<br />Test Methods E96/E96\I), or Test Method F1249, Conform to
<br />permeance requirements in Table 1.
<br />7.4.3 Permeance after Exposure to Ultraviolet Light—Refer
<br />to Test Methods E154, Section 15. Conform to permeance
<br />requirements in Table 1.
<br />8. Sampling
<br />R.f
<br />Fn r Pnrh Comtnlete set of tests, Obtain all camp les from
<br />a single production roll of material. Samples shall be represen-
<br />tative of the material being sold to the end user.
<br />9. Certification
<br />9.1 When specified in the purchase order or contract, the
<br />purchaser shall be furnished with certification that samples
<br />representing each lot have been either tested or inspected as
<br />directed in this specification and that requirements have been
<br />met.
<br />9.2 Upon the request of the purchaser in the contract or
<br />order, the certification of an independent third party (testing
<br />laboratory) indicating conformance to the requirements of this
<br />specification may be considered.
<br />9.3 When specified in the purchase order or contract, the
<br />producer or supplier shall furnish a summary of the test
<br />procedures listed in Table 1, providing for each test the
<br />laboratory that performed or witnessed the test, the date of the
<br />most recent test, and the test results.
