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.
This standard is the benchmark for brass castings used in valves, flanges, and pipe fittings in the Japanese industrial market and beyond. If you have searched for the term "jis h 5114 pdf", you are likely looking for the official document to verify material properties, chemical compositions, or mechanical requirements.
This article provides a comprehensive overview of the JIS H 5114 standard, its specifications, common grades, how it compares to other international standards (like ASTM or DIN), and—most importantly—legitimate ways to find and download the JIS H 5114 PDF. jis h 5114 pdf
The standard requires tensile tests to verify quality. Properties vary significantly depending on the casting method (Sand mold vs. Metal mold).
| Symbol | Tensile Strength (min) | Elongation (min) | Brinell Hardness (HB) | | :--- | :--- | :--- | :--- | | CAC301 | 430 N/mm² | 20% | 100+ | | CAC102 | 250 N/mm² | 15% | 80+ | | CAC701 | 440 N/mm² | 20% | 110+ | | CAC403 | 250 N/mm² | 20% | 70+ | In the world of industrial manufacturing, material standards
Note: Values above are for Sand Mold castings (S). Metal Mold castings (M) typically exhibit higher strength.
The standard specifies minimum requirements for: The standard specifies minimum requirements for:
Crucially, the PDF notes that these values are for standard test specimens, not the actual produced part. Real castings may vary due to porosity.
If you cannot find the JIS PDF, you might substitute another standard. However, substitution requires caution.
| Standard | Grade | Similar to JIS H 5114 | Key Difference | | --- | --- | --- | --- | | ASTM B62 | C83600 (Leaded Red Brass) | Roughly CAC202 | Different Cu% (84-86% vs 56-60%). Not a direct substitute. | | ASTM B584 | C84400 | Similar to CAC203 | Mechanical properties differ slightly. | | EN 1982 | CC491K (CuZn5Pb) | Approximates CAC202 | Different zinc tolerance. | | ISO 1338 | CuZn33Pb2 | Matches some grades | Not all ISO grades align perfectly. |
Conclusion: Always get the jis h 5114 pdf for validation. Do not assume a direct equivalence without engineering approval.
