2、ulated by the Electron Tube Council of the Joint Electron Device Engineering Councils. EIA engineering standards are designed to serve the public interest through eliminating mis- understandings between manufacturers and purchasers, facilitating interchangeability and improve- ment of products, and
3、assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such standards shall not in any respect preclude any member or non-member of EIA from manufacturing or selling products not conforming to such standards. Recommended standar

Where a gun U designed specifically for either selective erasure or nonstore writing, use “r” or “n”, respectively, in place of “w” for writing or 7 for flooding. 3. Any mesh or mesh-like structure lying in a plane perpendicular to the axi
