GB/T 22411-2008Test method of antiaging for plastic woven packaging of dangerous goods (English PDF)

3.1

By the low-pressure mercury arc 254nm radiation produced by the fluorescent substance is converted into longer-wavelength ultraviolet light, the light emitting

Below 400nm UV light energy of at least 80% of the total light energy output, the spectral energy distribution of the emission spectrum of the fluorescent substance and glass

UV transmission performance pipe decision.

3.2

Below 300nm light greater than 10% of the total energy output of a fluorescent lamp UV emission wavelength peak at 313nm.

3.3

After a predetermined surface of the sample into the night-time illumination without illumination state where the surface of the sample still being exposed to hot air and indoor

The mixture was heated with saturated steam action, continues to be a sample while the back air space around the cooling, condensation of the sample surface exposed is formed status.

3.4

Polyolefin plastic flat yarn woven packaging.

Principle 4 4.1 dangerous goods plastic woven using regular long-term exposure to outdoor sunlight, however, usually requires the use of specific laboratory source

Accelerated aging test to more quickly determine the effect of sunlight, humidity on the mechanical properties of plastic woven packaging of dangerous goods. From the sample

The force parts (such as. fabric, harnesses, slings, sutures, etc.) test specimens exposed to fluorescent UV lamp simulate sunlight, humidity cause

Aging. After the exposure test the mechanical properties, and test results and at the same time exposed samples were not taken after the test results […]
