5960-66-011-0629 5960660110629 660110629 is an inclosure, including two or more electrodes, in which a flow of electrons may occur through a vacuum or a contained gas. the electronic conduction takes place either by means of electrons emitted from a cathode or by ionization of the contained gas. includes phototubes (photoemissive type only), geiger-mueller tubes, traveling wave tubes, cathode ray tubes and microwave tubes (klystron, magnetron, or the like). excludes items whose primary purpose is to produce light energy. also excludes photoelectric cell; and semiconductor device (as modified).

5310-01-011-0629 5310010110629 010110629 is a washer having a centrally located hole with a solid or laminated cross-section and two flat parallel bearing surfaces. the hole must be 75 percent or less than the largest dimension and the bearing surface finish is greater than 32 microinch (0.8 micrometer). the thickness cannot exceed 25 percent of the largest outside dimension. when the largest outside dimension is less than 1/4 inch or 6mm, the thickness must be 0.006 inches (0.15mm) or greater and for items 1/4 inch (6mm) or larger, the thickness must be 0.016 inches (0.4mm) or greater. the maximum tolerance is applied to dimensions and used as a determining factor. items with separable lamination use shim. for items fabricated from ceramic or electrically rated materials by specification or industry standards use insulator (1), washer. excludes disk, valve, graphite impregnated and lubricated items.
