Overview

ISO 14952-6:2003 - "Space systems - Surface cleanliness of fluid systems - Part 6: Precision‑cleaning processes" defines precision-cleaning processes and procedures for parts, components and systems used in flight‑critical fluid applications. It applies equally to ground support equipment, launch vehicles and spacecraft, and is intended to establish repeatable cleaning, analysis and verification methods to meet required cleanliness levels for space fluid systems.

Key topics and requirements

Scope and applicability: Precision cleaning for hardware used in flight‑critical fluid systems on spacecraft, launch vehicles and ground support equipment.

Personnel and facilities: Cleaning and disassembly of precision components must be performed by trained, certified personnel and in environments compatible with component cleanliness requirements.

Environmental, health & safety: The standard permits use of hazardous materials but assigns responsibility to the cleaning organization for compliant storage, handling, waste minimization and reporting.

Precleaning and surface treatment: Critical surfaces must be precleaned to remove dirt, grease, scale and corrosion; metallic parts may require passivation or coatings to prevent latent corrosion.

Materials compatibility: Processing fluids and materials must be evaluated for corrosion, stress‑corrosion cracking, embrittlement, leaching, residue, and other effects on metallic and non‑metallic materials.

Final rinsing and cleanliness limits: Final rinse fluids must meet particle and residue criteria and be compatible with the system fluid; nonvolatile residues are limited (see standard: ≤ 10 mg per 500 ml). Specific particle size/count limits and sampling methods are defined in the document.

Verification and inspection: Visual inspection and analytical verification shall be performed per ISO 14952‑3 (analytical procedures for nonvolatile residues and particulates) or by customer‑approved equivalent methods.

Packaging and protection: Approved coverings, cleaned packaging materials, nitrogen purge (ISO 14951‑3 Type A), double‑bagging and certification tags are required to preserve cleanliness during storage/transport.

Field cleaning & excepted components: Procedures and approvals for in‑field cleaning, decontamination of propellant‑exposed items, temporary hardware installation and system integrity tests (e.g., pressure validation) are specified.

Applications and users

Aerospace OEMs and suppliers producing fluid system components (valves, tubing, vessels)

Ground support and launch operations teams conducting maintenance or refurbishment

Cleaning organizations, subcontractors and ISO/quality managers who establish cleaning processes and acceptance criteria

Systems engineers and QA professionals responsible for material compatibility, verification and packaging of flight hardware

Keywords: ISO 14952-6, precision-cleaning, surface cleanliness, fluid systems, spacecraft cleaning, launch vehicle maintenance, nonvolatile residues, particulate contamination, cleanroom cleaning.
