本标准规定了手持式螺钉和拔管器的性能和安全要求，这些拔管器专门用于从螺纹开口处移除断裂的螺钉、管道、螺栓、螺柱和配件。仅适用于需要敲打拔取器以将其正确固定在被拆除的断裂管道或紧固件中的设计。因此，本标准不包括不需要敲打的设计，例如地螺纹拔取器。本标准旨在作为选择、测试和使用所涵盖手动工具的指南。本标准的目的不是规定制造细节。该标准还将作为制定手册和海报的指南，用于培训安全实践人员。本标准可作为国家当局或其他监管机构制定法律或法规的指南。

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.
