YY/T 0905.2-2013Dentistry—Plant area equipment - Part 2: Compressor systems (English PDF)

Foreword

YY/T 0905 "Dentistry field devices" is divided into two parts.

--- Part 1. pumping systems;

--- Part 2. compressor system. This section is YY/T Section 20905 of. This section drafted in accordance with GB/T 1.1-2009 given rules.

The partial modification of the use of ISO /T S22595-2.2008 "Dentistry field equipment - Part 2. compressor system" (in English).

This part of ISO /T S22595-2 with.2008 main differences are as follows.

--- According to GB/T 1.1-2009 some formatting has been modified;

--- In order to facilitate understanding, increasing the "compressor head" Definition;

--- With GB 9706.1-2007 "Medical Electrical Equipment Part 1. General requirements for safety (IEC 60601-1. 1988, IDT)" Generation For IEC 60601-1:2005 "Medical Electrical Equipment Part 1. General requirements for safety";

--- With GB/T 4980-2003 "Determination of displacement of the compressor noise" instead of GB/T 23282-2009 "Metalforming Machinery NOISE Power level measurement method "(ISO 3746:1995, NEQ);

--- Increased 5.1 Electrical Requirements "If the compressor unit installed within the range of 1.5m from the patient (such as noise reduction cabinet), the GB 9706.1-2007 apply. " --- For other international standards cited in this section, if it has converted to our standards, replace the International Standard In this section, references to The corresponding number of national or industry standards, and in Part 2 of this chapter marked on relationships.

--- According to the international system of units, the unit of pressure 5.2.1 by the "bar" to "MPa (bar)".

Introduction

This section applies to dental compressor system and working conditions, but also applies to all other auxiliary equipment installed in the field.

Compressor system consists of a compressor unit, air lines, fittings and shut-off valves and other components.

1 Scope

This section YY/T 0905 applies to dental air compressor system.

This section is used to give the dental unit, dental instruments and dental laboratory to provide a source of compressed air and compressor unit performance experiment method.

Compressor unit includes a compressor head, air tank, air dryer system, condensate valves, pressure switches, valves, pipes, fittings.

This section also gives dental air fittings, piping and valves and other compressor units use environmental norms Administration Guide.

This section only applies to the main line of compressed air before the point of attachment.
