HPS hydraulic cylinder production is carried out within the scope of 9 international standards. The purpose, scope and the way each standard is applied within HPS are listed in detail below.
Global hydraulic standard: acceptance test, fatigue test, safety, mounting dimensions.
German national standard: tube raw material (DIN 2391 ST52) and classic cylinder reference.
European standard: modern European equivalent of DIN (EN 10305) and material certificate (EN 10204).
US/Canada hydraulic standard: mounting compatibility (T3.6.7R).
Scope: Hydraulic cylinder acceptance test standard. Defines the seal + static pressure test procedure at 1.5 times the nominal pressure.
HPS application: All production cylinders are tested per the ISO 10100 acceptance test procedure. The test report is provided with the shipment on request.
Scope: It defines the fatigue pressure test method for metal pressure-containing envelopes of hydraulic fluid power components. It establishes the test procedure for life verification under cyclic pressure; the rating of results is covered in ISO/TR 10771-2.
HPS application: Performed on request within a custom design or OEM approval process. Not applied on standard production cylinders, where the ISO 10100 acceptance test is sufficient.
Scope: General rules for hydraulic power system design + safety. Proof test, pressure limiting, seal safety requirements.
HPS application: Compliance with the ISO 4413 safety requirements is ensured during the design + production process.
Scope: Single-rod tie-rod cylinder compact series mounting dimensions (MF1-MS7). 16 MPa nominal pressure.
HPS application: ISO 6020-2 dimensional compliance is ensured in the standard series: replacement cylinder compatibility.
Scope: Heavy-duty 25 MPa nominal pressure single-rod cylinder mounting dimensions.
HPS application: ISO 6022-compliant series for heavy industrial applications (press, heavy machinery).
Scope: Cold drawn seamless steel tube: cylinder body raw material standard. ST52 (1.0580) steel grade.
HPS application: All standard cylinder bodies are supplied as certified DIN 2391 ST52 (BKS: cold-finished, stress-relief annealed) honed precision tube.
Scope: Modern European equivalent of DIN 2391. E355 (1.0580) steel grade, precise dimensional + surface tolerance.
HPS application: Exactly equivalent to DIN 2391 ST52. Delivered with the EN 10305-1 reference for European customers.
Scope: Material certificate type: manufacturer-signed mill test report (MTR), chemical composition + mechanical property report.
HPS application: Rod + body raw material is supplied with the EN 10204 3.1 certificate, kept for the traceability chain.
Scope: US/Canada market mounting dimension standard. Similar to ISO 6020-2 but based on imperial units.
HPS application: NFPA T3.6.7R-compliant variant production for North American customers, on request.
Referencing a standard, for example "ISO 6020-2 dimensionally compliant", means that the cylinder is manufactured in that dimensional class. A documented third-party certificate (CE, ISO 9001) is a separate audit process.
The actively documented certificates at HPS are listed in detail on the Quality & Certificate page.
DIN 2391, EN 10305-1, EN 10204 3.1: raw material quality and certificate reference. Verified during the HPS procurement process.
ISO 6020-2, ISO 6022, NFPA T3.6.7R: cylinder dimension + mounting compatibility reference. Compliant across the HPS standard series.
ISO 10100, ISO 10771-1, ISO 4413: acceptance test + fatigue test (cyclic pressure endurance) + safety. HPS applies the 10100 acceptance test on every cylinder.
