ASME B107.46:2004

Anotace textu normy ASME B107.46:2004 :

This Standard provides performance and safety requirements for handheld screw and pipe extractors that are intended specifically for removing broken screws, pipes, bolts, studs, and fittings from threaded openings. It is intended to cover only those designs that require striking of the extractor to seat it properly in the broken pipe or fastener being removed. This Standard, therefore, does not cover designs that do not require striking, such as the ground thread extractor. The Standard is intended to serve as a guide in selecting, testing, and using the hand tools covered. It is not the purpose of this Standard to specify the details of manufacturing. The Standard is also meant to serve as a guide in developing manuals and posters for training personnel in safe practices. This Standard may be used as a guide by state authorities or other regulatory bodies in the formulation of laws or regulations.
