Marking and Labeling7.1 All marking and labeling shall be legible.7.2 The instruments shall bear the following: (1) the manu-facturers (or contractors) name or registered trademark; (2)the country
16、 of origin (when the instrument is not manufacturedin the United States); and (3) other markings, as required, bythe purchaser or the manufacturer (contractor).7.3 The location of marking shall be on a suitable surface ofthe instrument.NOTE 2This specification is not intended to cover delicate tissu
17、eforceps such as those used in microsurgery or neurosurgery.NOTE 3Typical methods of modifying the working end of the forcepsis to use jaw inserts or to plasma deposit (flame plate) materials withimproved wear characteristics such as tungsten carbide or stellite. For thejaw insert methods, the inser
18、t is brazed to the jaw face with a uniformdeposit of silver solder that is free of crevices at all interfaces. For theflame plating method, a uniform layer of material is deposited that is 0.0046 0.001 in. (0.1 6 0.03 mm) thick.ASTM International takes no position respecting the validity of any pate
