SIST ETS 300 340:1998/A1:1998

SIST ETS 300 340:1998/A1:1998 is the Slovene adoption of ETS 300 340/A1 Edition 1, published by SIST. It specifies EMC requirements for European Radio Message System (ERMES) paging receivers and ancillary equipment, and it is intended to support harmonized EMC conformity work under Council Directive 89/336/EEC.

What does SIST ETS 300 340:1998/A1:1998 specify?

SIST ETS 300 340:1998/A1:1998 covers the electromagnetic compatibility requirements for ERMES paging receivers and their ancillary equipment. The amendment is part of the move to make ETS 300 340 a Harmonized EMC Standard.

The amendment changes the foreword and adds a normative annex that links the standard’s EMC subclauses to the essential requirements of the Directive. In practice, that makes it easier to see which test areas matter for compliance evidence.

What are the key requirements of SIST ETS 300 340:1998/A1:1998?

SIST ETS 300 340:1998/A1:1998 is mostly about identifying which EMC tests and clauses are relevant for Directive compliance. The amendment does not add product design rules of its own so much as it ties the base standard to the harmonized EMC framework.

• Annex A lists the subclauses relevant to the essential requirements of Council Directive 89/336/EEC. For a compliance file, this is the main map from the standard to the legal EMC obligations.
• Clause 8.2, 8.3 and 8.4 cover disturbance at the enclosure, DC power input/output ports, and AC mains power input/output ports. For manufacturers, these are the points where emissions from the equipment and its ancillary equipment are assessed.
• Clause 9.2 covers RF electromagnetic field immunity in the 80 MHz to 1 000 MHz range. This matters because the receiver has to keep working in real radio-frequency environments.
• Clause 9.3 to 9.5 cover electrostatic discharge, fast transients common mode, and RF common mode current clamp injection from 0,15 MHz to 80 MHz. These are the kinds of disturbances that often appear on enclosures and connected cables during testing.
• Clause 9.6 to 9.8 cover transients and surges in the vehicular environment, voltage dips and interruptions, and surges in common and differential mode. In practice, these clauses help teams check whether the receiver and connected equipment remain stable under power-line and vehicle-supply disturbances.
• The foreword says ETSI prepared the amendment in response to European Commission mandate BC-T-353. That tells users the document is meant for regulatory alignment, not only internal technical use.
• The foreword also states that the ETS is based on EN 50081-1, EN 50082-1 and other standards where appropriate. In practice, test labs often use that as the starting point when planning EMC evaluations.

What terms does SIST ETS 300 340:1998/A1:1998 define?

• ElectroMagnetic Compatibility (EMC) - The ability of equipment to operate without creating or suffering unacceptable electromagnetic disturbance.
• European Radio Message System (ERMES) - The paging system covered by this standard.
• Radio Equipment and Systems (RES) - The ETSI technical committee named in the foreword as the body that prepared the amendment.
• European Telecommunications Standards Institute (ETSI) - The standards organization that published the base ETS and this amendment.
• European Telecommunication Standard (ETS) - The document type used for the base standard being amended here.
• Harmonized EMC Standard - A standard intended to be referenced in the Official Journal of the European Communities for the EMC Directive.

Who uses SIST ETS 300 340:1998/A1:1998?

SIST ETS 300 340:1998/A1:1998 is used by people who design, test, approve, or buy ERMES paging equipment.

• Manufacturers and design engineers use it to understand which EMC stress and disturbance areas apply to the receiver and its ancillary equipment.
• EMC test laboratories use it to select the disturbance and immunity checks named in clause 8 and clause 9.
• Compliance and quality teams use Annex A when building evidence for Directive-related conformity work.
• Buyers and technical specifiers use it when they need an EMC standard to cite for ERMES paging receivers.

What changed in SIST ETS 300 340:1998/A1:1998 from the previous edition?

This amendment modifies ETS 300 340 (1994). The changes stated in the amendment are:

• the foreword is replaced with text linking the standard to EC mandate BC-T-353 and Council Directive 89/336/EEC;
• a normative Annex A is inserted;
• Annex A identifies the subclauses relevant to compliance with the essential requirements of the Directive;
• the foreword now states that the ETS is based on EN 50081-1, EN 50082-1 and other standards where appropriate.

Which standards are used with SIST ETS 300 340:1998/A1:1998?

The amendment names these companion references:

• ETS 300 340 (1994) - the base European Telecommunication Standard that this amendment modifies.
• EN 50081-1 - one of the generic standards named as a basis for the ETS, contributing the emission side of the EMC framework.
• EN 50082-1 - one of the generic standards named as a basis for the ETS, contributing the immunity side of the EMC framework.
• Council Directive 89/336/EEC - the legal EMC framework to which Annex A maps the relevant subclauses.

What does the SIST ETS 300 340:1998/A1:1998 document contain?

The amendment mainly contains editorial and compliance-linking material rather than a full rewrite of the EMC tests. It replaces the foreword, adds Annex A, and provides a compliance mapping table.

Table A.1 is the key technical table. It cross-references disturbance and immunity subclauses to the relevant Directive articles, which is useful when preparing test plans, conformity documentation, and regulatory justification.

The document also includes transposition dates and a short history showing the first edition, the approval process, and Amendment 1.
