The work of preparing International Standards is normally carried out through IsO technical committees. Each member body interested in a subject for which a technical committee has been non-governmental, in liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. IsO shall not be held responsible for identifying any or all such patent rights. ISO13078 was prepared by Technical Committee ISO/TC 106,Dentistry, Subcommittee SC 2, Prosthodonticmaterials. ii ISO13078:2013(E) Introduction and enamel materials to the respective compatible substructure materials. Dental furnaces are also used for other applications such as oxidizing metallic substructures in preparation for porcelain firing, for melting pressable ceramics, for stain and glaze firing, etc. According to the current state of the art, the temperature of this process lies between600°C and1050°C The firing result obtained is influenced by the accuracy of the actual temperature, which may be influenced by construction types of the dental furnaces currently on the market. Despite the fact that different dental furnaces can have identical digital external displays, different results regarding discoloration and changed aesthetics of the dental ceramic restoration. This International Standard levels the currently existing differences between the final calibration of the dental in an identical way) of the temperature control in the firing chamber by means of a thermocouple at e.g. 8oo °C. Alternatively, the verification of the process can be carried out using the thermocouple at 70o °C or 900 °C. @ ISO 2013 - All rights reserved raftional Organization for Standardizatior 01, User=sharabiani, shahramts INTERNATIONALSTANDARD ISO13078:2013(E) Dentistry Dental furnace Test method for temperature measurementwithseparatethermocouple 1 Scope This International Standard specifies a testmethod forthe calibration of dentalfurnaces that are suitable fo the heat treatment of silica-based dental ceramic restorations in the temperature range between 6oo °C and 1 o5oC.This International Standard does not include furnaces intended tosinter zirconium oxide-frameworks (in the temperature range of 1 350°C or higher). 2 Normative references The following referenced documents are indispensable for the application of this document.
