The type and rate of degradation and the performance rankings produced in exposures to fluorescent UV lamps can be much different from those produced by exposures to other types of laboratory light sources. Do not place the apparatus near a heat source such as an oven. Rubber Testing Machine All references to exposures in accordance with this practice must include a complete description of the test cycle used. Up to 20 test samples are mounted in the QUV and subjected to a cycle of exposure to intense ultraviolet radiation followed by moisture exposure by condensation.

This practice is intended to induce property changes associated with end-use conditions, including the effects of sunlight, moisture, and heat. Historical Version s - view previous versions of standard.
Turn the device d44587 before removing panels for inspection.
When a single exposure period is used, select a time or radiant exposure that will produce the largest performance differences between the test materials or between the test material and the control material. Note 1—Previous versions of this practice referenced fluorescent UV devices described by Practicewhich described very specific equipment designs. The heating mode adopts inner bladder trough type heating with its rapid temperature rise and even temperature distribution.
B The irradiance set point given is typical for devices operated without irradiance control. Auditing Consulting Sourcing Training. Precision and Bias We can offer operation video and English operation muanual.

The measurement data used to establish these set points was inaccurate, due to an error in calibration on the part of one manufacturer.
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.
SUS steel Temperature control: Do not use this covered area of the specimen as part of the test area.
B The irradiance set point given is typical for devices operated without irradiance control. Provide reference with testing data for improvement of existing materials, or to assess the impact of changes in product durability and other aspects.
