Magnetic tape sound recording and reproducing systems. Part 5: Electrical magnetic tape properties
Applies to non-perforated magnetic tape used for professional and domestic analogue sound recording and reproduction. Lists and defines the characteristics, methods of measurement and equipment necessary to determine the electrical properties of magnetic tapes. Will also enable users of magnetic tapes to compare the technical product data of different manufacturers, produced in accordance with…
Defines local area networks and their characteristics. Gives an overall view of the characteristics to be taken into consideration in all standardization work on local area networks. This publication has the status of a technical report. Note: -For the price of this publication, please consult the ISO/IEC price-code list.
Applies to the reversible process achieved by the PCM encoder/decoder system that transforms two audio signals into one PCM signal for compatibility, with either 525 line/ 60 field or 625 line/50 field television system. Establishes the signal format for the PCM encoder decoder for reproducing audio signals in PCM form on a consumer video cassette system. Ensures standardized system operation…

Seamless Zirconium Alloy Tubing for Reactivity Control Rods
Covers the requirements for the fabrication and properties of
seamless zirconium alloy tubing to be used in reactivity control
rods. Generally, this Standard applies to tubing with a diameter
to wall thickness ratio of less than 80:1.
Covers a series of requirements for nondestructive examinations
performed at various stages of manufacture of zirconium alloy
components as detailed in this series of Standards. The
requirements cover nondestructive examinations by visual,
radiographic, liquid-penetrant, and ultrasonic techniques. The
requirements detail applicability, requirements of the
inspection, and accpetance…
Provides the physical and mechanical property data to be used for
design purposes for the zirconium alloy components defined in
this series of Standards.
Manually Operated Shut-Off Valves for Gas Piping Systems
1.1 Scope
1.1.1 This standard applies to newly produced manually operated shut-off valves for gas piping systems and constructed of entir ely new, unused parts and materials which: (a) are intended for use downstream of the distributors meter or regulator, for operation at a maximum pressure of 1/2 psig (3.4 kPa), (b) are capable of operation at ambient temperatures between 32°F (0°C) and…
