DIN 4102-17 Fire Behavior of Building Materials and Components - Determination of the Melting Point of Mineral Fiber Insulation Materials

EUROLAB laboratory provides testing and compliance services within the scope of DIN 4102-17 standard. This part of the DIN 4102 standard defines fire behavior classes for building materials and specifies requirements and testing. Methods for each class are determined separately.

This standard applies to sheet materials (including boards and plates), composite materials, material assemblies, coatings, insulation, coatings, pipes and fittings, decorative materials, curtains and other materials suspended from ceilings, fire retardants and intumescent coatings. These materials are defined as construction products (Bauprodukte) in the German Länder building regulations.

The classification specified in this standard serves to evaluate the fire behavior of materials alone or in combination. Fire behavior depends not only on the nature of the material, but also on its shape, surface properties, density, processing and combination with other materials, including any binder. These factors should be taken into account while preparing the tests, selecting the sample, and making the evaluation.

DIN 4102-17 Test Procedure

Preheat the oven to (750t10) °C; this temperature will remain constant within t1 °C without the need for readjustment for at least ten minutes prior to the test. The energy entering the heating element will remain constant throughout the test. Suspend the sample in the heating tube with its center aligned with the thermocouple connection. The original sample surface or - in the case of asymmetrical samples - the least suitable surface in terms of fire behavior is to face the thermocouple, which will be placed in the middle of the width of this surface.

Multi-layer specimens will be hung as specified. While suspending the sample, do not open the oven door for more than five seconds. The test time begins when the lower edge of the sample passes the upper edge of the heating tube. Leave the sample in the oven until the maximum oven temperature is reached and for at least 15 minutes.

If the initial furnace temperature still has not risen after 30 minutes, only one sample needs to be tested. the point at which the maximum temperature is reached (but not more than 90 minutes), provided that the other samples behave similarly during the first 30 minutes.

If the pilot flame is extinguished by gases released by the sample, it should be immediately re-ignited with a burner that produces a gas flame of approximately 20 mm in length. If the first attempt fails, further attempts will be made every 15 seconds. The oven door will not be opened during the test. The holes in the bottom plate will be cleaned before each test.

Among the services provided by our organization within the framework of material testing services, there are also DIN 4102-17 standard tests. Do not hesitate to contact our laboratory EUROLAB for your testing and certification requests.
