Anotace textu normy ASTM B687-99(2023) :
This specification establishes the requirements for brass and copper pipe nipples within a specified size range. Chromium-plated pipe nipples covered by this specification are intended for use in the interior of decorative appliances. Both brass and copper pipe nipples should be produced from regular or extra strong pipes while chromium-plated pipe nipples are produced from regular weight brass pipes. All pipe nipples should be threaded in both ends with NPT Taper Pipe Threads except for close nipples with lengths shorter than the specified value. Threads should be right hand on both ends except when otherwise specified. Chromium plated nipples use short plumbing (hospital) threads. Pipe nipple ends shall be cut reasonable square to the central axis and chamfered on the outside with all outside burrs removed.
