July 2020, our flame retardant fabric Fiji has been successfully tested EN 1149-5:2018 (Protective clothing. Electrostatic properties) after 50 Industrial Washes!
EN 1149-5 is European standard for garments that protect against electrostatic discharge where there is a risk of explosion e.g. in oil refineries.
It is part of a series of standards for test methods and requirements for electrostatic properties of protective clothing.
EN 1143-3 is a test method, that uses induction charging to evaluate how fast a fabric discharge, i.e. looses its electrostatic charge via air. According to the Standard the charge decay value should be no more than 4 seconds according to test method EN 1149-3. It means that antistatic fabric should loose its electrostatic charge in less than 4s.
The testing was done at independent international laboratory AITEX (Spain).
Fiji is a light flame retardant fabric with classic twill weave, developed specially for light flame retardant clothing. Fiji protective fabric is recommended for use as a middle layer of FR-clothing, like shirts, vests, light pants, or even light overalls for hot climate.
Fiji has been successfully tested to the following test:
CHARGE DECAY (EN 1149-3:2004 – after 50 washing cycles at 400C, ISO 6330:2012, Tumble Dry, F) – performance level – PASS
According to Standard EN 1149-5:2008 for the induction charge method (EN 1149-3:2004) the requirements are:
t50< 4 s or S > 0,2
During the testing, Fiji has demonstrated the following results:
- S = 0,21 – Shielding factor – PASS
- t50 = < 0,03 – Decay half time – PASS
It means that when tested, Fiji fabric dissipated (lost) its electrostatic charge in less than 0,01 second. So it’s 400 times better, than EN 1149-5 requirements.
