YY/T 0725-2009Dental equipment—Connections for supply and waste lines (English PDF)

Foreword

All aspects of this standard are recommended.

Introduction

In the dental unit with a treatment center, people continue to improve its design and equipment configurations to meet the requirements of modern dentistry. different Treatment machine manufacturer and model, its connection size and relative position of the facility are also different.

Equipment selection, especially in large installations of equipment selection, in order to determine the layout of the pipeline may have to be good at an early stage of construction The building was not in accordance with the appropriate equipment needed to choose. When after installing a replacement device, often to transform the main line. By Facilities layout standardization, to avoid the appearance of these difficulties, and to ensure that the pipeline contractor for proper facility requirements.

This standard is not intended to specify equipment should be within the scope of the use of dental surgeries, but the mutual position of the device will make provision. Dental equipment is connected to the exhaust pipe
