14、Procurement-Maintenance Engi- neering Division, Signal Corps Engineering Laboratories, and cover various items of signal equipments which are sub- ject to rep8ir, test and inspectione These repair stand- ards are documents which set forth the specific repair re- quirements and test standards to be a

15、pplied to the individ- ual equipments being repaired and tested. Signal Corps Repair Standards are prepared for the specific use of the fifth echelon Signal Repair Shops in repairing and determining the quality and acceptability of repaired signal equipments covered by these standards. The use of Si

16、gnal Corps Repair Stand8rds is recommended as a guide and reference for any 8gency having occnsion to repair, test or inspect an item of signal equipment for which a repair standard has been prepared. Signal Corps Rep&ir Standard No. REP-lOOl is a general standard and is subsidiary to any individual
