Understanding Color Fastness to Ozone What is an Ozone Test in Garments? Color fastness to Ozone (ozone test chamber) is intended for assessing the Ozone resistance of color of textiles of all kinds and in all forms when exposed to atmosphere with certain temperature and humidity. Assessing Ozone Resistance. How Do you Test for Ozone Resistance? 1. Add purified water at the water filling point of the ozone test chamber. 2. The water level should be increased to about 60-70. Turn on the power air switch at the back of the machine. 3. Press [Power] button at the panel to turn on the power. [Lighting] is the button to turn on the light in the test chamber. 4. Click [Fix Test] to enter fix test page. 5. Set the test temperature and humidity according to the standard. 6. Click [Start] to run the test. After the displayed temperature and humidity reach the set value and become stable. 7. Start to set the concentration value of the ozone meter. 8.Click [《PF] and up & down arrow to set the ozone concentration value. Warm tips: Please set the ozone concentration according to standard. Place the sample on the sample holder in the test chamber. 9. Click [Ozone] to turn on the ozone, ozone value starts to increase. When the test time specified in the standard is reached, it means the test is completed. Press the [Ozone] ozone switch to turn off ozone and press [CLEAR] the ozone clearing switch. 10. When the ozone in the test chamber is cleared, the light of the [CLEAR] button will go out. 11. When the [CLEAR] button is dark, it shows that the current ozone value in the test chamber is low, and the sample can be taken out. How to Improve Color Fastness to Ozone? The ozone colourfastness testing system places the sample in an ozone environment of a certain concentration until a certain colour change occurs or a specified time has elapsed, after which it is compared with a standard colour chart. Although ozone is present in very low concentrations in the atmosphere, it can significantly affect the colour of textile dyes. The Ozone Resistance Test Chamber simulates and intensifies atmospheric ozone conditions to study the mechanisms by which ozone affects fabric colourfastness. It provides a rapid method for evaluating fabric resistance to ozone-induced colour fading and assessing the efficacy of ozone-resistant agents, enabling the implementation of appropriate measures to prevent colour fading and thereby extend the service life of textiles.

GESTER Machines For EN388 2016: Protective Gloves Against Mechanical Risks EN 388: 2016 Overview EN 388 is one of the most common European standards for testing protective gloves against mechanical risks in general industry applications. EN 388 includes four performance tests: abrasion resistance, blade cut resistance, tear resistance, and puncture resistance. The performance of the glove is graded in accordance with four or five performance levels. The end user is then able to select a glove with a performance level profile that suits a particular work activity. So for example, a glove could be performance level 4 for abrasion but level 1 for tearing (in European standards the higher the number, the greater the protection). Testing for EN 388: 2016 Sampling and conditioning GESTER Equipment: GT-C52 Programmable Temperature & Humidity Test Chamber Capacity: 80L or 150L (pls choose one) Humidity range: 20%~98% Temperature range: -20~150°C Power Supply: 1∮ AC 220V 50/60HZ Standard Accessories: Operation Video, Certificate of quality, English operation manual. Abrasion Samples are cut from the palm of a glove and rubbed against an abrasive paper using a “Martindale” type abrasion machine. The number of cycles for the samples to hole is measured. The level of protection is expressed in grades 1 to 4 and depends on the number of revolutions required before a hole appears in the material. The higher the number, the better the abrasion resistance. GT-KC13B Martindale Abrasion Tester Conforms to EN388 standard. Testing position: 4 Control mode: PLC control and touchscreen display Standard Accessories: Abrasion Weight and Holder (1Set), Pilling Weight and Holder (1 Set), Standard Abradents Fabric (2 pcs/head), Standard Backing Foam 38mm (60pcs), Standard Woven Felt Discs 140mm (2 pcs/head), Standard Woven Felt Discs 90mm (2 pcs/head), Photographs (Copy one), Sample cutting template (D 38/90/140mm, each 1pc), Pressing Weight (1pc), Bowl shape sample loader (1pc), Steel ball (3pcs), Power line (1pc), English manual, Certificate of quality. Blade Cut Samples are taken from the palm of a glove and the number of cycles to cut through the full thickness of the test sample by a circular rotating blade is recorded. Blade sharpness will vary and is assessed by using the cut test machine to cut through a standard reference fabric. The cut resistance of the glove is based on a relative index that compares the number of cycles to cut through the glove when compared with the standard fabric. Five performance levels are defined in EN 388 ranging from level 1 = Cut index > 1.2 to Level 5 = Cut index > 20. GT-KC29 Safety Glove & Shoe Upper Cutting Tester Stroke: 50 mm Load: 50±0.5 N Specimen holder: 2 sets Circular blade: Diameter 45±0.5mm, Thickness 0.3mm, Cutting angle 30°~35° Max.
