Standards Guide
A HIP project should review material standards, pressure-vessel compliance, the quality system, process records, and acceptance evidence as one connected framework.
Powder bed fusion material standards such as ASTM F3301 (AM part heat treatment and HIP post-processing specifications) and ASTM F3184/F3318 are often cited, and the pore closure effect needs to be evaluated together with the part heat treatment status and non-destructive testing (such as CT) requirements.
Common basis include AMS 2175 (general specification for castings HIP), AMS 2185 (titanium and titanium alloy castings HIP) and OEM-specific process specifications; customers usually require batch data, heat treatment status certificate and Nadcap AC7102 (heat treatment special process certification) audit information.
Titanium alloy implants HIP usually refer to standards such as ASTM F1801 (porous metal coating fatigue evaluation) and ASTM F3001/F2924 (powder bed fusion Ti-6Al-4V ELI), emphasizing clean atmosphere, material biocompatibility, surface quality and complete traceability records under the ISO 13485 system.
The design and acceptance of high-pressure vessels require a clear regulatory path: the North American market usually follows the ASME BPVC Volume VIII, the EU market applies PED 2014/68/EU, and the domestic TSG 21 Mobile/Fixed Pressure Vessel Safety Technical Supervision Regulations require complete safety valve, rupture disc and interlock test documents.
ISO 9001 is a basic quality management system requirement; the aviation supply chain usually superimposes AS9100, and the special heat treatment process needs to meet the Nadcap AC7102 (heat treatment) or AC7122 (non-destructive testing) audit elements.
Factory and on-site acceptance should cover pressure maintenance testing, temperature uniformity mapping (Temperature Uniformity Survey, refer to AMS 2750 similar logic), safety interlocks, alarm records, HMI permissions and data report samples.
Link pressure, temperature, and time curves plus alarm history to the batch ID, load list, and inspection results. The resulting evidence chain should support customer quality-system audits such as AS9100 or ISO 13485, not merely document equipment operation.
