Full title and description

STB DD ENV 50204-1996 (2000) — National adoption (STB) of the CENELEC experimental standard DD ENV 50204:1995/1996 titled "Radiated electromagnetic field from digital radio telephones — Immunity test". The document specifies an EMC immunity test method for equipment exposed to radiated fields produced by digital radio telephones (notably GSM and DECT systems) using TDMA techniques.

Abstract

This standard defines a test procedure and reference parameters to evaluate the immunity of electrical and electronic equipment to radiated radio‑frequency electromagnetic fields generated by digital radio telephones operating around 900 MHz and 1.89 GHz (GSM and DECT). It was published as an ENV (experimental) document to give a common test reference for manufacturers and test laboratories prior to formal EN adoption.

General information

• Status: Withdrawn / inactive as an ENV; national STB version listed with adoption year 2000.
• Publication date: Original ENV first issued in 1995 (commonly referenced in national publications as 1995–1996); STB adoption indicated as 2000 in national catalogue records.
• Publisher: Originally issued by CENELEC (as ENV 50204); national publication/adoption under the STB designation for the country that adopted the ENV text.
• ICS / categories: Electromagnetic compatibility and telecommunications / EMC testing (commonly catalogued under ICS codes for EMC and telecommunications, e.g., 33.*).
• Edition / version: DD ENV 50204:1996 (the DD/ENV experimental version) — national STB identification adds the adoption year notation "(2000)".
• Number of pages: Small technical report — national and vendor listings show approximately 12–14 pages depending on the national print; many catalogues list 12–14 pages.

Scope

The scope covers a practical immunity test method for assessing how electrical and electronic apparatus perform when exposed to pulsed and modulated radiated fields from digital radio telephones — specifically GSM (around 900 MHz) and DECT (around 1.89 GHz) using TDMA. The standard sets test frequencies, modulation types, field levels and general test‑area/uniformity recommendations so that results from different laboratories are comparable.

Key topics and requirements

• Definition of test signal types and modulation (TDMA characteristics typical for GSM/DECT at the time).
• Specified frequency bands of concern (circa 900 MHz and 1.89 GHz) and associated test points.
• Field strength/test level specifications and performance criteria to judge pass/fail.
• Measurements and equipment setup: antenna, power calibration, measurement grid/uniform area and field sensing.
• Reference to related EMC test practice in the EN/IEC 61000‑4‑3 family and transition guidance where ENV provisions were incorporated into later EN amendments.

Typical use and users

Used by EMC test laboratories, product compliance engineers, and manufacturers of telecommunications, consumer and industrial electronic equipment for assessing susceptibility to radio telephony fields. It served as a practical interim method for product development and pre‑compliance testing before the EN/IEC radiated immunity norms were finalized.

Related standards

Closely related to and subsequently incorporated into the EN/IEC 61000‑4‑3 radiated RF immunity series; ENV 50204 provisions informed amendments to EN 61000‑4‑3 (late 1990s). Other related ENVs/standards in the EMC test family (ENV 50140 and EN/IEC 61000‑4‑2/4‑6 etc.) are also relevant for full EMC test programmes.

FAQ

Q: What is this standard?

A: An experimental European EMC test document (ENV) titled "Radiated electromagnetic field from digital radio telephones — Immunity test" that was issued by CENELEC as ENV 50204 and subsequently listed/adopted in several national catalogues (the STB entry denotes a national adoption labeled STB DD ENV 50204-1996 with a 2000 adoption notation).

Q: What does it cover?

A: A test method to assess immunity of electronic apparatus to radiated RF fields produced by GSM and DECT digital radio telephones (TDMA signalling), including frequency/test point selection, modulation characteristics, field levels, and basic measurement setup requirements.

Q: Who typically uses it?

A: EMC laboratories, compliance engineers, product designers and manufacturers performing immunity testing or pre‑compliance checks against radiated radio‑telephony fields.

Q: Is it current or superseded?

A: ENV 50204 was an experimental pre‑standard and has been withdrawn as a standalone ENV; its technical content was folded into the EN/IEC 61000‑4‑3 radiated immunity standard and its amendments during the late 1990s, so users should apply the current edition of EN/IEC 61000‑4‑3 and relevant national adoptions for formal compliance.

Q: Is it part of a series?

A: Yes — it belongs to the family of EMC test recommendations and EN/ENV documents addressing immunity (the ENV/EN 50xxx and EN/IEC 61000‑4‑x series). ENV documents are experimental/interim texts intended to be replaced by formal ENs or EN/IEC harmonized documents.

Q: What are the key keywords?

A: EMI/EMC, radiated immunity, GSM, DECT, TDMA, ENV 50204, DD ENV 50204, STB adoption, EN 61000‑4‑3.
