# WIA-fire-resistant-material PHASE 1 — DATA-FORMAT Specification **Standard:** WIA-fire-resistant-material **Phase:** 1 — DATA-FORMAT **Version:** 1.0 **Status:** Stable This document defines the canonical data-format layer for WIA-fire-resistant-material. The standard covers the persistent record shapes that a fire-resistant-material producer (a building- material manufacturer of cementitious panels, gypsum boards, intumescent coatings, mineral-wool insulation, fire-rated glass, fire-rated doors and door assemblies, fire-protective fabrics, or flame-retardant polymers), a third-party fire- testing laboratory, a notified body issuing the EU Construction Products Regulation conformity assessment, an Authority Having Jurisdiction inspecting a building-code submission, a fire- investigation expert, and a public-procurement authority running a building-safety programme maintain when classifying a material's fire performance, registering its calibrated test result against an internationally recognised test method, declaring its reaction-to-fire and resistance-to-fire performance, and tracking the test-laboratory accreditation chain. Records are consumed by the building designer integrating the material into a fire-protection design, by the building official auditing the construction- product Declaration of Performance, by the insurance underwriter pricing the building's risk profile, and — where the product is sold across borders — by the customs authority verifying the classification reported on the commercial invoice.

Implementations covered include: - A cementitious-panel manufacturer publishing the EN 13501-2 resistance-to-fire classification of the panel against a separating load-bearing element test under EN 1364. - A gypsum-board manufacturer publishing the EN 13501-1 reaction-to-fire classification (A2- s1, d0) anchored to ISO 1716, ISO 1182, and EN 13823 test reports. - A mineral-wool insulation manufacturer publishing the same classification anchored to the same test set. - An intumescent-coating manufacturer publishing EN 1363-1 / EN 13381-series fire-protection performance against structural-steel exposure. - A fire-rated-door-assembly manufacturer publishing the EN 1634 or NFPA 252 fire- resistance classification. - A flame-retardant polymer manufacturer publishing the ASTM E84 surface-burning classification (Class A, B, or C) against the Steiner-tunnel test. The reaction-to-fire envelope, the resistance-to- fire envelope, and the surface-burning envelope receive distinct encodings in this PHASE; the additional safeguards required by each classification regime are encoded in PHASE-3 §3. ##

§9 Manifest Implementations publish a signed manifest carrying `standardSlug` (constant value "fire-resistant- material"), `version`, `implementation`, the operator's `accreditationStatus`, and the `profile` declaration that selects which of the optional records (reaction-to-fire, resistance-to- fire, DoP, AHJ audit) the implementation supports. The manifest is signed using a key whose public part is published on the operator's `.well-known/wia/fire-resistant-material/` discovery endpoint declared in PHASE-2.
