Dentistry - Base polymers - Part 1 : denture base polymers

ISO 20795-1:2013 classifies denture base polymers and copolymers and specifies their requirements. It also specifies the test methods to be used in determining compliance with these requirements. It further specifies requirements with respect to packaging and marking the products and to the instructions to be supplied for use of these materials. Furthermore, it applies to denture base polymers for which the manufacturer claims that the material has improved impact resistance. It also specifies the respective requirement and the test method to be used.ISO 20795-1:2013 applies to denture base polymers such as those listed below: poly(acrylic acid esters); poly(substituted acrylic acid esters); poly(vinyl esters); polystyrene; rubber modified poly(methacrylic acid esters); polycarbonates; polysulfones; poly(dimethacrylic acid esters); polyacetals (polyoxymethylene); copolymers or mixtures of the polymers listed in 1 to 9.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
