Overview

ISO 18665:2022 - Traditional Chinese medicine - Herbal decoction apparatus defines safety, material, performance and testing requirements for herbal decoction equipment with design pressures less than 0.1 MPa. Applicable to both hermetic (airtight) and non‑hermetic (open to atmosphere) decoction apparatus, the document covers devices used for individual prescriptions, commercial production and the decocting modules of integrated decoction‑and‑package systems. This second edition (2022) updates the 2015 edition with editorial and normative-reference revisions.

Key topics and technical requirements

The standard sets practical, testable requirements across several areas:

• Scope and definitions - clarifies hermetic vs non‑hermetic decoction apparatus and applicability to individual and commercial use.
• Materials - substances in direct contact with decoctions must be non‑toxic, corrosion‑resistant, non‑shedding and high‑temperature‑resistant, and comply with corresponding hygienic standards. Lubricants must meet ISO 21469 requirements.
• Surface quality - external surfaces must be neat and clean; metal parts in contact with decoction: **surface roughness
