This section of IEC 60998 pertains to connecting devices that function as standalone units for the connection of two or more electrical copper conductors. These conductors, which must comply with IEC 60228 or IEC 60344, can be either rigid (solid or stranded) or flexible, with a cross-sectional area ranging from 0.2 mm² to 35 mm², including equivalent AWG sizes. The rated voltage for these connections must not exceed 1,000 V a.c. at frequencies up to 1,000 Hz, and 1,500 V d.c., specifically for applications involving electrical energy in households and similar settings.
NOTE: Connecting capacities below 0.5 mm² are subject to IEC 60344, while those equal to or greater than 0.5 mm² are governed by IEC 60228.
Connecting devices that necessitate special tools, apart from those designed for twist-on connections and insulation-piercing connections, do not conform to this standard.
This standard outlines the general requirements that should be applied alongside the relevant Part 2, which provides detailed specific requirements for:
- Devices with screw-type clamping units (IEC 60998-2-1);
- Devices with screwless-type clamping units (IEC 60998-2-2);
- Devices with insulation-piercing clamping units (IEC 60998-2-3);
- Devices with twist-on connections (IEC 60998-2-4);
- Devices with connecting boxes (junction and/or tapping) (IEC 60998-2-5).
