Information technology — Programming languages — PL/1 general purpose subset
The language defined is different from those of previous PL/I standards, although substantially upward compatible, at the source program and semantic level. The differences are summarized in appendix A. Specifies the syntax and semantics of conforming PL/I programs. Defines a conforming processor (or conforming implementation) only in terms of those conforming programs. The definition is…

Road vehicles — Generation of standard EM field for calibration of power density meters from 20 kHz ...
Applies to power density meters used (by the Department of Defense) in measuring high intensity (hazard level) RF fields. The techniques described are based on: parallel plate and parallel wire transmission lines, transverse electromagnetic mode transmission cells, various directive antennas and open ended waveguide. Major emphasis is on the TEM cells.
Textile floor coverings — Non-destructive measurement of pile thickness above the backing — WRONZ ga...
The method is based on determination by measuring the distance between the planes of the pile surface located under a standard pressure and the plane of the backing surface located under a standard loading. This method and that of ISO 1766 may not give identical results. In case of dispute or where maximum accuracy is required, thickness shall be determined by the method of ISO 1766.
