The exposed area of the specimen shall be at least 51 mm (2 in.) wide and 305 mm (12 in.) long, unless the actual size used in the car is smaller. The specimen shall be mounted in a metal frame so that the two long edges and the upper edge are held securely. In the case of fabrics, both the warp and fill direction of the weave shall be tested to determine the most critical flammability conditions. The specimen shall be no thicker than the minimum thickness to be qualified for use in the car. The specimen shall be cut from any location in a fabricated part however, fabricated units, such as sandwich panels, shall not be separated for test. Materials shall be tested either as a section cut from a fabricated part as installed in the car or as a specimen simulating a cut section, such as a specimen cut from a flat sheet of the material or a model of the fabricated part. suspension member, as required in 2.20.11 (see 8.3.12).escalator steps, as required in 6.1.3.5.7 and moving walk pallets, as required by 6.2.3.5.4 (see 8.3.1 and 8.3.11).safety nut and speed-limiting device of screw column elevators, as required in 4.2.11.2 (see 8.3.1 and 8.3.10).hydraulic overspeed valves, as required in 3.19.4.7 (see 8.3.9).test method for evaluating room, fire growth, contribution of textile wall covering, as required in 8.7.2.14 (see 8.3.7 and 8.3.8). ![]() elastomeric buffers (see 8.3.1 and 8.3.13).hydraulic control valves as required in 3.19.4.6 (see 8.3.1 and 8.3.5).entrance fire tests as required by 2.11 (see 8.3.4).car door or gate electric contacts, and car door interlocks as required in 2.14.4.2 (see 8.3.1 and 8.3.3).hoistway door interlocks, hoistway door combination mechanical locks, electric contacts, and hoistway-door electric contacts, as required in 2.12.4 (see also 8.3.1 and 8.3.3).car and counterweight oil buffers, as required in 2.22.4.7 (see also 8.3.1 and 8.3.2).
