Etna flame retardant fabric certified to EN 1149-5:2018

February 2020, our flame retardant fabric Etna has been successfully tested 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).

Etna flame retardant fabric is made of 350 gsm cotton with antistatic yarn and designed for use in Metallurgy and other industries. This fabric is best used for protective jackets, pants, overalls and other FR clothing.

Satin weave of Etna helps molten metal drops go off easily from the smooth surface of the fabric when used in fr clothing.

Etna 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, Etna has demonstrated the following results:

  • S = 0,53 – Shielding factor – PASS
  • t50 = < 0,01 – Decay half time – PASS

It means that when tested, Etna fabric dissipated (lost) its electrostatic charge in less than 0,01 second. So it’s 400 times better, than EN 1149-5 requirements.
