What aging tests do resin adhesives do?

There are two kinds of aging tests for resin adhesives, one is the damp heat cycle test, and the other is the xenon lamp artificial climate test
.

First, the damp heat cycle aging test: The damp heat cycle aging test is to place the specimen in a handmade environment to control the humidity at 95% RH, and raise the temperature from room temperature 25 °C to 50 °C within one hour to obtain the moisture and heat resistance
of the material under long-term high temperature and high humidity conditions.

The test data after a certain period of time is used as the result of
the aging test.

Reference standard: GB/T50367-2013 "Design Code for Reinforcement of Concrete Structures" "Adhesive (resin) for reinforcement of reinforced concrete load-bearing structures, the steel-steel bonding shear resistance can be tested
by damp heat aging inspection.
"
The damp heat aging test should be tested under the ambient conditions of 50C temperature and 98% RH relative humidity, and the important components should not be less than 90d; For general components shall not be less than 60d
.

Xenon lamp artificial climate test: Xenon lamp artificial climate test is the use of xenon light source, continuous illumination, control a certain temperature (63±3 °C), humidity (65±5), radiation energy (300 ~ 890nm), rainfall cycle and time (18min)), simulate and strengthen the natural climate conditions in the light, heat, oxygen, moisture, rainfall and other major environmental factors, to accelerate the aging of the sample, and the sample in a certain time of detection data as the result of the aging test
。
Reference standard: GB/T14522-1993 "Artificial climate acceleration test method for plastics, coatings and rubber materials for mechanical industrial products" in the artificial climate test
of xenon lamp.
