This standard specifies the size, surface and mechanical properties of normal-walled, thin-walled and ultra-thin-walled tubes from 0.6mm to 2.1mm in metric specifications. This standard applies to the manufacture of needle tubes for intradermal, subcutaneous and intramuscular injection needles for human use and rigid straight stainless steel needle tubes for other medical devices (hereinafter referred to as needle tubes). This standard does not apply to pliable stainless steel syringes because their mechanical properties are different from the rigid straight stainless steel syringes specified in this standard. However, manufacturers of flexible needle tubes are encouraged to choose the dimensions specified in this standard.
