Introduction

This standard specifies the requirements for the optical radiation value of the light curing machine in the wavelength range of 200nm~385nm and the wavelength range above 515nm.

And test methods. For the 385 nm to 515 nm wavelength range, no minimum value is given. 385nm to 515nm wavelength range value Not less than the manufacturer's specified value.

This standard uses a wavelength range based on a cut-off filter. Therefore, the wavelength range of 200 nm to 385 nm includes not only the ultraviolet range, It also includes a near-blue light range with a wavelength around 380 nm. The wavelength range of 385 nm to 515 nm is considered to be the wavelength range of photocuring.

The wavelength range of 515nm~1100nm is the detection limit of the detectors involved in this standard. The test methods provided in this standard cannot be given absolutely.

The logarithmic value does not reflect the energy similar to blackbody radiation. The data obtained is not a true radiance value, but a test provided using this standard.

The value obtained by the method. However, the data obtained by these methods should be used in conjunction with this standard.

This standard cites the general standard for medical electrical equipment safety GB 9706.1, correspondingly, the applicable place marked GB 9706.1 corresponding chapter Article number. Dentistry light curing machine

1 Scope

This standard specifies that in the wavelength range of 385nm~515nm, it is used to irradiate and cure dental clinical polymer-based repair materials. The requirements and test methods for the light curing machine.

This standard applies to quartz tungsten halogen lamps and light-emitting diode (LED) lamps. The light curing unit can be powered by an internal power source (rechargeable battery) or Use a connected external power supply (network power supply). This standard does not apply to laser or plasma arc equipment.

This standard does not apply to light curing machines used in dental laboratories for indirect restorations, veneers, dentures and other oral products. this The relevant provisions of the standard are prioritized over the requirements of GB 9706.1.
