Introduction

Dental investment material and other refractory materials are widely used in dental laboratory. In the past, based on the binder system used or special Given application developed five different international standards. This standard specifies the dental casting, brazing refractory embedding material and refractory die material for Performance requirements and test methods, without considering the type of binder system or a particular purpose.

This standard embedding material in accordance with the intended use were classified, according to the recommended classification process heating.

This standard does not include expansion of quantitative requirements cured. However, if combined with plaster casting investments need to measure the expansion rate of curing can be The test procedure adopted YY 0462-2003 "dental plaster products" given. The test procedure is not recommended for phosphate binders casting investments material. Dentistry casting investments and refractory die material

1 Scope

This standard applies to dental casting, brazing refractory embedding material and refractory die material, does not consider the type of system or a specific binding agent use.

The use of standard type according to the intended purpose of embedding material and classified according to the manufacturer's recommended heating process.

This standard specifies the basic physical and mechanical performance requirements and the corresponding test methods for these materials.

This standard also includes information and instructions on the packaging accompanying each request.
