Scope

GB/T 8894-2014 is the English-translated version of 铜及铜合金波导管.

GB/T 8894-2014 is the Chinese national specification for copper and copper alloy waveguide tube. It fixes the alloy grades, tempers and dimensions of circular, rectangular, square and flat rectangular waveguide, together with the test methods, inspection rules, marking, packaging, transport, storage, quality certificate and contract content.

Clause 3 defines eccentricity as half the difference between the largest and the smallest wall thickness in a cross-section perpendicular to the tube axis.

Compared with the 2007 edition it adds the TU00, TU0 and BMn40-1.5 grades, the rectangular models R900, R740 and R620, the flat rectangular model M12 and a stress-relieved HR50 state, and renames verticality as squareness.

It serves makers of radio and telecommunications equipment. It replaces GB/T 8894-2007, was issued on 24 July 2014 and has applied since 1 February 2015.

Foreword

This standard is in accordance with GB/T 1.1-2009 given rules drafted.

This standard replaces GB/T 8894-2007 "copper and copper alloy waveguide." This standard compared with GB/T 8894-2007, mainly like Under changes.

--- Increased TU00, TU0, BMn40-1.5 three alloy grades and the corresponding technical requirements;

--- Rectangular waveguide increases R900, R740, R620 three models and the appropriate technical requirements;

--- Flat rectangular waveguides increases the model M12, and an increase in the corresponding technical requirements;

--- Models R120, R100, R84, R70, R58, R48 rectangular waveguide bore fillet radius r1 revised to 0.6 from 0.8;

--- Rectangular waveguide bore size tolerances canceled II grade;

--- Model R32 increased wall thickness specifications, increasing the wall thickness from the original specifications 3.00,4.00,5.00,6.00 2.030 and the corresponding technical requirements;

--- Tubing "eccentricity", technical specifications redefined, accuracy is improved;

--- The pipe length to allow deviation and re-cut the slope provides accuracy is improved;

--- The "verticality" to "squareness";

--- Add "pull aside stress relief (HR50)" status.

1 Scope
