JIS H 5114 is a Japanese Industrial Standard (JIS) titled "Brass castings for valves, flanges and fittings". It specifically covers copper-zinc alloy (brass) castings used under pressure for water, oil, gas, and steam services.
The standard was originally established to unify the quality of brass castings produced by foundries across Japan. Today, it is referenced globally, especially in projects involving Japanese-designed equipment, shipbuilding, plumbing systems, and industrial machinery.
In the world of industrial manufacturing, material standards are the silent guardians of quality, safety, and interoperability. For engineers, procurement specialists, and quality assurance teams working with brass components, one standard frequently appears on blueprints and purchase orders: JIS H 5114. jis h 5114 pdf
This standard is the benchmark for brass castings used in valves, flanges, and pipe fittings in the Japanese industrial market and beyond.
