Full title and description

STB BS ISO 8528-12:2022 — Reciprocating internal combustion engine driven alternating current generating sets — Part 12: Emergency power supply to safety services. This part of ISO 8528 specifies special requirements for the performance, design and maintenance of engine-driven AC generating sets intended to supply emergency power to safety services (for example in hospitals, high-rise buildings and other places where continuity of safety-related electrical supplies is required).

Abstract

This standard applies to reciprocating internal combustion engine driven AC generating sets used specifically for emergency power supply to safety services. It provides classification, criteria for determining required power, operating limits and additional requirements (batteries and starters, fuel capacity, ventilation, robustness, electrical protection, controlgear and switchgear) and takes into account provisions given in ISO 8528-1 to ISO 8528-6 and ISO 8528-10.

Scope

Specifies requirements and guidance for engine-driven AC generating sets when they are intended to provide emergency power to safety services. The standard covers classification, calculation of required power and operating limits, mechanical and electrical provisions (including batteries, starters, fuel capacity and ventilation), robustness and vibration considerations, and requirements for controlgear, protection, measurement, monitoring and maintenance for these specialized emergency applications. It is intended to be used alongside the general parts of ISO 8528.

Key topics and requirements

• Classification and designation of generating sets for emergency power to safety services.
• Criteria and procedures for determining the required power for safety-service loads.
• Operating limit values and duty-cycle considerations for emergency applications.
• Requirements for battery and battery-charger systems, and for alternative starting systems (e.g., compressed-air starters).
• Minimum fuel capacity and fuel system considerations for guaranteed emergency runtime.
• Ventilation and cooling provisions, including ventilation louvres and installation considerations.
• Mechanical robustness against vibration and environmental stresses.
• Controlgear and switchgear requirements: protection, measurement, monitoring and control for the AC generator and safety circuits.
• Maintenance, inspection and documentation recommendations specific to emergency power installations.

Typical use and users

Intended for manufacturers of generating sets, system designers and integrators, electrical and mechanical engineers, facilities and maintenance teams in hospitals, high-rise buildings, public assembly venues and other installations requiring reliable emergency power for safety services. Also used by standards committees, testing laboratories and regulators when specifying or assessing emergency power systems.
