Management System Certification & Export Compliance

When European and South American buyers audit a hydraulic component supplier, their first questions are: is the system certificate valid for our scope, which standard governs cylinder mounting dimensions, and what documents are needed to export into the EU. Below are the standards and document set we actually work to.

ISO 9001 Quality Management System
Incoming inspection, assembly, hydrostatic testing and shipment release for hydraulic valves, pumps and cylinders are all controlled under the system. Scope coverage is checked against the client certificate original; anything outside scope is reviewed separately as a non-standard item.
ISO 6020 / 6022 / 6023 Cylinder Mounting Dimensions
Bore, stroke, piston rod diameter and mounting flange hole spacing are drawn to the standard series, with actual dimensions on the nameplate so customers can match machine interfaces directly.
ISO 4413 Hydraulic Fluid Power Safety
Valve blocks, accumulators and piping accessories are checked against this standard for rated pressure, burst and leakage risk items. Manifold blocks come marked with port flow bore sizes and working pressure.
ISO 4406 Fluid Cleanliness
Assembly and testing run under graded cleaning throughout, with valve port sampling cleanliness held to 18/16/13 targets. Cleanliness and leakage test records ship with the goods.
CE and PED 2014/68/EU Applicability
Our products are supplied as components, so whether CE marking and the Pressure Equipment Directive apply is confirmed order by order against the specific contract product. Once confirmed, we issue a declaration of incorporation only; the declaration text is not written on this page.
Shipping Documents for Europe and South America
Packing list, invoice, certificate of origin, pressure test report and material certification are issued to EN 10204 3.1. Documents required for import clearance in the destination country follow confirmation by the client and their local customs broker.

Common market-entry requirements; applicability and documentation are subject to the destination country's current regulations and mutual confirmation.

Send the model number or old-part drawing, and we will verify the interface and reply with a sample plan

Provide the matching REXROTH model, pressure rating and flow requirement, and we will return a manufacturable sample plan and quotation within 7 days.
