining the appropriate antilogarithm.
This gives the test results for the roll of tape under consideration in the sampling plan. Conduct an analysis of the logarithm of the data to determine the d354 descriptive or comparative statistics. The resulting means and con? Use of the Weibull distribution is an acceptable alternative. Some computer programs for data analysis allow the use of right-censored data.
These censored data may have a satm to termination rather than a time to failure. For Procedures E, F, and G the amount of slippage in mm [in.
Width of specimen for Procedures E, F, and G if other than 12 mm [0. Good cohesion r3654 necessary for clean 3d654. Adhesion is a bond produced between a pressure-sensitive tape adhesive and a surface for Procedures A, B, C, D, and H; and, Precision and Bias Examples of averages and with-in-roll standard deviations including test error are as follows: For Procedures F and G, substitute a?
The results are available. The tapes tested in this study had a grand mean of 1. The components of the variance for the following factors were estimated: Between laboratories Between testers Between rolls Residual 0. One company reports that, with care, the asstm laboratory standard deviation and the residual including within roll standard deviation may be higher or lower than reported here, depending on the tape type and manufacturer.
