Its review throughout 2015/16 will lead to numerous useful improvements

The requirements in this standard provide a framework for control of manufacture

The circular cross-section for precision applications with specified outside diameter D ≤ 150 mm

The requirements of this standard for the strength and pressure resistance of the extinguisher bodies are more stringent than those specified for the otherwise similar Group 1 containers in BS 3914:1991
