Weathering test

Weather resistance refers to the ability of various materials to withstand the test of climate when used outdoors, such as comprehensive damage caused by light, heat and cold, wind and rain, bacteria, etc. Its ability to withstand is called weather resistance. Weather resistance tests require various weather resistance measurement methods to be developed for various materials and different usage conditions, such as various aging tests to simulate natural climate conditions and conduct tests.
For example, the coating weather resistance test, also known as the atmospheric exposure test, evaluates the durability of the coating itself to the atmosphere. The weather resistance of leather can be measured in a weather resistance test chamber (or aging chamber, accelerated weathering tester) that simulates natural climate.
Zhongke Testing Environmental Reliability Experiment Center has various climate environment simulation test equipment and weather resistance test capabilities. It provides professional weather resistance test services for various additives and colorants, adhesives and sealants, automobiles, building materials and other products.

Additives and colorants, adhesives and sealants, automotive, building materials, textiles, food and beverages, graphic arts, paints and coatings, pharmaceuticals and cosmetics, plastics and packaging materials, wind and solar energy and other fields.

Outdoor weather resistance test: direct exposure test, black box exposure test, sun tracking exposure test, sun tracking concentrated light exposure test;
Artificially promoted weather resistance test: sunshine carbon arc lamp weather resistance test, xenon arc lamp weather resistance test.
