Scope

This standard specifies the size, surface and mechanical properties of the tube
having normal wall and thin wall of nominal specification 0.2 mm ~ 3.4 mm AND

This standard applies to the rigid straight stainless-steel needle tubing used for
human body skin, subcutaneous, muscle and vein injection (hereinafter referred
to as the needle tubing).
This standard does not apply to easy-to-bend stainless-steel needle tubing,
because its mechanical properties are different from the rigid stainless-steel
needle tube as specified in this standard; however, it is recommended for the
manufacturer and purchaser of the easy-to-bend stainless-steel needle tubing
to select the sizes as specified in this standard.
