Specifying BlazeMaster CPVC is no different; getting it right the first time is something we take seriously.

If you want to explore the possibilities of specifying BlazeMaster CPVC, if you are looking for more detailed insight into the effects of BlazeMaster CPVC on your next new build or retrofit, or of you just want to get your next project underway quickly, The Orange Book is the place to start.

The Orange Book is easier than ever to explore. Our online edition gets you and your team fast access to the regulations, standards and product details you need. Meanwhile, ​​our new online specification generator will instantly give you access to the requirements you need to design an efficient and compliant BlazeMaster sprinkler system.

Below are some of the more frequently asked questions about specifying CPVC for fire protection; here’s how The Orange Book can help.

Are Sprinklers a Legal Requirement?

Government legislation as of November 2020 includes mandatory provision of fire sprinklers in buildings with a top floor height of 11 metres above ground level, including high-rise residential buildings. The threshold requirement was reduced from 30 metres. In 2021, BS 9251 (code of practice for fire sprinkler systems for domestic and residential occupancies) underwent major regulatory changes. 

It is important to have access to up to date codes of practice and building regulations; the Orange Book contains BS 9251 guidance for designers and specifiers, BS EN 12845 hazard information and the latest LPCB guidance. 

How Often should CPVC Sprinkler Systems be Tested?

After a BlazeMaster fire protection system is installed and any solvent-welded joints have cured, the system should be hydrostatically tested, as per the requirements of BS EN 12845. 

Any further maintenance should be carried out in accordance with the Standard for Inspection, Testing and Maintenance of Water Based Extinguishing Systems as defined by the applicable standard.

As for the CPVC products themselves, BlazeMaster pipes and fittings are third party approved by FM Global, and appear in the FM Approval Guide, which includes engineering data and technical information on the application and use of listed products.

For more information on testing to applicable standards, consult the System Specification section of The Orange Book.

Can CPVC Sprinkler Pipe be Exposed?

BlazeMaster CPVC sprinkler pipe is approved for installation in areas where ambient temperatures are within the range of 2°C to 65°C (35°F to 150°F). 

Piping systems must be laid out to ensure the piping is not closely exposed to devices that generate heat in excess of 65°C (150°F) such as light fixtures and steam lines.

If the installation is in an area subject to freezing temperatures, the sprinkler system must be protected from freezing. A frozen system will not only be deactivated, but the pressures that may build up can cause the sprinkler heads to open or damage the pipes.

The Orange Book contains detailed guidance on product ratings, capabilities and material properties. Consult the Technical Performance and Standards section for more information.

How Environmentally Friendly is CPVC Pipe?

All Lubrizol products undergo Life Cycle Assessments to determine their environmental impact during procurement, manufacturing, distribution and consumption.

BlazeMaster CPVC keeps piping systems ready for emergencies by preventing scaling and corrosion for the life of the system. It also provides natural immunity to microbiologically influenced corrosion. Its C-factor of 150 remains consistent in its hydraulic capability, compared to steel which has a starting C-factor of 120 and decreases over time.
