        to determine the fire resistance by the fire hazard test
        in accordance with IEC 60695 Part 2 Section1 / 1994-03
        and further standards and regulations listed in the STANDARDS SCHEDULE T
        03e
        The test procedure is used to examine the fire resisting
        properties of products if, during the application or in the
        case of a fault, heated or glowing parts could be
        considered as a short-time ignition source. Loose
        connections or bad contacts cause punctually high
        temperatures on electrical articles, their components
        and their parts. Attention should also be paid to the fire
        risk in connection with textile seat coverings, table-
        cloths, or curtains, e.g. after coming into contact with a
        lighted cigarette. For this reason, prototypes of all
        articles which could be a source of danger if they con-
        tact with ignition sources should be subjected to the
        Glow-wire Test.
        Test Apparatus
        The ignition source is imitated by an electrically heated
        wire loop against which the sample is pressed with a
        constant force. A miniature jacket thermocouple serves
        as a sensor for the loop temperature.
        The sample has to be fastened to a carriage on which, by means of a tensioning cord, a weight
        with a force of 1 N is effective in the direction of the wire loop. Scales enable the reading of the
        flame height and the depth of penetration. Approx. 200 mm below the wire loop a board of pine
        wood, covered with a layer of tissue paper, is mounted. This device enables to judge the danger
        of a fire spreading through burning drops or glowing parts falling from the sample.
        Test Method
        The specimen and, if necessary, a base shall be attached relative to the wire loop in such a way
        to represent the most unfavourable practical case. The scales of the measuring device shall be
        adjusted and the penetration depth of the loop shall be limited by the adjustable stop. After
        returning and covering the specimen the loop shall be heated up to the specified temperature.
        When the loop has maintained the testing temperature for at least 60 seconds, the specimen
        can be briskly led up to the loop. From the moment of contact, an operation time of exactly 30
        seconds must be kept. Then the penetration depth is read and the specimen is slowly returned
        to its starting position. During and after the operation the burning behaviour of the specimen and
        the tissue paper on the wooden board has to be observed.
