Sterile acupuncture needles for single use1 Scope This International Standard specifies the requirements for the sterile acupuncture needles for single use (specialized for filiform needles).

The MEMS structures often have higher fundamental resonant frequency and higher strength than macro structures

BS 25999-2 specifies requirements for establishing

MEMS resonators are small electromechanical structures that vibrate at high frequencies

This International Standard is a combined specification providing for classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal

In the case of use of other materials
