Criteria for the design, dimensions and performance of standard and miniature frames. Gives tensional test procedures.

This British Standard specifies requirements for the design, dimensions, and performance of hand hacksaw frames to take blades of nominal length 300 mm complying with BS 1919 and of miniature hand hacksaw frames to take blades of nominal length 146 mm complying with BS 6271.

NOTE 1 Materials are at the discretion of the manufacturer provided that design and performance criteria are met. Normally the working parts are in steel and the handles in either die cast alloy, plastic injection mouldings or shaped wood.

NOTE 2 Restrictions on the use of materials for use underground and in other potentially explosive atmospheres are given in Appendix C.

NOTE 3 The titles of the publications referred to in this standard are given on the inside back cover.
