ISO 4823-2015 pdf free.Dentistry一Elastomeric impression materials.
This International Standard specifies the requirements and tests that the state-of-the art body of knowledge suggests for helping determine whether the elastomeric impression materials, as prepared for retail marketing, are of the quality needed for their intended purposes.
NOTE This International Standard does not address possible biological hazards associated with the materials. Therefore, interested parties are encouraged to explore ISO 7405 and ISO 10993 for assessment of such hazards.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1942 and the following apply.
3.1 consistency degree of firmness with which particles of a material, prepared for use, cohere so as to allow the material to flow, or resist flow, as required to achieve the purpose for which it is intended
3.2 elastic recovery test
DEPRECATED: compression set
DEPRECATED: permanent deformation
DEPRECATED: recovery from deformation (elastic impression materials) method of determining whether the materials possess the elastic properties required to recover adequately after deformation occurring when the materials used for forming impressions are removed from the mouth
3.3 extrusion mixing method by which two or more material components are extruded simultaneously from their separate primary containers through a special mixing tip from which the material components emerge as a homogeneous mixture
4 Classification
Materials covered by this International Standard are classified according to the following consistencies determined immediately after completion of mixing according to the manufacturer’s instructions (see 53):
— Type 0: putty consistency;
— Type 1: heavy-bodied consistency;
— Type 2: medium-bodied consistency;
— Type 3: light-bodied consistency.
5 Requirements for packaging, labelling, and information in manufacturer’s instructions
5.1 Packaging requirements
No packaging requirements are specified in this International Standard, but it is important for manufacturers to take into account that the packaging should be such that it will not contaminate or permit contamination of ingredients of the material components during recommended storage conditions. Structure of the primary packaging should also be such that no leakage or inadvertent extrusion of the contents can occur during storage and such that the containers will not rupture during use of the extrusion methods recommended by the manufacturer.ISO 4823 pdf download.
