February 2019, our cotton polyester flame retardant fabric Poseidon-300 has been successfully retested and renewed EN 1149-5:2018 (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).
Poseidon 300 is a high quality poly-cotton fabric with high content of cotton, improved by addition of polyester and antistatic yarn. It is developed for workers of Oil and Gas industries and it suits well both for rig-chiefs jackets and trousers and for oil-pipeline workers uniforms.
Poseidon 300 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, Poseidon-300 has demonstrated the following results:
- S = 0,50 – Shielding factor – PASS
- t50 = < 0,01 – Decay half time – PASS
It means that when tested, Poseidon-300 fabric dissipated (lost) its electrostatic charge in less than 0,01 second. So it’s 400 times better, than EN 1149-5 requirements.
