EN469 TEST
METHOD
Performance levels：
．Level 1
Lower level of protection which meets the minimum performance requirement of outerdoor firefighting and peripheral support operation.
Not applicable to structural firefighting and the risk that the wearer may face in the firefighting.
．Level 2
Higher level of protection which meets the minimum performance requirement of structural firefighting and disaster relief operations.
When there are both level 1 and level 2 performance in the heat and flame protection section of a firefighting suit, the suit should be classified as level one and not allowed for structural firefighting. The wearer and purchaser should select firefighting suits at the suitable protection level based on disaster relief risk assessment.

The material shall be tested by applying the test flame to the surface for 10 seconds to stimulate the accidental flame contact in a fire scene.
Need to meet below requirements in order to protect wearers effectively.
| Tested material | Test method | EN 469:2020 test requirement |
| Outer materials | EN ISO 15025 | ．EN ISO 14116 index 3 |

| Wristlet materials | ．No flaming or molten debris | |
| Hardwear | ．Afterflame ≦ 2s | |
| Larger labels | ．Afterglow not to spread |
Contact Heat is only required for Level 2 garments.
The test is executed before and after pre-treatment by 5 times washing. Test method is EN ISO 12127-1:2015. When the contact temperature reaches 250°C, the time it takes for the "inside" temperature of the assembly to rise by 10°C is measured. And the time required is at least 10 seconds.
Contact heat testing requires the time at least 10 seconds. The longer the firefighting suit lasts for testing, the more safety the firefighting suit provides to firefighters.

Speciman is exposed horizontally to an intensive heat flux of 80kW/m².
HTI12 is the time to reach temperatures associated with first degree burns of human skin (PAIN).
HTI24 is the time to reach temperatures associated with second degree burns of human skin (BLISTERS).
HTI24-12 is the reaction time between +12°C and +24° C.
ISO 9151:2016 test indicates 2 performance levels in the EN 469:2020 :
X1 - the lower performance level
X2 - the higher level.
Firefighters are often exposed to confined environments with extremely high temperature which might be the heat emitted by direct flame. When they feel pain (usually the back skin), it's an alert of first degree burns, they should prepare to evacuate before the temperature reaches second degree burns that paralyzes their mobility.
Important : The heat transfer index should not be taken as a measure of the protection time given by the tested materials under actual use conditions.

Firefighters are often exposed to confined environments with extremely high temperature which might be the heat convected by burnt substances. When they feel pain (usually the back skin), it's an alert of first degree burns, they should prepare to evacuate before the temperature reaches second degree burns that paralyzes their mobility.

6.2.1.6 Heat resistance
When tested according to ISO 17493:2016 at a temperature of (180 ± 5) °C for an exposure time of 5 min, each material used in the garment assembly shall not ignite or melt and shall not shrink more than 5 % in either machine or cross direction. Each layer of the material shall be tested separately. If a specimen of sufficient size cannot be taken it may be fixed on the carrying material as used in the garment.
When tested according to ISO 17493:2016 at a temperature of (180 ± 5) °C for an exposure time of 5 min, hardware of the type(s) intended to be used in the finished garment, shall remain functional after this test. Five minutes after removal from the testing oven any closure system for doffing shall be capable of being opened once.

The combination of materials in a component assembly shall be prepared so that all the layers of the material are sewn together around all four edges of the test specimen. One test specimen shall be tested. Pre-treatment will be carried out as an assembly. Once completed, all components will be separated and measured individually.
The test on performance of the component assembly shall not be performed if each single layer of the assemblymeets individually the dimensional change requirements.
Sizing should take into account the expected shrinkage and the expectation that clothing will be worn underneath the EN 469 garment (e.g. summer and winter time).

The requirements for water vapour resistance (Ret) shall be achieved by testing three specimens after pre-treatment of either the component assembly or the (multilayer) garment assembly. Anti- wicking barriers, retro-reflective, fluorescent or combined performance material(s) are excluded from this requirement.
NOTE 1 Accessories such as anti-wicking barriers, retro-reflective, fluorescent layers, labels or pockets can reduce the water vapour transmission.
NOTE 2 Annex E provides another test method on physiological impact – sweating torso that will provide additional information on comfort.
