MOTOR 1. SCOPE The test method defined by this specification is fogging for interior parts. 2. OBJECT PARTS The object parts of fogging shall be sheet, leather, cloth, mold parts, nonwoven, carpet, foam, pad and conform to drawing. 2. TEST STANDARD CONDITION Unless otherwise specified, the normal state of laboratory shall be at 20±2℃ and 65±5% relative humidity. 3. SAMPLING of SPECIMEN 3.1 Specimen : Specimen shall be sampling at finished product in principle. 3.2 Size and thickness of specimen 3.2.1 Specimen size : circular specimens 70 ㎜ in diameter. 3.2.2 Specimen thickness 1) Thickness shall be that of finished products 2) In case 20 mm or less thickness, specimen shall be used for test by actual thickness of product. If the thickness of finished products exceeds 20 mm, cut uniformly to 10 mm thick. 3.3.3 In case finished products being not plane(ex: PVC mold part), specimen shall be used for test by 10 ±2 g weight.

4. TEST METHOD 4.1 Specimen state Specimens shall be allowed to stand at least 24 h in the above normal state before test. 4.2 Equipment Use the following equipments. 1) Fogging tester : An oil bath and breaker with cover as shown in FIG. 1. 2) Measuring instrument(Integral sphere type light transmittance meter) : A device shown in Fig. 2.
4.3 TEST METHOD Prepare three circular specimens 70 mm in diameter.
Place a specimen with its skin upward in
a breaker of the fogging tester as shown in Fig. 1. Place a steel cover having a 40 mm diameter hole over the breaker. Place a glass plate(fogging 1%, or less) 50 mm wide, 50 mm long, and 3 to 5 mm thick over the hole.
Heat in the oil bath at 100 ℃ for 5 h.
Remove the glass after heating and measure the fogging attached on the glass at three locations in the center in accordance with the procedure in Table 1, using the device(Integral sphere type light transmittance meter) shown in Fig. 2. Table 1 Procedure Glass plate
