EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 7176-16 testing. EN ISO 7176-16 specifies the requirements and test methods for assessing the resistance to ignition by the match flame equivalent of all stance support devices provided, whether as part of a wheelchair or seating system. EN ISO 7176-16 determines only the ignition resistance of the devices under test, not the flammability of the entire wheelchair.
The development of an ISO standard on the ignition resistance of structural components has not yet begun. The most likely sources of ignition are proximity to a heat source such as an electric radiator or a household fire, or a heat source such as a match or cigarette falling on the structure.
This part of EN ISO 7176 is primarily concerned with the resistance of a wheelchair's postural support devices to ignition. These typically include arm supports, sling seats, back braces, lower leg braces, foot braces, side braces, head braces, etc. includes.
The most likely source of ignition is an open flame source that falls on the surface of the component or in the spaces between surfaces. Consequently, this part of EN ISO 7176 is written about the resistance to an ignition source equivalent to a lit match in contact with a test sample of an assembly of composite materials of the tiled part in both the vertical and horizontal directions. This part of EN ISO 7176 replaces EN ISO 7176‑16, since EN ISO 7176‑16 concerned only the upholstered parts of the wheelchair and was originally based on furniture test methods and requirements and is therefore suitable for clinically oriented components in the wheelchair. it wasn't.
The daily use of a wheelchair includes cyclic loading of its materials, movement of materials, washing, cleaning, etc. may affect its resistance to ignition. Manufacturers will often consider these effects as part of their risk assessment when selecting materials for wheelchairs. products to minimize the effects of this normal use. However, this part of EN ISO 7176 can be found in used parts etc. test specimens indicate new or unused parts.
This part of EN ISO 7176 describes the testing of an assembly consisting of composite materials used in a wheelchair component because the ignition resistance of these materials alone can be quite different than when assembled as a compound. Therefore, the test results according to this part of EN ISO 7176 do not give any indication of the ignition resistance of any of the individual materials of the stance support device.
