Separately produced test coupons representing fittings may be used. 3 shall be met. 3 Coupons From Separately Produced Test Forgings. 3(a) through (e). (a) The separate test forging shall be of the same heat of material and shall be subjected to substantially the same reduction and working as the production forging it represents. (b) The separate test forging shall be heat treated in the same furnace charge and under the same conditions as the production forging. (c) The separate test forging shall be of the same nominal thickness as the production forging.
B) Secondary Members. Secondary members are defined as those members typically used as bracing to maintain primary member system geometry, and which under all loading conditions, are not designed to sustain any significant stress. Significant stress is defined as being in excess of 50% of the allowable stress permitted by NF-3000. --``,````,,,,````,`,`,```,`,``,,-`-`,,`,,`,`,,`--- Copyright ASME International Provided by IHS under license with ASME No reproduction or networking permitted without license from IHS NF-1231 WELDING BETWEEN TYPES OF SUPPORTS Welded Joints Between Plate and Shell Type and Linear Type Supports Welded joints between Plate and Shell Type Supports (NF-1212), and Linear Type Supports (NF-1213) shall meet the rules of either Plate and Shell Type or Linear Type welded joints of this Subsection.
