State Food and Drug Administration issued
Foreword
This revised standard adopts the International Standard ISO 7488.1991 "Dental amalgam blending device."
This standard and ISO 7488.1991 The main differences are as follows.
The requirements for electrical safety standard GB 4793.1-2007 "measurement, control and laboratory safety requirements for electrical equipment Part 1
Score. General requirements "instead of ISO 7488.1991 is referenced in IEC 335-1. 1976 (IDT, GB 4706.1" Household and similar electrical appliances
Safety - Part 1. General requirements ").
Instead of the standard YY/T 0273-1995 "dental amalgam blending device."
Compared with the standard YY/T 0273-1995 The main changes are as follows.
a) The full implementation of electrical safety standard GB 4793.1-2007, YY/T 0273-1995 only in the implementation of GB 9706.1-1995
"Protective grounding impedance, dielectric strength and continuous leakage current" 3;
b) The standard delete environmental testing requirements specified by the companies in their product standards;
c) The standard delete noise, appearance, inspection rules and other requirements prescribed by enterprises in their product standards.

Introduction
Blending electric amalgam is mainly used to refer to silver alloy powder and mercury are mixed through vibration and provide sufficient mechanical energy to amalgamation, too
Dental amalgam to the machine, but will also be used mixed with other dental materials.
Some amalgam blending is equipped with a special plastic capsule and repeated use, used to hold silver alloy powder and mercury, although in use or tested
Cheng, the plastic capsule itself should be seen as part of the blending, but does not require it relates to this standard in the future, if necessary, may
This special capsule separately standards.
Some blending amalgam alloy powder or appliance installed partakers mercury or both may dispensing function. This machine in addition to the dispensing part, should also be the root
According to the present standards for testing.
Dental amalgam blending device
