Madeira-320 AS flame retardant fabric updates EN 1149:2018

May 2019, our cotton flame retardant fabric Madeira-320 AS 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).

Madeira-320 AS is a flame-retardant cotton fabric with antistatic yarn with 320 gsm density, with a classic twill 3/1 weave. It’s an Antistatic version of our best-selling Madeira-320 pure cotton flame-retardant fabric. Made of natural fibre, it is comfortable to wear and at the same time Madeira-320 AS safely protects from the risks of flash fire and electric arc. Madeira-320 AS FR-fabric is certified to EN 1149 Antistatic standard. This prevents accumulating ESD charges and make it safer to use this fabric for everyday flame-retardant workwear such as FR-pants, FR-jackets, FR-bibs, and FR-overalls.

Madeira-320 AS 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 = 0,61 – Shielding factor – PASS
  • t50 = < 0,01 – Decay half time – PASS

It means that when tested, Madeira-320 AS fabric dissipated (lost) its electrostatic charge in less than 0,01 second. So it’s 400 times better, than EN 1149-5 requirements.
