Ta del standarda EN 10305 določa tehnične dobavne pogoje za hladno vlečene varjene cevi s krožnim prečnim prerezom za uporabo v hidravličnih in pnevmatičnih tlačnih vodih.
Cevi v skladu s tem delom standarda EN 10305 imajo natančno opredeljene tolerance za mere in določeno največjo površinsko hrapavost.
Za dovoljene ravni tlaka in najvišje temperature je odgovorna stranka v skladu s stanjem tehnike in ob uporabi varnostnih koeficientov, določenih v veljavnih predpisih, kodeksih ali standardih. Kar zadeva ustreznost razpona nižjih temperatur, so zahteve glede udarne moči podane pri 0 °C.
OPOMBA: Ko bo ta standard objavljen v Uradnem listu Evropske unije (OJEU) v okviru Direktive 97/23/ES, bodo zagotovila o skladnosti z osnovnimi varnostnimi zahtevami (ESR) Direktive 97/23/ES omejena na tehnične podatke o materialih, navedene v tem evropskem standardu, standard pa ne bo zagotavljal ustreznosti materiala za določen element opreme. Zato bo potrebno oceniti tehnične podatke, podane v tem standardu za materiale, glede na zahteve zasnove določenega elementa opreme, da se zagotovi, da so izpolnjene osnovne varnostne zahteve Direktive o tlačni opremi.

Overview
EN 10305-6:2016 - Steel tubes for precision applications - Part 6 defines the technical delivery conditions for welded cold drawn tubes of circular cross section intended for hydraulic and pneumatic power systems. The standard focuses on precision steel tubes with strict dimensional tolerances and specified surface roughness, and it sets requirements for manufacture, inspection and documentation. Customers remain responsible for selecting allowable pressure ratings and maximum operating temperatures in line with applicable safety coefficients and regulations.
Key topics and technical requirements
- Scope and purpose: Applies to welded cold drawn precision tubes for hydraulic and pneumatic circuits; impact energy requirements for low temperatures are given at 0 °C.
- Dimensional control: Tubes are characterized by precisely defined tolerances (outer diameter and wall thickness preferred) and geometric requirements.
- Surface quality: Specified surface roughness and options for reduced internal roughness and surface roughness measurement.
- Mechanical verification: Mechanical properties verified by tensile testing and the drift-expanding test (now accepted alongside tensile tests).
- Non-destructive testing (NDT): Options include automated electromagnetic, eddy-current, flux-leakage and ultrasonic methods (EN ISO 10893 series) for detection of imperfections.
- Manufacturing and materials: Steelmaking processes are at manufacturers’ discretion (fully killed steels required); designation follows EN 10027.
- Ordering and documentation: Mandatory purchaser information (quantity, tube dimensions D x T, steel grade, length, inspection certificate type). Example order format provided (e.g., D 20 x T 2,5 - EN 10305-6 - E235 - standard length - inspection certificate 3.1).
- Packaging, marking and protection: Options for end protection, phosphatization, electrolytic zinc coating, and alternative marking or packaging methods.
- Regulatory note: When referenced under the Pressure Equipment Directive (Directive 2014/68/EU), conformity is presumed only for material technical data; suitability for a specific pressure equipment design must be assessed separately.
Applications and users
- Applications: Hydraulic cylinders, pneumatic actuators, high-precision fluid lines, control systems and other power transmission components requiring tight tolerances and smooth internal surfaces.
- Who uses it: Tube manufacturers, component and system designers, hydraulic/pneumatic equipment manufacturers, procurement/specification engineers, and QA/NDT professionals.
