Fire curve and criteria
The standard curve is T = 345 log₁₀(8t + 1) + 20. Elements are judged on load-bearing capacity, integrity and insulation, in the same way as the EN 1363 family. Our CNAS accreditation is recognised under the ILAC Mutual Recognition Arrangement, which many national authorities accept.
Frequently asked questions
Which markets accept ISO 834 reports?
Many countries in the Middle East, South and Southeast Asia, Africa and Latin America reference ISO 834 or a national standard based on it. Check the local regulation and whether a report from an ILAC-recognised laboratory is accepted.
