The dental needle neck strength tester is mainly used to evaluate the neck bending strength, torsional performance, and fatigue life of dental rotating instruments (such as needles, drills), and is in compliance withYY0302-1998TheYY/T0874-2013Waiting for standards.

Testing standards and instruments

Dental Needle Neck StrengthTesting should followYY 0302.1-2010The Needle Dental Rotating Instruments1part:Steel and Hard Alloy Needle ",YY 0302.2-2016The methods and requirements for testing the neck strength of dental needles in the standards.YY 0302.1-2010The requirements for neck strength in China are as follows:

The needle must not break,Or the deformation should not exceed:

---Steel car needle:0.08mm;

--Hard alloy car needle:0.05mm.

The test should be conducted after the corrosion testYY 0302.1-2010In the standard6.4Requirement to proceed.
