DEFINITIONS For the purpose of this standard, the abbreviations, symbols, and definitions are specified in appendices A and B of MIL-PRF-1. 4. GENERAL REQUIREMENTS 4.1 Numbering system. The test methods are designated by numbers assigned in accordance with the following system.
4.1.1 Category of tests. Each test method is designated by a four-digit number, with significance, assigned in accordance with the following criteria: a. Category of tubes Numerical series (first digit) General (tests applicable to more than one tube category) .................................. 1000 to 1999 Receiving, transmitting, and power ...................................................................... 2000 to 2999 Cold cathode, corona and glow discharge voltage regulators, graphic indicator, ignitron pulse modulators, and thyratrons ...............................
3000 to 3999 Crossed field, gas switching, klystrons, magnetrons, M-backward wave, O-type backward wave, and traveling-wave tubes ................................... 4000 to 4999 Cathode ray, cathode-ray charge storage, phototubes, image orthicons, and vidicons ...................................................................................................... 5000 to 5999 Radiation counter ................................................................................................ 6000 to 6999 b. Within the above series, numbers will be assigned as follows:
Category of tests Last three digits of series Environmental/Mechanical (physical) ................................................................... 001 to 199 Electrical .............................................................................................................. 200 to 499 Life .................................................................................................................. 500 to 699 4.1.2 Revisions. Revisions to test methods will be indicated by a capital letter following the method number. For example, the first revision of method 1001 will be 1001A. Letters I and O will not be used. 2
