What is PD IEC/TR 63054‒ Fire risk analysis and risk reduction about?
PD IEC/TR 63054 is an international standard that covers guidelines for the safety of low-voltage switchgear and controlgear.
PD IEC/TR 63054 specifies the requirements for the fire risk analysis and risk reduction measures like terms, ignition modes for electrical fires, overheating at the connection point due to loose connections, overheating of internal power conductors, arcs, failure of electronic components and concludes the condition, for the safety of low-voltage switchgear and controlgear.
PD IEC/TR 63054 applies to the fire risk analysis of low-voltage switchgear and controlgear (equipment) referring to the IEC 60947 standards, where the following applies:
- Only the case where the fire originates (typically under fault or misuse conditions) within the equipment
- Only to the equipment installed in normal environments. Hazardous environments like the presence of combustible material are not considered
- Only the case of products selected, installed, and used according to the manufacturer’s instructions and installation rules
Note: PD IEC/TR 63054 does not consider the following cases:
- Faults addressed by IEC TR 61641
- Risks due to smoke emissions
- Double faults, i.e., multiple phenomena, potentially combined
Who is PD IEC/TR 63054‒ Fire risk analysis and risk reduction for?
PD IEC/TR 63054 on fire risk analysis and risk reduction is useful for:
- Manufacturers and suppliers of low-voltage switchgear and controlgear
- Dealers and distributors of low-voltage switchgear and controlgear
- Designers of low-voltage switchgear and controlgear
- Test/ service providers for low-voltage switchgear and controlgear
Why should you use PD IEC/TR 63054‒ Fire risk analysis and risk reduction?
As fire-ignition hazards are inherent with electricity, the installation rules and product standards for electrical equipment, are determined to provide risk reduction measures and to minimize residual risk without compromising product safety and function.
PD IEC/TR 63054 describes to you, the fire risk analysis of electrical equipment and risk reduction measures, in IEC 60947 relevant publications. It provides you with the information that the other product committees may also find useful, while intended to apply specifically to low voltage switchgear and controlgear.
PD IEC/TR 63054 reviews and discusses the fire hazards, namely the flame ignition mechanisms, relevant for low-voltage switchgear and controlgear. It includes the related risk reduction measures that are subsequently reported for each of those mechanisms.
PD IEC/TR 63054 gives the measures based on a system approach, which are not limited to construction materials requirements. It includes the design rules and type testing, to ensure that the equipment does not cause fires in normal operation or due to reasonably foreseeable faulty conditions.
