35、 70 mm.NOTE This allows the dental rubber dam or a special dental rubber dam frame combination to be inserted deep enough in order to punch holes at any desired position.Test in accordance with 5.2.4.6 Spring type mechanism4.6.1 Spring type mechanism for holding the hole punch openIn its passive sta

36、te, the hole punch for dental rubber dam shall be opened, by means of a spring type mechanism, wide enough to ensure a distance of at least 2,5 mm between the tip of the punch and the face of the die plate.Test in accordance with 5.2.DIN EN ISO 16635-1:2014-09 EN ISO 16635-1:2014 (E) 7 4.6.2 Die pla

37、te mechanism for the engagement of the die plateThe die plate shall be provided with a mechanism which ensures its engagement in defined positions in order that the punch always makes contact with the holes at their centres.NOTE This is usually achieved by means of a spring mechanism.Test in accorda

38、nce with 5.1.4.7 MaterialsThe hole punch shall be made of corrosion resistant martensitic stainless steel 4021-420-00-I (X20Cr13) and 4034-420-00-I (X46Cr13) in accordance with ISO 15510.The die plate shall have a hardness of 48 HRC to 55 HRC or a Vickers hardness of 600 HV1 to 720 HV1.Test the Rock
