A: Request a "Conformance to ASME B3112" statement from your powder supplier. Then perform at least one independent test (e.g., flow rate) to verify.
ASME B31.12 is more than a technical manual; it is the foundational safety document for the hydrogen economy. By providing standardized methods for material qualification and system design, it enables engineers to build the infrastructure necessary for a sustainable future. As technology evolves, the code continues to be updated, ensuring that the path to a hydrogen-powered world remains safe, reliable, and scientifically sound.

Every shipment must include a Certificate of Conformance (CoC) with raw data, not just pass/fail statements. The standard also mandates a Material Test Report (MTR) that follows the powder through each reuse cycle. A: Request a "Conformance to ASME B3112" statement
The ASME B31.12 code provides a critical framework for ensuring the safe and reliable transportation of hydrogen gas through pipelines. The standard addresses key aspects of pipeline design, materials, fabrication, installation, testing, and inspection. Users can purchase the ASME B31.12 PDF from the ASME website or through other standards distributors. The standard also mandates a Material Test Report
To put it simply, this standard provides a uniform methodology for evaluating the performance of metal 3D printers that use a laser to melt metal powder layer by layer.
Hydrogen can cause "hydrogen embrittlement" in certain metals; B31.12 provides guidelines on compatible materials.
