(Test Method)Standard Test Method for Effects of Outdoor Weathering on Pipeline Coatings
Standard Test Method for Effects of Outdoor Weathering on Pipeline Coatings
SIGNIFICANCE AND USE
Since coated pipe may be stored outdoors for long periods before burial, weathering tests of the type described in this test method are needed to evaluate the stability of these coatings stored outdoors. The results obtained should be treated only as indicating the general effect of weathering. Exposure conditions vary greatly from year to year, from one part of a year to another, and from locality to locality. The results of short-term exposure tests in the north are more meaningful if exposure is started in the summer followed by a winter season. In southern areas where climatic conditions are more uniform throughout the year, the time of year when short-term exposure is started is less critical. In all localities, the longer the exposure period, the more reliable are the results obtained.
SCOPE
1.1 This test method is intended to define conditions for the exposure of coated pipe to weather.
1.2 This test method specifies qualifications for the samples, procedure to be followed in exposure to weather, and procedure for evaluating effects of exposure including visual examination and other tests.
1.3 The values stated in SI units to three significant decimals are to be regarded as the standard. The values given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

3. Summary of Test Method
3.1 The effects of outdoor weathering on pipeline coatings after 6, 12, and 24 months’ exposure are determined visually and
by electrical means by comparing exposed samples of coated pipe with unexposed samples of coated pipe before and after impact
and bending tests. At the beginning of the test the starting samples are qualified by a cathodic disbonding test.
4. Significance and Use
4.1 Since coated pipe may be stored outdoors for long periods before burial, weathering tests of the type described in this test
method are needed to evaluate the stability of these coatings stored outdoors. The results obtained should be treated only as
indicating the general effect of weathering. Exposure conditions vary greatly from year to year, from one part of a year to another,
and from locality to locality. The results of short-term exposure tests in the north are more meaningful if exposure is started in the
summer followed by a winter season. In southern areas where climatic conditions are more uniform throughout the year, the time
of year when short-term exposure is started is less critical. In all localities, the longer the exposure period, the more reliable are
the results obtained.
