适用范围

This part of ISO 7785 specifies requirements and test methods for straight and geared angle handpieces. These handpieces are operated by electrical or air driven motors. In addition to these specified re-quirements, there are several other essential as-pects of the materials, construction, and general design of handpieces which cannot be objectively specified or assessed. They are considered to be complied with if the series of objectively verifiable requirements are fulfilled. NOTE 1 As handpieces are complex constructions, it is not possible to specify all details even though they are important. In these latter cases only general specifi-cations are possible, and it is the responsibility of the manufacturer to make the relevant decisions to achieve a safe and reliable product.
