Help make occupancies safer by using the latest test method for determining fire performance characteristics of pipe insulation assemblies.

NFPA^® 274, Standard Test Method to Evaluate Fire Performance Characteristics of Pipe Insulation, is a vital resource to help testing laboratories and manufacturers ensure the selection of assemblies that contribute less heat, flame, and smoke in fire scenarios. The 2023 edition provides the most current test method of determining the heat release and smoke generation of pipe insulation and pipe insulation assemblies under controlled laboratory conditions.

Notable changes include:

• Updates to the latest referenced codes and standards
• Revisions to the annex to support the 2023 edition of NFPA 274
