- Contact Heat (ISO 12127-1:2015) – performance level – F1
- Average threshold time (S): 9,5
ISO 12127-1:2007 specifies a test method for the determination of contact heat transmission. It is applicable to protective clothing (including hand protectors) and its constituent materials intended to protect against high contact temperatures. ISO 12127-1:2007 is restricted to contact temperatures between 100°C and 500°C.
| Performance level | Threshold time (s) | |
| Minimum | Maximum | |
| F1 | 5,0 | < 10,0 |
| F2 | 10,0 | < 15,0 |
| F3 | 15,0 | |
The performance requirements set out in ISO 11612:2015 are applicable to garments which could be worn for a wide range of end uses, where there is a need for clothing with limited flame spread properties and where the user can be exposed to radiant or convective or contact heat or to molten metal splashes.
FR-Fleece-280 is designed to use the softness and warmth of Fleece fabric with adding some extra features such as Heat and Flame Resistance. We use 60% Modacrylic fibers and 39% Cotton together with 1% Antistatic carbon fibers to get our 280gsm FR-fleece. The part of Modacrylic fibers interwoven with Cotton provides to the the whole fabric its flame resistance. FR-Fleece can be used as a middle layer or warmer for winter FR-clothing.

December 2019, our flame retardant fabric FR-Fleece-280 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).
FR-Fleece-280 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, FR-Fleece-280 has demonstrated the following results:
- S = 0,53 – Shielding factor – PASS
- t50 = < 0,01 – Decay half time – PASS
It means that when tested, FR-Fleece-280 fabric dissipated (lost) its electrostatic charge in less than 0,01 second. So it’s 400 times better, than EN 1149-5 requirements.
