Common use of Apparatus Clause in Contracts

Apparatus. 10.4.1. Combustion chamber (figure 15), preferably of stainless steel, having the dimensions given in figure 16. The front of the chamber contains a flame-resistant observation window, which may cover the entire front and which can be constructed as an access panel. The bottom of the chamber has vent holes, and the top has a vent slot all around. The combustion chamber is placed on four feet, 10 mm high. The chamber may have a hole at one end for the introduction of the sample holder containing the sample; in the opposite end, a hole is provided for the gas-supply line. Melted material is caught in a pan (see figure 17) which is placed on the bottom of the chamber between vent holes without covering any vent hole area. 10.4.2. Sample holder, consisting of two U-shaped metal plates or frames of corrosion- proof material. Dimensions are given in figure 18. The lower plate is equipped with pins and the upper one with corresponding holes, in order to ensure a consistent holding of the sample. The pins also serve as measuring points at the beginning and end of the burning distance. A support shall be provided in the form of heat-resistant wires 0.25 mm in diameter spanning the frame at 25-mm intervals over the bottom U-shaped frame (see figure 19). The plane of the lower side of samples shall be 178 mm above the floor plate. The distance of the front edge of the sample holder from the end of the chamber shall be 22 mm; the distance of the longitudinal sides of the sample holder from the sides of the chamber shall be 50 mm (all inside dimensions). (See figures 15 and 16). 10.4.3. Gas burner
