ISO 105-B02 Colour Fastness of Textiles - Light Fastness Tester

ISO 105-B02 Colour Fastness of Textiles - Light Fastness Tester
ISO 105-B02 is a testing standard published by the International Organisation for Standardisation (ISO) concerning the lightfastness of textiles. This standard specifies a method for evaluating the lightfastness of textiles by simulating exposure to daylight (D65 light source) using a xenon arc lamp apparatus.
Light Fastness Tester

Scope of ISO 105-B02


ISO 105-B02 applies to determining the colourfastness performance of various types and forms of textiles to artificial light sources (simulating natural daylight D65), including white textiles (bleached or fluorescent white).

Requirements for Test Equipment under ISO 105-B02


Light Source: ISO 105-B02 specifies that xenon arc lamp apparatus must possess a stable light source and filter system capable of simulating the spectral distribution of daylight.

Filters and heat filters: Filters are used to stably attenuate the ultraviolet spectrum, while heat filters stably attenuate infrared radiation. Filter transmittance must be at least 90% between 380 nm and 750 nm, dropping to 0% between 310 nm and 320 nm.

Temperature: Depending on test conditions (e.g., temperate conditions commonly used in Europe or American conditions), the black panel temperature varies, typically ranging between 50°C and 63°C.

Irradiance: Radiation intensity is measured using a radiometer, with a recommended value of 42 W/m² (at wavelengths between 300 nm and 400 nm), equivalent to 1.1 W/m² (at 420 nm) in water-cooled xenon lamp equipment.

GESTER Light Fastness Tester GT-D02A-1


This light fastness tester apply to light color fastness, anti-climate color fastness, light & perspiration color fastness and light aging tests of textile, paint, dye, coating, rubber, plastic, wood floor, paper and other materials, it have anti-climate functions of exposing to the rain, revolution and mist spraying


Light Fastness Tester


Feature


  • The 2500W long arc xenon lamp is used to simulate the solar spectrum.


  • Xenon Light Fastness Tester: High transmittance of filter combinations and use 95% of the transmittance filters and filter cartridges. With Low power consumption but achieve the same irradiation light requirements. To make the machine is more energy saving and environment friendly.


  • Standard equipped with 420nm wave band, irradiance digital setting, real time monitoring,  closed loop automatic regulation, providing the most stable irradiance test light source for different standards (340nm, 420nm, 300-400nm and 300-800nm band optional ).


  • With several modes of operation (spray, alternating light and dark, revolution), can simulate the real climate state.


  • Individual timing of each sample clamp may enable different sample test in a same tester and facilitate test monitor and reduce operation cost.

Standards of ISO 105-B02 Light Fastness Tester


GB/T 8427, GB/T 8430, GB/T 14576, GB/T 15102, GB/T 15104, ISO 105-B02/B04,

How is Multi Wire Saw Revolutionising The Production of Granite Slab?

Traditional bridge tower type multi cutting machine has long been pivotal equipment in granite slab production. However, their low efficiency, complex operation, and environmental pollution issues have increasingly rendered them inadequate for modern manufacturing demands. Consequently, multi wire saw for granite slabs have emerged, effectively resolving numerous challenges in contemporary granite slab production.



Specifically engineered for large-scale granite block cutting, the
granite wire saw cutting machine offers multiple specification options and can simultaneously cut granite slabs ranging from 20 to 30 millimetres in thickness. It delivers exceptionally high cutting efficiency while ensuring precision and surface smoothness in the cut slabs. Additionally, its low operational noise significantly improves the working environment.

Key features include:

1.Compact structure with minimal footprint, energy-efficient and environmentally friendly operation, high processing efficiency, cutting speeds up to 0-35m/s, and straightforward operation.

2.Utilises a PLC digital control system, allowing users to customise operational parameters via the display screen for fully automated running.

3.Cooling water used during cutting is recycled, promoting environmental sustainability and resource conservation.

4.Large panel spacers can be automatically positioned during sawing without halting operation, substantially boosting production efficiency.

5.Cut surfaces exhibit superior smoothness while reducing sawing costs.

The multi wire saw machine employs multiple diamond wires to cut granite blocks. These wires, measuring 6.3-7.3mm in diameter, feature a surface coated with threaded diamond beads. Each metre of diamond wire contains 37 beads. These diamond beads act as abrasives, completing the cut under the cooling and cleaning action of a water flow, with excess material discharged with the water flow.

To optimise diamond wire efficiency, the following operational practices are recommended:
Shape the top and bottom surfaces of the block prior to sawing.
The block should be positioned on two supports and secured with cement bonding.
