Scope

This Standard specifies the dimensions, surface and mechanical properties of
normal and thin-walled tubing of designated metric sizes 0.3 mm to 3.4 mm,
and of extra-thin-walled tubing of designated metric sizes 0.6 mm to 2.1 mm.
This Standard applies to rigid stainless-steel needle tubing suitable for use in
the manufacture of intradermal, hypodermic, intramuscular injection needles
and other medical devices primarily for human use (hereinafter referred to as
tubing).
This Standard does not apply to flexible stainless-steel tubing because the
mechanical properties differ from those specified for rigid tubing in this Standard.
However, manufacturers and purchasers of flexible tubing are encouraged to
adopt the dimensional specifications given in this Standard.

Summary	This Chinese standard specifies the metric sizes 0. 3mm to 3. 4mm normal wall, 0. 6mm to 2. 1mm thin and ultra-thin wall tube size, surface and mechanical properties. This standard applies to the manufacture of human intradermal, subcutaneous, intramuscular needle needles and other medical equipment with a hard straight stainless steel needle. This standard does not apply pliable stainless steel needle tube, because of its mechanical properties different from those specified in this standard hard straight stainless steel needle. But encouraging Yi curved needle tube manufacturer and the purchaser choose the provisions of this standard size.
