Full title and description
GOST 6479-73 — State Standard of the USSR. Electromagnetic compatibility: Methods for determining the sensitivity (susceptibility) of radio receiving equipment to pulse interference. The standard specifies test methods, test signal parameters and procedure to assess the performance degradation of radio receivers when exposed to impulse-type electromagnetic disturbances.
Abstract
This standard defines laboratory procedures and pulse signal characteristics used to evaluate the susceptibility of radio receiving equipment to pulse (impulse) electromagnetic interference. It establishes types of test pulses, amplitude and waveform parameters, coupling methods, and criteria for classifying degraded performance or failure. The standard is intended to provide reproducible, comparable test results for equipment used in communications and radio-electronic systems.
General information
- Status: National standard (GOST) originally issued in the USSR; referenced historically for EMC testing. May be superseded or withdrawn and in practice often supplemented by later regional or international EMC standards.
- Publication date: 1973
- Publisher: USSR State Committee for Standards (Gosstandart of the USSR)
- ICS / categories: 33.020 Electromagnetic compatibility (EMC) of technical equipment; 33.100 Radio engineering
- Edition / version: Original issue — 1973 (designation: GOST 6479-73)
- Number of pages: Typically a short standard (commonly under 20 pages); exact page count varies by publication format (estimate: 6–16 pages)
Scope
GOST 6479-73 covers methods for generating and applying impulse-type electromagnetic disturbances to radio receivers to determine their sensitivity (susceptibility) to such pulses. It addresses definitions of test pulses, the shape and duration of impulses, permissible levels, coupling methods into antenna inputs and auxiliary circuits, measurement procedures, and criteria for judging receiver performance under test. The standard is focused on bench and laboratory testing rather than installation or field immunity measures.
Key topics and requirements
- Definitions and classification of pulse (impulse) disturbances relevant to radio receivers.
- Parameters of test pulses: waveform shape (for example, damped oscillatory or unipolar pulses), rise time, duration, repetition rate and amplitude.
- Methods for coupling pulses into receiving equipment (antenna terminals, power supply and control circuits) to simulate realistic interference paths.
- Instrumentation and setup: pulse generators, coupling networks, loads and measurement equipment required to perform tests.
- Test procedures: sequence of tests, applied levels, observation of receiver functions and performance measurements during and after pulse exposure.
- Performance criteria and pass/fail conditions: allowable degradation in sensitivity, spurious responses, desensitization, blocking and transient overload limits.
- Reporting requirements: test conditions, measured pulse parameters, recorded receiver behavior and conclusions about susceptibility.
Typical use and users
This standard is used by test laboratories, manufacturers of radio receivers and other radio-electronic equipment, quality assurance and compliance engineers, and designers concerned with electromagnetic compatibility and immunity. It is applied when assessing how receivers respond to transient pulse interference—useful for military, industrial, and civil radio communications equipment development and acceptance testing.
Related standards
GOST 6479-73 is part of a family of EMC and radio-receiving standards from the Soviet era. Related documents include other GOSTs and OSTs on electromagnetic compatibility, immunity test methods (for example, for continuous-wave interference, conducted and radiated susceptibility), and later national and international standards that supersede or expand on pulse-immunity testing (for example, IEC and CISPR series documents related to EMC and IEC impulse test methods). National standards for surge and impulse testing may also be relevant.
