Description

Features of Light&Weather Fastness Tester TF420

Digital setting of light intensity, real-time monitoring, closed-loop control, and automatic adjustment so that it can meet different standards. (Standard 420nm; 340nm, 300~400nm, 300~800nm available on request).

Simulation of real sunlight and climate state: using a 2500W long-arc xenon lamp, a real simulation of daylight spectrum, and a variety of operating modes (rain, alternating light and dark, public rotation, self-rotation), to create a real climate state.

Accurate and stable test temperature and humidity: industrial temperature control (cooling) system, multi-stage ultrasonic humidification intelligent control system, rapid adjustment of the test chamber temperature and humidity to ensure accurate and stable test temperature and humidity.

More accurate reflection of sample test results: black panel thermometer (BPT), standard black panel thermometer (BST), radiometer, and sample at the same station (equidistant) detection, the measured data using wireless radio frequency technology synchronous transmission.

Efficient mode reduces operating costs: all specimen clamps achieve separate timing, can be carried out at the same time with different samples of the experiment, are convenient for test monitoring, and practical, and greatly reduce costs.

Color touch screen display, a variety of expressions: digital, graphs, etc.; can display light irradiance, temperature, and humidity curve in real-time.

Application of Light&Weather Fastness Tester TF420

It is used for testing the color and performance changes of various textiles, leather, artificial leather, garment, automobile interior parts, plastics, dyes, coatings, paints, and other colored materials, by adjusting the temperature, humidity, rain, and other test conditions in the test chamber, as well as using xenon lamp and light filtering system to reliably simulate the full spectrum of daylight, test the material light fastness, sunlight weather-fastness and light aging resistance.

TESTEX Light & Weather Fastness Testing Machine TF420 has multi-point adjustment functions. They are mainly online control of the light intensity, automatic detection, and compensation of light energy, closed-loop control of temperature and humidity, and the control of blackboard temperature circuit. Based on these applications, you can call this weather meter a light fastness tester or fadeometer. In addition, it can shorten the testing time by using xenon arc irradiation in a chamber, thus we can also call it a xenon arc weather o meter chamber.

For the testing of textiles’ color fastness, you can also choose a Water-cooled Light & Weather Fastness Tester as an alternative.

The Test Principle of the Light &Weather Fastness Test

The equipment uses a full-spectrum xenon arc lamp light source, through a special filter glass, in the test chamber to produce a specific glass window sunlight spectrum, exposure to the specimen, as well as a combination of temperature, humidity, rain, condensation, and other natural environment simulation, comprehensive action on the specimen. When the test is completed, the light fastness and aging of the test material are evaluated mainly by observing the fading, discoloration, brittleness, cracking, cracking, color peeling, and other phenomena of the material. The fading and aging grade of the product is usually evaluated with a gray sample card and blue wool standard (blue standard).

What is Light Fastness &Weather Fastness?

Light fastness is also called “sunlight fastness”. It refers to the ability of the product to maintain its original color after being exposed to sunlight. From poor to good, divided into 1 ~ 8 levels. Weather fastness or aging resistance is the durability or product life of goods such as plastic, rubber, architectural coatings, and fiber materials exposed to sunlight, heat and cold, wind and rain, and other climatic conditions. When the light &weather fastness test is running, adjust the temperature of the test chamber, humidity, rain, and other test conditions, with the xenon lamp simulating the effect of sunlight, to test the material’s light fastness and aging resistance.

The test principle


In the test, put the textile specimen and the mutually agreed reference standard specimen (blue standard wool) under exposure to sunlight according to the specified requirement. Then compare the degree of their discoloration. At the same time, we can make a determination of the grade of light fastness of the textile specimen, which is based on the blue wool light fastness standard sample exposed to sunlight. Besides, all the test standards of sunlight fastness apply a relative comparison method. However, the exposure equipment does not directly show the test results. The performance of the equipment mainly depends on the control of the parameters which affect the test environment, including the spectrum, light intensity, temperature, relative humidity, etc.



Test procedures


Humidity regulation

1 Check whether the equipment is in good operating condition


2 Put a humidity control specimen on a hard card together with a blue wool standard and place it in the middle of the specimen holder as far as possible.


3 Place the loaded specimen holder on the specimen holder of the equipment


4 After turning on the xenon lamp, keep the equipment running continuously until the test is completed.


5 put the partially covered humidity control specimens and blue wool standard at the same time under exposure to the sunlight.


Methods of exposure to sunlight

Under predetermined conditions, the specimen and the blue wool standard should be exposed to sunlight at the same time.


Method 1

This method is considered to be the most accurate and should be used when ratings are in dispute. Its basic feature is to control the exposure period by checking the specimen

1 Place the specimen, the blue wool standard, and the cover in accordance with certain requirements, and expose them to the xenon lamp, lifting the cover from time to time to check the light effect of the specimen.


2  Expose the specimen to the sunlight in accordance with the required degree.

Method 2

1 This method is suitable for testing a large number of specimens at the same time. The basic feature is that the exposure period is controlled by checking the blue wool standard, and only one set of the blue wool standard is used to test a batch of specimens with different light fastness, thus saving the material used for the blue wool standard.


2 The specimens and blue wool standards are covered and then exposed until the relevant requirements are met.



Troubleshooting


1 If the power is turned on and there is no display, it means that the power is not on or the power indicator is damaged. If the power indicator is damaged, replace it. If there is no power output on the power output terminal, please check the power cord or energized socket.


2 If the power is turned on and there is an indication on the power indicator, but the machine does not work when pressing the start button, please check whether the relay has dropped or disconnected. If so, please promptly connected. But if there is no drop or disconnection, indicating that the relay has been damaged, then replace it in time.



Dos & Don’ts when operating the xenon lamp weatherometer?


1 Do not open the right box cover during the operation of the equipment. The right box body of the weather ometer is mainly the electrical function component. There is a high dangerous voltage above 10kV when the xenon arc lamp flip-flop works. Removing the lid of the box may cause the personnel to touch the electrical component part, resulting in an electric shock.


2. Do not try to manually press the protection switch of the test storehouse for lighting operation when the test storehouse glass door is opened. It is forbidden to open the test storehouse glass door when the xenon arc lamp is ignited.


3. Do not directly view the xenon arc lamp light source of the fadeometer in the unprotected state to avoid damage to the eye.


4. Operators should keep their attention in the process of operation in order to prevent the occurrence of dangerous failures caused by negligence.


5. The xenon arc weatherometer must be disconnected from the power supply before the maintenance of the equipment. The maintenance of the light fastness testing machine, especially for the electrical part, should be operated by special technicians.
