This part of IEC 61249 gives requirements for properties of modified brominated epoxide woven E-glass reinforced laminate sheets of defined flammability (vertical burning test), copper-clad in thicknesses of 0,05 mm up to 3,2 mm. The flammability rating is acheived through the use of brominated fire retardants reacted as part of the epoxide polymeric structure. The glass transition temperature is defined as being between 150 ℃ and 190 ℃. Some property requirements may have several classes of performance. The class desired needs to be specified on the purchase order, otherwise the default class of material may be supplied.

This part of IEC 60999 applies to screw-type and screwless-type clamping units for connecting devices, either as separate entities or as integral parts of equipment, for the connection of electrical copper conductors (complying with IEC 60228), rigid stranded and/or flexible, having a cross-section above 35 mm and up to and including 300 mm and equivalent AWG/kcmil sizes with a rated voltage not exceeding 1 000 V a.c. and a frequency up to and including 1 000 Hz and 1 500 V d.c. It applies to clamping units primarily suitable for connecting unprepared conductors. This standard does not apply to clamping units: - for connection by crimping or soldering; - for non-universal clamping units defined in 3.10.2 of IEC 60999-1.
