BS 7507:1995

This standard BS 7507:1995 Specification for malleable wires for use as sutures and other surgical applications is classified in these ICS categories:

• 11.040.30 Surgical instruments and materials

This International Standard specifies the dimensions and mechanical properties of malleable wires for use as sutures and other forms of tissue and implant fixation in surgery, and gives test methods. The mechanical properties specified are tensile strength, elongation, and resistance to damage in bending and in torsion.

Surface finish is not covered by this International Standard.

NOTE 1 For such surgical applications, it is essential that the wire can be twisted or knotted without fracturing or developing cracks or crevices in its surface.

NOTE 2 Malleable wires may be used in close relationship to other implants. In these circumstances, it is important that stainless steel wire of compositions D and E (see ISO 5832-1) should only be used in relation to implants made of corresponding stainless steel, and wires made of high-nitrogen stainless steel should only be used in relation to implants of high-nitrogen stainless steel. This will reduce the possibility of galvanic corrosion occurring between the wires and implant.
