Foreword

This standard GB/T 1.1-2009 given rule drafting.

This revised standard adopts ISO 11143:2008 "dentistry amalgam separator" (in English).

This standard and ISO 11143:2008 The main differences are as follows.

--- Join the introduction of standard amalgam separator is used in conjunction with the dental unit in the form of instructions;

--- With GB 9706.1-2007 "Medical Electrical Equipment Part 1. General Requirements for Safety" (IEC 60601-1. 1988, IDT) on behalf of the For IEC 60601-1:2005 "Medical Electrical Equipment Part 1. General requirements for safety";

--- With GB/T 6682-2008 "analytical laboratory use specifications and test methods" (ISO 3696. 1987, MOD) instead of ISO 3696. 1987 "analytical laboratory use specifications and test methods";

--- On normative references, this standard has been adjusted technical differences, in order to adapt our technical conditions, the adjusted situation Focus is reflected in the status of Chapter 2, "Normative references", the specific adjustment is GB/T 9937 (all parts) instead of the ISO 1942 (All parts), the degree of consistency between the various parts of the following two criteria.

Introduction

Amalgam separator is a dental device for dental treatment centers from the trapped effluents carried amalgam particles, Thereby reducing the content of amalgam into the sewer system.

Separated amalgam particles can be used centrifugation, precipitation, filtration, or any combination of these methods.

Evaluation samples for testing the efficiency of the amalgam separator should be able to reflect the size of the dental treatment centers actual emissions of fine particles of silver amalgam Distribution. The standard test sample is based on the size of dental treatment center has been discharged wastewater amalgam particles Distribution Survey (see Appendix D) determined.

Test principle this standard amalgam separator efficiency. the discharge from the amalgam separator water collected in a container.

Then these contain amalgam separator does not live in the amalgam particles trapped water through a filter of known weight. Then close Set silver amalgam particulate filter placed in a desiccator dried at room temperature to a constant quality. So as to arrive amalgam separator collected The total weight of the microparticles to determine the collection efficiency.

This standard aims to standardize amalgam separator requirements and test methods for use with its form and not dental unit Specified. The separator can be equipped on the dental unit as a member, but also as a stand-alone device and dental waste water treatment center Exhaust system connection to use.

1 Scope

This standard specifies the requirements and test methods for dental equipment and dental treatment centers connected amalgam separator, provides Based on laboratory tests to be trapped amalgam level-based amalgam separator efficiency, as well as determining the efficiency of the test step Step, and provides dental amalgam separator safe operation requirements, marking requirements, requirements for use, operation and maintenance requirements. All tests are type tests described in this standard.
