BS 6911-1:1988

This standard BS 6911-1:1988 Testing earth-moving machinery is classified in these ICS categories:

• 53.100 Earth-moving machinery

1.1 This International Standard specifies a procedure for calculating the volume of dozer blades. It is intended to be used for consistent comparisons of dozer blade capacities presented in commercial literature for tractors, as defined in ISO 6165. It is not to be used for predicting productivity of tractor dozers in actual field conditions or that might be observed in any specific applications. Such determinations need to consider other parameters, such as efficiency of the blade, tractor power, tractive effort, soil properties, terrain, operator technique and duty cycle.

1.2 This International Standard applies to all types of dozers that are mounted on all tractors defined in ISO 6747. This includes straight, angling, semi-U-, and U-blade configurations. It is assumed that the blade face is flat and vertical; the blade included volume is not considered (see Figure 1).
