August 2019 our cotton flame retardant fabric Volcano has been successfully retested and renewed EN 1149-5 (Protective clothing. Electrostatic properties) certificate.
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).
Super multi-functional Flame Retardant fabric with Antistatic properties. Volcano is made of 87% cotton/ 12% nylon, 1% Antistatic, weight 260gsm and best used for protective clothing. Certified by EN ISO 11611, 11612, EN 1149, EN 13034. It is an excellent choice for FR-clothing of oil and gas companies, operating in a warm or hot climate. Due to elegant and smooth satin weave, protective clothing made of Volcano fabric looks impeccable on rig chiefs of offshore platforms as well as on manager staff in the office of petroleum company.
Volcano has been successfully tested to the following test:
CHARGE DECAY (EN 1149-3:2004 – after 5 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, Volcano has demonstrated the following results:
- S = 0,69 – Shielding factor – PASS
- t50 = < 0,01 – Decay half time – PASS
It means that when tested, Volcano fabric dissipated (lost) its electrostatic charge in less than 0,01 second. So it’s 400 times better, than EN 1149-5 requirements.
