Overview

EN 15715:2009 - Thermal insulation products: Instructions for mounting and fixing for reaction to fire testing (factory made products) is a CEN European Standard that specifies how factory-made thermal insulation products must be mounted and fixed when subjected to reaction-to-fire tests. The standard ensures reproducible laboratory conditions so that fire performance test results (ignitability, spread, heat release) are comparable and valid for product assessment and classification.

Key topics and requirements

• Scope & principle: Defines the purpose and testing principle for mounting specimens to assess reaction to fire.
• Product and installation parameters: Lists required parameters to be recorded (material type, thickness, geometry) and installation conditions affecting test outcomes.
• Mounting and fixing rules: Detailed instructions on how to mount and mechanically fix specimens for:
  • Ignitability tests (EN ISO 11925-2) - single-flame exposure methods.
  • Single Burning Item (SBI) tests (EN 13823) - room-corner test assessing heat release and flaming behavior.
• Standardised assemblies: Procedures for testing products installed in assemblies that simulate end-use applications (walls, façades, roofs, pipes).
• Field of application / validity: Guidance on the applicability of test results across product families and similar installations.
• Product-specific annexes: Annex A contains product-specific mounting parameters and tables for a wide range of materials (mineral wool, EPS, XPS, PUR/PIR, phenolic foam, cellular glass, wood-based insulants, elastomeric foams, calcium silicate, polyethylene foam, etc.).

Applications and who uses it

• Manufacturers use EN 15715 to prepare specimens and test reports that reliably reflect in-service fire behaviour and to support CE marking or product declarations.
• Test laboratories follow the standard to ensure consistent mounting and fixing procedures during EN ISO 11925-2 and EN 13823 testing.
• Certification bodies and regulators use the standardised test set-up as part of assessment and product classification workflows.
• Specifiers, architects and installers rely on test-based fire performance data produced using EN 15715 to select suitable thermal insulation for building envelopes, façades, roofs and services insulation where reaction-to-fire performance is critical.

Related standards

• EN ISO 11925-2 - Ignitability (single-flame exposure)
• EN 13823 - Single Burning Item (SBI) test
• Often used together with fire classification standards from the EN 13501 family for assigning reaction-to-fire classes.

EN 15715:2009 is essential for ensuring repeatable, reliable reaction-to-fire test results for factory-made thermal insulation products and for translating laboratory data into practical, code-compliant product information.
