Certificates and test reports are shared in the shipment file. Market compliance marks (CE, EAC) are documented on customer request. From the raw-material certificate to the pre-shipment pressure test, the entire process is fully traceable.
The documents below are held in the corporate archive. Click on a certificate image to open the high-resolution version. For renewal cycles, the current copy is requested from the engineering team.
Conformity with the European Union machinery safety directive. Mandatory marking for EU and UK export. Hydraulic cylinder scope: tipper, forklift, crane, waste vehicle, concrete pump, manlift and related applications.
Quality management system certification. Audits design, production and sales processes against ISO 9001:2015 standards. Renewal confirmed on request.
Legal trademark registration of HPS. Registered with the Turkish Patent and Trademark Office under Nice classification 07 (machinery), 12 (vehicles), 35 (advertising) and 37 (construction services).
Eurasian Economic Union conformity mark. Mandatory for the CIS market. Issued on customer request.
Factory test report for tube (DIN 2391-2 ST52 / E355), rod (CK45 / 42CrMo4) and plating (hard chrome ~30 µm). Raw-material supply certificate is traceable.
Before shipment, every cylinder undergoes a 1.5× rated pressure test. The test result certificate is delivered to the customer in the shipment file.
Six-stage traceability from raw-material intake to shipment dispatch. Each stage produces a certificate or test report; the complete file is delivered to the customer together with the shipment.
The HPS test procedure is carried out against 3 international standard references. The scope and reporting format of each test procedure is detailed below.
Sealing + static pressure test at 1.5 times the rated pressure. Hold under proof pressure per ISO 10100 (typically ~10 s). Visual leak + pressure drop check.
Fatigue life test of metal body + head + base. Arranged per customer spec. Test result observes cracking or permanent deformation.
General safety rules for hydraulic power systems. Proof test pressure, pressure limitation, sealing safety requirements.
Standard titles are a dimensional reference; certificate documents are issued per product and shared together with the customer product spec file.
HPS manufactures under its registered trademark; all certificates and documents above are issued in the name of our legal entity.
