Foreword
All technical contents of this standard is mandatory.
This standard is identical with ISO 12163.1999 "Ke Jituo tooth/wax model."
Ke Jituo process tooth/wax model is mainly used for making dentures in the laboratory for use in the present standard does not involve their biological evaluation.
This standard is based on ISO 12163.1999 redrafted.
This standard and ISO 12163.1999 and the main difference between the following reasons.
--- Delete international standard "Preface" and "Introduction";
--- Cancel reference. Because this standard does not address biological evaluation content.
This standard replaces and repealing YY 91070-1999 "dental wax model" (original ZBC33025-1989).
This standard and YY 91070-1999 "dental wax model" (original ZBC33025-1989) the difference between.
--- Classification is different. The standard wax into three categories, YY 91070-1999 divided into two categories.
--- Rheology. This standard wax rheology requirements in YY 91070-1999 "dental wax model" to plastic deformation in 4.6
Different requirements. The test temperature and rheology values are not the same.
--- YY 91070-1999 "dental wax model" in the following clauses in this standard does not require.
1) 4.3 specification model wax;
2) 4.4 wax color is pink;
3) 4.5.2 porcelain dental wax and synthetic resin teeth adhesion, retention performance;
4) 4.7 is not brittle and break at a specific temperature performance;
5) 4.8 waxes linear shrinkage.
This standard was proposed by the State Food and Drug Administration.
This standard by the National Standardization Technical Committee of Dental Materials and Devices and equipment.
This standard by the State Food and Drug Administration Peking University Medical Device Quality Supervision and Testing Center is responsible for drafting.
The main drafters of this standard. Lin Hong, Sun Zhihui, Zheng Gang, HE Ming Ming.
