Furnace tests, ratings, and codes for structural fire evidence — Ch. 37 orientation.

Scope

CivilTech notes on structural fire behaviour and design. Not a substitute for project codes, approvals, or peer review.

Regulatory context. South African projects follow National Building Regulations, SANS 10400, and cited material standards; use this material as orientation only.

Using this page

  1. Context — Cross-check these notes with your project fire strategy and the code edition on the job.
  2. Tools — The Fire Engineering page has ISO 834 and steel-retention calculators for quick checks.
  3. Approval — Fire resistance and structural fire design remain subject to the local authority and appointed engineers.

Fire engineering — Testing and standards

Section 10 — Furnace tests, classification, and how they relate to structural design.

Standard fire tests

Furnace exposure to a standard temperature–time curve yields fire resistance ratings (e.g. R, E, I) for assemblies under defined support and loading.

Limits

Specimen size, loading, and boundary conditions may not match the as-built structure; extrapolation and engineering judgement are regulated.

Codes

National regulations and SANS product/test standards define what evidence is acceptable for compliance in South Africa.
