D4416-09 – Standard Test Method Technical Guide

📋 Specification Scope and General Requirements

ASTM D4416‑09 (Reapproved 2023) establishes the standard specification for glacial acrylic acid (propenoic acid, vinyl formic acid) of 99.0 % grade. This standard is intended for materials used in paints, varnishes, lacquers, and related coating products. It provides a definitive benchmark for quality, defining limits for purity, water content, color, inhibitor concentration, and dimer content.

All values in the standard are in SI units. Section 1.2 specifies that conformance determination requires test values to be rounded “to the nearest unit” in the last right‑hand digit of the specification limit, strictly following the rounding‑off method of Practice E29. The standard explicitly states it does not address all safety concerns (Section 1.5) and defers to the supplier’s Safety Data Sheet (SDS) for hazard guidance (Section 1.4).

📊 Key Physical and Chemical Properties

Section 3 of the standard details the mandatory conformance requirements for glacial acrylic acid. The material must pass all the specified limits as listed below.
