Model parameter table of yellowing resistance test chamber SPECIFICATION

Applicable Standards:

The testing of yellowing and aging resistance of exterior wall coatings generally follows recognized industry standards:

1. ISO 4892-3: This international standard outlines the method for accelerated weathering testing of plastics and coatings, which includes UV exposure, and is used to evaluate the aging and yellowing resistance of exterior coatings.

2. ASTM G154: This standard from the American Society for Testing and Materials specifies procedures for accelerated exposure to UV light and is often used to evaluate coatings, paints, and other materials.

3. GB/T 16422.1: This Chinese national standard provides a methodology for accelerated weathering testing on coatings and materials exposed to UV light, ensuring that coatings can withstand outdoor conditions.

4. EN 927-6: This European standard applies to the weathering testing of exterior wood coatings and is used to assess the durability and yellowing resistance of such coatings, though it may also be relevant for other coatings on exterior surfaces.

Wire and cable yellowing resistance aging tester is a special equipment for evaluating the yellowing resistance and aging characteristics of wire and cable and other materials. The following is a detailed description of the equipment:

1. Equipment function

Wire and cable yellowing aging tester is mainly used to simulate the natural aging environment, through high temperature, light, humidity and other conditions to accelerate the aging process of the material, so as to quickly assess its yellowing resistance, tensile strength, elongation and other aging characteristics. For example, through a day's test at 70℃, it can theoretically simulate the effect of materials exposed to the atmosphere for 6 months.

2. Application Scenarios

The equipment is widely used in the wire, cable, insulator, rubber, plastic, artificial leather and other industries to test the changes in the properties of materials during the aging process in order to assess their service life and reliability.

3. Working Principle

- Hot air circulation: the equipment heats the sample evenly by hot air circulation to ensure uniform temperature distribution.

- Air exchange device: Some of the equipments are equipped with air exchange device, which can keep the air inside the box fresh and avoid the influence of pollution on the test results.

- Temperature control: The equipment adopts digital display instrumentation for precise temperature control to meet the needs of different testing standards.

- Over-temperature protection: the equipment is usually equipped with over-temperature automatic cut-off protection device to ensure the safety of the testing process.

4. Main Technical Parameters

- Temperature range: usually from room temperature to 150℃ or higher.

- Humidity control: Some devices support humidity adjustment to simulate high humidity environment.

- Light intensity: Light intensity and wavelength distribution can be adjusted according to test requirements.

- Testing time: Different testing cycles can be set, such as 1 day, 3 days, 7 days, etc., to simulate different aging degrees.

5. Equipment Advantages

- High efficiency: Compared with the natural aging test, the equipment can significantly shorten the test time and reduce the cost.

- High accuracy: Reliable test results are obtained through precise control of environmental parameters (e.g. temperature, humidity, light).

- Strong applicability: can test a variety of materials, such as rubber, plastic, wire and cable.

- High safety: the equipment is equipped with multiple protection devices, such as over-temperature protection, to ensure the safety of the testing process.

6. Relevant test standards

The equipment complies with a variety of international and industry standards, such as:

- JIS-P8127 (Japanese Industrial Standard)

- ASTM D1148 (American Society for Testing and Materials)

- UL-1581 (Underwriters Laboratories Safety Standard).

Through the above introduction, the wire and cable yellowing resistance aging tester is an efficient and accurate testing tool, widely used in the field of material aging performance evaluation.
