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.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard was drafted. Shenyang Institute of refractory metals, Zhejiang Metallurgical Research Institute Limited.
The main drafters of this standard. Zhou Ming, Mediate Zhengxin Wen, Xiao Kai, Dong Zhaohui, Yonggang, pore water dragon, Li Feng.
This standard replaces the standards previously issued as follows.
--- GB/T 8893-1988, GB/T 8894-1988, GB/T 8894-2007.
