Abstract
Overview
ISO 3299:1994 is an International Standard issued by the International Organization for Standardization (ISO) that specifies the purity requirements and test methods for photographic-grade 1-phenyl-3-pyrazolidinone, commonly known as phenidone. This second edition replaces the original 1976 version and sets stringent criteria to ensure the chemical’s suitability in photographic processing. The standard is essential for manufacturers, laboratories, and quality control professionals involved in producing or using photographic processing chemicals.
