About Light Fastness Tester

For most materials, colourfastness against artificial light is an important property that determines their suitability for many specific end uses. This characteristic is determined by exposing test specimens taken from the sample under test to a controlled intensity of artificial light under a specified humidity and temperature to obtain a specified degree of exposure. The actual degree of exposure is assessed with the help of colourfastness rating standards (blue standards), which are exposed along with the test specimens. Colourfastness rating is determined with the help of grey scale for change in colour.

The GLOBE Light Fastness Tester consists of a mercury vapour lamp, which is mounted in the centre of a cylindrical drum on which the test specimens are mounted. The drum is rotated at a constant speed to obtain an even exposure all over its inner surface. Humidity is maintained with the help of a standard saturated salt solution, which is kept in a stainless steel tray located below the drum. A fan is provided for gently stirring the air.

Advanced Testing Capabilities

This Light Fastness Tester features a high-powered Xenon Arc or Tungsten Lamp to closely replicate the effects of sunlight, ensuring reliable testing of textile samples. With a customizable temperature range, adjustable humidity, and standard specimen sizes, users can match real-world conditions to laboratory precision. Its programmable timer offers flexibility for various testing durations.

User-Friendly Operations

The device boasts a digital control panel with status indicators, a calibrator, and a large viewing window for easy monitoring. The design incorporates stainless steel sample holders, air-cooling fans, and a sturdy chamber made from mild steel, supporting rigorous and consistent testing routines.

Comprehensive Accessories Provided

Included accessories such as 8 Blue Wool Standards, humidity cards, sample templates, and adjustable sample holders streamline both setup and measurement. The testers electrical compatibility and robust construction make it an excellent choice for institutions and manufacturers focused on product longevity and quality assurance.

FAQs of Light Fastness Tester:

Q: How does the Light Fastness Tester simulate sunlight for testing purposes?

A: The tester uses a 500 Watt Xenon Arc or Tungsten Lamp to mimic the spectral energy distribution of natural sunlight, replicating real-world conditions for evaluating the color fastness of textiles.

Q: What types of materials can be tested with this equipment?

A: This instrument is designed for fabrics, yarns, and dyed materials, making it suitable for the textile industry, research laboratories, and quality assurance departments.

Q: When should the lamp be replaced in the Light Fastness Tester?

A: The lamp should be replaced after approximately 500 hours of operation. The programmable digital timer helps monitor usage to determine when replacement is necessary.

Q: Where is the best place to install the Light Fastness Tester for optimum performance?

A: Install the tester in a well-ventilated, clean laboratory or testing area, ensuring access to a 220V AC / 50 Hz power supply and a stable, level surface to accommodate its dimensions and weight.

Q: What is the process for testing textile samples in the chamber?

A: Samples are clipped using stainless steel adjustable holders, placed within the chamber, and subjected to the programmed light, temperature, and humidity conditions. The process duration is set via the digital timer, and test standards like Blue Wool are used as references.

Q: How many specimens can be tested simultaneously in the chamber?

A: The tester can accommodate up to 24 specimens at once, each mounted using adjustable stainless steel clips for even exposure to the light source.

Q: What benefits does this Light Fastness Tester provide to textile manufacturers and researchers?

A: It enables accurate, reproducible testing of color fastness, providing confidence in textile durability and quality assurance. This leads to better product reliability before market release, minimizing returns and enhancing customer satisfaction.
