Foreword
This standard also replace the GB/T 2573-1989 "glass fiber reinforced plastics atmospheric exposure test method", GB/T 2574-1989
"Plastic glass fiber reinforced heat test method", GB/T 2575-1989 "Test method for plastic water resistance of glass fiber reinforced" and
GB/T 10703-1989 "glass fiber reinforced plastic water resistance accelerated test methods."
This standard and GB/T 2573 ~ 2575-1989 and GB/T 10703-1989 compared to the main changes are as follows.
--- The GB/T 2573 ~ 2575-1989 and GB/T 10703-1989 merged into one standard;
--- Reduce some references (GB/T 2574-1989, GB/T 2575-1989 and GB/T 10703 - 1989 Edition Chapter 2,
Excerpts of chapter 2);
--- Increase natural weathering definition (see Chapter 3);
--- Increase test principle (see 4.1.1,4.2.1,4.3.1 and 4.4.1);
Schematic diagram of the test equipment (GB/T 2573-1989 of 5.1) --- deleting atmospheric exposure;
--- Increased solar radiation measuring equipment (see 4.1.2.2 and 4.1.2.3);
--- Modify the direction of atmospheric exposure requirements, and exposure to a predetermined angle by latitude and 45 ° angle depending on the purpose of selecting different exposure
Exposure angle (GB/T 5.4 in 2573-1989, this standard 4.1.4.1);
--- Modify atmospheric exposure site requirements, increased climatic conditions (GB/T 2573-1989 in Chapter 4, this standard 4.1.4.2
And Appendix A);
--- Increase in atmospheric exposure stage requirements (GB/T 2573-1989 of 6.4, this standard 4.1.4.3);
--- Increased atmospheric exposure test record requirements meteorological conditions (see 4.1.5.5).
The Standard Appendix A and Appendix B are informative.

2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB/T 1446 Test methods for fiber reinforced plastic properties General
Plastic bending performance test method GB/T 1449 fiber reinforced
3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
It means that the material is installed at a fixed angle or angle change with the seasons experiment rack, long-term exposure to the natural environment. Such exposure is generally
Used to assess the impact of environmental factors on the various properties of the material.
3.2
Glass fiber reinforced plastics after immersion in water, wet bending strength gradually decreased with time, when the rate of change approaches zero as the bending strength
Wet bending limit strength.
Test Method 4
4.1 Atmospheric exposure test
4.1.1 Test principle
Exposed parts exposed to natural sunlight, the provision of post-exposure phase, removed from the exposed shelf, measured their appearance, physical or mechanical properties
Changes to natural climate evaluation materials aging properties.
4.1.2 Test Equipment
4.1.2.1 experiment rack
Experimental frame by the frame, support frame and the other clamping device component. Experimental aircraft should be suitable for the type of exposure member can be mounted on a flat frame
The holder, the holder fixed to the frame, the angle of inclination and azimuth holding means test should be adjusted.
Framework experiment frame, support frame and the other clamping device application does not affect the test results of an inert material, it is appropriate corrosion-resistant aluminum alloy
Gold, stainless steel or ceramic, it can also be used by the anti-corrosive (such as copper - chromium - arsenic mixture) suitable impregnated wood or those that have proven not affect exposure
The test timber. Direct exposure member mounted on the frame or support frame mounted on the first and then fixed to the frame, the frame should be able to experiment rack mounted to the
Predetermined angle of inclination, and any portion of the exposed parts of the ground or any other obstacles from the distance should not be less than 0.5m. Holding means
Should be firm, try to keep the sample in a small stress state to ensure the exposed parts free shrinkage, warpage and expansion.
