K21045 SCP08 Certification of Glass Bulb Activators for SBC Fire Suppression Systems

Aerosol- and nitrogen-based fire suppression generators are typically activated through certified fire detection systems that comply with EN 54 standards, in combination with extinguishing control and indicating equipment in accordance with EN 12094-1. For small-scale or localized applications where only a single generator is used, a reliable and certified alternative is available: glass bulb temperature sensors. These sensors, which are well known from sprinkler technology, provide an effective and direct activation method in the event of a temperature rise.

The specific certification scheme, "K21045 SCP08 Glass Bulb Activators for Solid Bound Compound (SBC) Generators", defines the technical and performance requirements for this activation method, based on proven glass bulb technology used in sprinkler systems.

When a certified glass bulb ruptures at a predetermined temperature, it mechanically releases a spring-loaded mechanism that frees a metal pin. This pin subsequently activates the fire suppression generator. Based on the Specific Certification Program SCP08, the complete activation mechanism can be tested and certified. The program also establishes the maximum permissible dimensions and application limits of this activation method, ensuring sufficiently rapid generator activation, which is essential for effective fire suppression.

Scope

The certification program ‘SCP08 Glass Bulb Activators for Solid Bound Compound (SBC) Generators’ describes the test methods and requirements for glass bulb activators and their housings when used in combination with SBC generators. The program specifies clear functional and performance criteria for glass bulb technology specifically applied to object protection using SBC generators. This activation principle may only be used in controlled chloride environments.

Certification Criteria for Glass Bulb Activators According to SCP08

Glass bulb activators used in combination with SBC fire suppression generators must comply with stringent requirements derived from relevant standards, including EN 15276-1, EN 12259-1, and EN 54-7.

The housing of these activators must be manufactured from stainless steel (AISI 304 or AISI 316) and be suitable for controlled indoor environments. During a standardized fire test, activation must occur within two minutes to meet the required performance criteria.

Further information regarding the technical requirements and test procedures can be found in Chapter 5 of the Specific Certification Program ‘SCP08 Glass Bulb Activators for Solid Bound Compound (SBC) Generators’.

K21045 SCP03 – The Certification Programme for Fire Safety in Marine Engine Rooms

Fires in marine engine rooms pose a significant risk to crew, vessel, and cargo. To ensure safety at sea, ships must comply with strict fire‑protection regulations. Many vessels are equipped with advanced fire‑suppression systems, but their effectiveness must be demonstrated. To support this need, Kiwa has developed the specific certification programme SCP03 – Extinguishing of Large-Scale Fires, Extinguishing of Large Fuel and Operational Fires in Maritime Applications.
