This Standard specifies the requirements and the corresponding test methods for dental ceramic materials for fixed all-ceramic and metal-ceramic restorations and prostheses.
Le présent amendement modifie les paragraphes 7.2.2 et 7.6.4 de la norme NF EN ISO 6872, d'août 2015.
An error, which could lead in the test laboratory for testing the activity concentration of 238 uran to a misinterpretation, was detected and corrected. The radioactivity limit for dental ceramics was not changed. There is no change in the scope. Dental ceramic materials are very suitable for production of fixed dental restorations (e. g. crown, bridges) and removable dentures.
This International Standard specifies requirements for the contents of a technical file to demonstrate the fulfilment of regulatory requirements for a dental implant and any prefabricated part thereof which remains in the mouth after surgery.This International Standard is not applicable to instruments and other parts specifically made for the dental implant system but which do not remain in the mouth. However, documentation relating to these components may be included in the technical file.
This document determines a degree of firing to be implemented by the user. It represents a test method for adapting the firing program of a dental furnace by determining the degree of firing of fired test specimens for a dental ceramic. The test method is suitable for powdered dental ceramics according to ISO 6872, Type I. The test method enables monitoring of the temperature control in the dental furnace by evaluating the firing degree of a dental ceramic. The test method is also suitable for evaluating the reproducibility of the firings in a dental furnace or for comparing several dental furnaces.
This Standard specifies general requirements for instruments and related accessories to be used specifically in dental implantology in the craniofacial area. These requirements apply to instruments when they are manufactured. This includes instruments for single-use and reusable instruments.This International Standard applies to instruments used on the patient which are manually driven instruments and to instruments which may be connected to power-driven systems, but does not apply to the power-driven systems themselves.With regard to safety this International Standard gives requirements for intended performance, design attributes, selection of materials, design evaluation, manufacture, sterilization, packaging and information to be supplied by the manufacturer.
This International Standard gives requirements and test methods for determining the compliance of dental casting investment, dental brazing investment, dental pressable-ceramic investment and dental refractory die materials used in the dental laboratory, regardless of the composition of the refractory powder, the composition of the binder, or the particular application. This International Standard classifies such products into types and classes, according to their intended use and the burn-out procedure recommended by the manufacturer. It also gives requirements for marking, labelling and manufacturer's instructions. It specifies requirements for the essential physical and mechanical properties of the products and the test methods to be used for determining them.
