Straightness
As for the straightened molybdenum wire,The following requirements of straightness shall be reached:
①As for the molybdenum wire at or thinner than100μm（16.33mg）,vertical height of 500mm freely suspended wire shall not be less than 450mm.
②As for the molybdenum wire thicker than 100μm,piece of200mm wire is put on a paper sheet and the arc is evaluated between two points separated by 100mm.the maximum height of the arc is 10mm.
