All materials used on the exterior and touchable surfaces of dental equipment are subject to aerosols, splashes and droplets during normal use. Pollution. When disinfected with the relevant disinfectant recommended by the dental equipment manufacturer, these materials should be able to withstand this disinfection without Degenerate or discolored. Dental Dental Equipment Surface Materials Resistance to chemical disinfectants

1 Scope

YY/T 1400 is the test that decides whether a dental unit survives its own hygiene routine. It specifies how to determine the resistance of materials used on dental equipment surfaces to chemical disinfectants: the plastics, coatings and upholstery that are wiped down between every patient, several times an hour, for years. Disinfectant damage shows as crazing, discolouration, tackiness or loss of strength, and it is the most common reason a chair or a delivery unit looks worn long before it stops working. The method gives a manufacturer a way to qualify a surface material and a purchaser a way to compare claims. For a manufacturer of dental units, cabinetry or handpiece housings selling into China, this is the standard behind a disinfectant compatibility statement.

This standard specifies three test methods for determining the characteristics of chemical disinfectants that are expected to require disinfection of the external surface of dental equipment. Soaking test, spray test, contact test. The choice of which test method to use is determined by the experimenter. This standard does not address the effectiveness of disinfectants in bacteria, viruses and fungi. This standard does not specify the test material in the resistance reagent test, the stress on the determination of the possible impact.

4 Sampling

All tests described in this standard are type tests. As far as possible from the dental equipment on behalf of the representative of the sample, a complete test. The sample is as flat as possible. The following sampling side Choose one of the law.

a) the use of new parts of dental equipment;

a) it is not possible to use standard samples and samples made from semi-finished products (eg thick plates, sheets or balls);

c) Specimens may also be made by cutting (eg, cutting or sawing) unprocessed parts or semi-finished products, but requiring new edges and new surfaces of the specimen to be The original surface of the same nature. On the new edge and the new surface of the area formed should be protected, the new area should account for the sample area A smaller proportion. All samples should be free of dirt and grease.
