The Smoke and Fire Laboratory integrates two large groups of fire reaction tests: tests accredited by the Portuguese Accreditation Institute (IPAC) and those that, despite not having accreditation, may be relevant for the development of new products and to assess their behaviour when subjected to a fire.

Tests accredited by IPAC

• Determination of the gross heat of combustion (calorific value)
• Non-combustibility test
• Single Burning Item test (SBI)
• Single-flame source test

• Electrical burner test
• Rate of flame spread test
• Dripping test

• Test to determine the horizontal burning rate
• Test to determine the melting behaviour 

Non-accredited tests

• Determination of smoke density/opacity
• Determination of gases toxicity
• Fire behaviour of plastic materials

• Textile-glass and mineral-filler content – Calcination method
• Textile-glass and mineral-filler content – Digestion method
