This ballot cleans up Figure 1, which contains many meaningless dimensions, such as the length and width of the cabinet, which appear to have been based on the cones commercially available when the standard was first written. These have been removed. This ballot contains no technical changes, but is merely intended to make the apparatus description clearer and acknowledge different physical arrangements for the instrument. Figure 1 lists the distance from the baseplate of the cone fire model to the bottom of the exhaust hood as a critical dimension. This is meaningless, as different load cells may have different dimensions. Thus, this dimension is deleted and a more meaningful dimension (distance from the specimen surface to the bottom of the exhaust hood), is added. (This dimension includes a large tolerance to accommodate testing at different separations. 25mm and 60mm are the most common separations used).
