YY 1070-2008Dental baseplate/modelling wax (English PDF)

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.

1 Scope

This standard dental Keji Tuo from natural and synthetic waxes mainly used for making dentures composition/wax model of classification and requirements of Regulation Set, and provides the appropriate test methods to determine the specimen under test meets the requirements of this standard.
