SIST EN 60998-2-1:2005

Overview

EN 60998-2-1:2004 (CLC adoption of IEC 60998-2-1:2002) defines particular requirements for connecting devices as separate entities with screw-type clamping units intended for low-voltage circuits for household and similar purposes. It is a supplement to EN 60998-1:2004 and supersedes earlier editions (including EN 685-2-2 (1983) and EN 60998-2-1:1993). The publication has the status of a group safety publication in accordance with IEC Guide 104 and was prepared and approved through CENELEC/CLC processes.

Key Topics and Requirements

This Part 2-1 focuses on the unique characteristics and tests applicable to screw-type clamping connecting devices. Key technical topics covered include:

• Scope and application: Devices as separate entities, primarily for connecting unprepared conductors in household and similar low-voltage circuits.
• Relationship to Part 1: Supplements and modifies EN 60998-1; where not mentioned, Part 1 provisions apply as reasonable. Additions/modifications are identified and additional subclauses are numbered from 101 upwards.
• Mechanical and electrical performance: Requirements and test specifications for secure clamping, mechanical robustness and electrical continuity (presented as requirements and italicized test specs).
• Clamping unit specifics: Criteria for screw-type clamps designed for unprepared conductors, including safe contact, retention, and prevention of conductor damage.
• Testing and verification: Test procedures for verifying compliance (temperature rise, mechanical endurance, dielectric and insulation characteristics are typical topics covered in this family of standards).
• Documentation, marking and conformity: Expectations for product identification, instructions and conformity with national implementation rules.
• Normative structure: Additional annexes (lettered AA, BB, etc.) and specific common modifications approved by CENELEC.

Practical Applications and Users

EN 60998-2-1 is intended for:

• Manufacturers of terminal blocks, screw-type connectors and wiring accessories who need to design and certify products for household low-voltage use.
• Product designers and R&D teams specifying clamping performance and safety features for consumer appliances, lighting and building installations.
• Test laboratories and conformity assessors performing type and routine testing per EN/IEC requirements.
• Regulatory and compliance professionals, procurement/specifiers and installers who require standardized safety, performance and interchangeability criteria.
