📋 QUICK ANSWER — Three Standards, One Fire Curve
BS 476, AS 1530.4, and MS 1073 all test fire-rated glass to the same ISO 834 time-temperature curve. The differences are in how performance is classified (E/EI/EW vs FRL vs MS 1073 categories), who accredits the lab (UKAS vs NATA vs SIRIM), which building code references them (Approved Document B vs NCC Section C vs UBBL), and what certification chain is required for project approval. This article compares all three side by side — ratings, methods, regulatory hooks, document packages, and mutual recognition paths.

Why Compare These Three Standards?
If you specify fire-rated glass across the UK, Australia, and Malaysia — or you're a manufacturer supplying all three markets — you face a puzzle. The fire is the same. The glass behaves the same. Yet the compliance paperwork, certification labels, and regulatory approval chains are fundamentally different in each jurisdiction.
This article is for:
- Architects and specifiers working on projects in multiple Commonwealth markets
- Facade consultants who need to understand which test evidence satisfies which building code
- Importers and distributors evaluating whether a factory's certification package covers their market
- Building certifiers and fire engineers assessing equivalency between foreign test reports and local requirements
One critical fact before we dive in: all three standards use the identical ISO 834 time-temperature curve. A piece of glass that survives 60 minutes at 945°C under BS 476 will behave identically under AS 1530.4 and MS 1073. The divergence is entirely in the certification, documentation, and regulatory framework — not in the fire science.
1. BS 476 — United Kingdom
The standard
BS 476-20 defines the general method for fire resistance testing. BS 476-22 is the specific method for non-loadbearing elements — this is the relevant part for fire-rated glazing systems. The alternative European path is EN 1364-1 (non-loadbearing walls) and EN 1634-1 (doors), referenced by the harmonized standard EN 16034.
How ratings work
| Classification | Meaning | Tested Property |
|---|---|---|
| E (e.g., E30) | Integrity — no flame/hot gas passage | Cotton pad, gap gauge, sustained flaming |
| EI (e.g., EI60) | Integrity + Insulation — also limits temperature rise ≤140°C avg, ≤180°C point | Thermocouples on unexposed face |
| EW (e.g., EW30) | Integrity + Radiation control ≤15 kW/m² at 1m | Radiometer at 1m from unexposed face |
Regulatory hook: Approved Document B
"Where fire-resisting glazing is used, it should be tested to BS 476-22 or the equivalent European standard BS EN 1364-1, and installed in a frame that has been tested as a complete assembly."
— Approved Document B, Volume 2 (Fire Safety), 2019 Edition incorporating 2022 amendments
Certification path
- Fire test at UKAS-accredited lab (BRE, Warringtonfire, Exova, IFC)
- Third-party product certification — CERTIFIRE, LPCB, or IFC scheme (not mandatory but strongly expected by Building Control)
- UKCA / CE marking — to EN 16034 (industrial doors) or EN 14449 (glass in building) as applicable
- Building Control approval — local authority or Approved Inspector reviews test evidence and installation details
2. AS 1530.4 — Australia
The standard
AS 1530.4 is the Australian Standard for fire resistance tests on building elements. It covers walls, floors, ceilings, columns, beams, door sets, and glazing. Unlike BS 476, there is no separate "glazing-only" test part — glazing is tested as an element within a representative supporting construction.
How ratings work: FRL
Australia uses the Fire Resistance Level (FRL) expressed as three numbers separated by slashes:
Structural Adequacy / Integrity / Insulation
e.g., -/60/30 = no structural requirement, 60 min integrity, 30 min insulation
For glazing, structural adequacy is always "-" (dash) because glass is non-loadbearing. So the rating becomes -/integrity/insulation.
Regulatory hook: NCC 2025 Section C
"Where a fire-resisting construction is required, it must comply with Specification C1.1 and AS 1530.4."
— National Construction Code 2025, Volume 1, Section C, Clause C3.2
Certification path
- Fire test at NATA-accredited lab (CSIRO, Warringtonfire Australia, BRANZ)
- CodeMark certification (optional but strongly recommended) — ABCB-administered product certification scheme demonstrating compliance with NCC Performance Requirements
- NATA-endorsed test report — must state the precise assembly: glass make/model, frame profile, glazing method, fixing centres
- Direct Application / Extended Application statement — defines permissible size range, aspect ratio limits, and configuration scope
- Certifier sign-off — Registered Building Certifier or Fire Safety Engineer reviews evidence against NCC Performance Requirements A5G3(d)
Key difference: Australia places heavier emphasis on the installed system matching the tested prototype exactly. A "glass-only" report is worthless — the certifier will reject it. The entire assembly (glass + frame + gasket + fixing method + perimeter seal) must be covered by the test evidence.
3. MS 1073 — Malaysia
The standard
MS 1073:2015 is the Malaysian Standard for fire resistance tests on glazed elements. It is the primary compliance standard referenced by BOMBA (Fire and Rescue Department of Malaysia) under the Fire Services Act 1988 (Act 341) and the Uniform Building By-Laws 1984 (UBBL).
How ratings work
Malaysia uses the UBBL 7th Schedule fire resistance periods, categorized by building element type rather than a standalone classification system:
| UBBL Clause | Application | Rating | MS 1073 Equivalent |
|---|---|---|---|
| By-Law 153 | Fire door vision panel (residential ≤18m) | FD30 | EI30 |
| By-Law 154 | Fire door vision panel (commercial/industrial) | FD60 | EI60 |
| By-Law 162 | Compartment wall glazing | FRP 60–120 | EI60–EI120 |
| By-Law 166 | Protected lobby/staircase glazing | FRP 60 | EI60 |
| By-Law 169 | Atrium/vertical opening glazing | FRP 120 | EI120 |
Regulatory hook: The Three-Layer System
Malaysia's compliance framework is the most complex of the three, requiring three independent certifications:
- SIRIM QAS product certification — Fire test to MS 1073, factory audit, annual surveillance. Certificate valid 1 year.
- CIDB COA (Certificate of Approval) — Under Act 520 Fourth Schedule, mandatory for float glass (MS 1135), safety glass, and aluminium extrusions (MS 2289). Required for import clearance.
- BOMBA FSC (Fire Safety Certificate) — Under Act 341, required for building occupancy. Involves on-site inspection verifying that the installed glazing matches the tested configuration.
Critical: Malaysia is the only market of the three where installation-level approval (BOMBA FSC) is a legally separate step from product certification. Even with perfect SIRIM and CIDB documentation, if the on-site installation deviates from the tested configuration, BOMBA will withhold the occupancy permit.
4. Head-to-Head: Key Differences That Affect Your Project
4.1 Documentation Package Size
| Market | Minimum Documents Required | Pages (typ.) |
|---|---|---|
| UK (BS 476) | Fire test report + UKCA/CE cert + installation instructions | ~15–25 |
| AU (AS 1530.4) | Fire test report + CodeMark cert + Direct Application Statement + CAD installation details + FPC cert | ~30–50 |
| MY (MS 1073) | Fire test report + SIRIM QAS cert + CIDB COA + BOMBA FSC application + CAD installation details + DAS + FPC cert | ~45–70 |
4.2 Mutual Recognition Reality Check
| From → To | Acceptance | Conditions |
|---|---|---|
| BS 476 → AS 1530.4 | Not directly accepted | Requires Performance Solution under NCC A5G3(d) with engineering assessment |
| AS 1530.4 → BS 476 | Not directly accepted | Requires UKAS-accredited equivalency review or re-test |
| BS 476 → MS 1073 | Supporting only | Accepted as supplementary evidence; SIRIM equivalency review required |
| AS 1530.4 → MS 1073 | Supporting only | Same — SIRIM-recognized equivalency assessment mandatory |
| EN 1634-1 → BS 476 | Largely accepted | CE/UKCA marking covers both; ADB explicitly references EN equivalents |
Bottom line: No free lunch on cross-market recognition. If your project is in Malaysia, you need MS 1073 evidence. If it's in Australia, you need AS 1530.4 evidence. The safest, fastest path is sourcing glass that has already been tested and certified to the target market's standard — not gambling on an equivalency review.
4.3 Certification Renewal Frequency
| Market | Certification | Validity | Renewal Trigger |
|---|---|---|---|
| UK | CERTIFIRE / LPCB | 5 years (with annual surveillance) | Annual factory audit + biennial audit testing |
| AU | CodeMark | 3 years | Re-assessment of test evidence + factory audit |
| MY | SIRIM QAS PCS | 1 year | Annual full surveillance: factory re-inspection + random sample test |
Malaysia's 1-year SIRIM renewal cycle is the most demanding. An expired SIRIM certificate — even by one day — triggers automatic BOMBA rejection. Projects with long construction timelines must plan for certificate renewal mid-project.
