STANDARD SPECIFICATION FOR STAINLESS STEEL NEEDLE TUBING

1. Scope 



1.1 This specification covers austenitic, stainless steel needle tubing in gard-drawn tempers for industrial applications. 

1.2 In general, needle tubing describes small-diameter tubing with outside diameters(ODs)in the range of 0.008 to 0.203 in. (0.2 to 5.2mm) with nominal wall thicknesses in the range of 0.002 to 0.015 in. (0.05 to 0.4mm). needle tubing gages are normally 6 through 33. 

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parethese are for information only.
