ASTM D2898-10 (2024) PDF

Full title and description

ASTM D2898-10(2024) — Standard Practice for Accelerated Weathering of Fire‑Retardant‑Treated Wood for Fire Testing. Describes controlled accelerated conditioning methods (wetting, drying, leaching, temperature, and UV exposure) for fire‑retardant‑treated wood prior to evaluation in fire response tests.

Abstract

This practice specifies four accelerated conditioning methods to simulate environmental degradation (leaching, drying, UV exposure) of pressure‑impregnated fire‑retardant treatments on wood products. Conditioned specimens are intended for subsequent fire performance testing (for example, specimens used in Test Methods E84, E108, and E1354). Method A is normally specified for regulatory/exterior applications.

Scope

The standard addresses durability of fire‑retardant treatments in pressure‑impregnated wood products by exposing specimens to accelerated cycles of wetting, drying, temperature variation, and, in specified methods, ultraviolet (UV) exposure. Four conditioning methods are described and are intended to prepare specimens for subsequent fire response tests (e.g., E84, E108, E1354). The practice is limited to treated wood products suitable for fabrication into standard fire test specimens.

Key topics and requirements

• Four defined conditioning methods that simulate leaching, drying, thermal cycling and, for selected methods, UV exposure prior to fire testing.
• Method A recommended/typically specified for regulatory use and for exterior‑exposed fire‑retardant‑treated wood.
• Applicability limited to wood products treated by pressure impregnation with fire‑retardant chemicals (not surface‑only coatings).
• Specimens must be suitable for subsequent fire response test methods (references include E84, E108, E1354 and related fire tests).
• Procedure intended to simulate environmental effects that may alter fire performance (leaching of retardant, surface degradation, moisture cycling).

Typical use and users

Used by fire‑testing laboratories, treated‑wood manufacturers, third‑party testing organizations, building code/regulatory bodies, and researchers evaluating the longevity and fire performance of fire‑retardant treatments. Typical applications include preconditioning specimens prior to flame‑spread, cone calorimeter, and other fire response tests required for product qualification or code compliance.

Related standards

Referenced fire test methods commonly used with this practice include ASTM E84 (surface flame spread), ASTM E108 (roof covering and deck tests / building construction fire tests), ASTM E1354 (cone calorimeter), and other ASTM fire‑performance test methods for treated wood. The practice is part of the D‑07 committee family of standards covering wood and fire testing.

FAQ

Q: What is this standard?

A: ASTM D2898-10(2024) is a concise practice that defines accelerated conditioning (weathering) methods for fire‑retardant‑treated wood to simulate environmental aging prior to fire performance testing.

Q: What does it cover?

A: It covers four conditioning methods (wetting, drying, temperature cycling, and UV exposure in specified methods), applicability to pressure‑impregnated fire‑retardant treatments, and preparation of specimens for subsequent fire response tests such as E84, E108, and E1354.

Q: Who typically uses it?

A: Fire testing laboratories, treated‑wood manufacturers, product certification bodies, code officials, and research organizations use the practice to precondition specimens before conducting fire performance evaluations.

Q: Is it current or superseded?

A: The D2898‑10 text has been reaffirmed and is listed as active in the 2024 revision cycle (reported as D2898‑10R24 / D2898‑10(2024)), so it is current as of the 2024 reaffirmation. Check ASTM publications for any later revisions.

Q: Is it part of a series?

A: It belongs to the ASTM D standards maintained by Committee D07 (Wood) and Subcommittee D07.07; it is closely associated with other ASTM fire and wood standards used together for evaluating treated wood fire performance.
