Rubber or plastics hoses and hose assemblies - Hydraulic-pressure impulse test without flexing (ISO 6803:2017)

ISO 6803:2017 describes hose impulse testing, without flexing, of rubber or plastics hydraulic hose assemblies at both high and low impulse pressures. The high-pressure testing is carried out at pressures greater than 3 MPa and the low-pressure testing at pressures from 1,5 MPa to 3 MPa. The test procedure is applicable to hydraulic hose assemblies that are subject to pulsating pressures in service which are included in the product requirements.
NOTE          Impulse test procedures with flexing can be found in ISO 6802.

Gumene ali polimerne cevi ter cevni priključki - Hidravlično tlačno sunkovno preskušanje brez upogibanja (ISO 6803:2017)

Ta dokument opisuje sunkovno preskušanje gumenih ali polimernih hidravličnih cevnih priključkov brez upogibanja
tako pri visokih kot pri nizkih vrednostih sunkov tlaka. Visokotlačno preskušanje se izvaja pri vrednostih tlaka nad 3 MPa, nizkotlačno preskušanje pa pri vrednostih tlaka od 1,5 MPa do 3 MPa. Preskusni postopek se uporablja za hidravlične cevne priključke, ki so pri uporabi izpostavljeni tlačnim sunkom, vključenim v zahtevah za proizvod.
OPOMBA: Postopki sunkovitega preskušanja z upogibanjem so navedeni v standardu ISO 6802.

Overview

EN ISO 6803:2017 - Rubber or plastics hoses and hose assemblies - Hydraulic‑pressure impulse test without flexing (ISO 6803:2017) describes a standardized test method for subjecting rubber or plastic hydraulic hose assemblies to internal pulsating (impulse) pressures without flexing. The procedure covers both high‑pressure (> 3 MPa) and low‑pressure (1.5 MPa to 3 MPa) impulse testing for hose assemblies intended to experience pulsating pressures in service. This edition adds optional cool‑down leakage testing and updates test requirements.

Key topics and technical requirements

• Scope: Impulse testing of complete hose assemblies with fittings attached; applies when product requirements include pulsating pressure exposure. (Impulse with flexing is covered by ISO 6802.)
• Pressure ranges:
  • High pressure: greater than 3 MPa
  • Low pressure: 1.5 MPa to 3 MPa
• Pulse frequency:
  • High‑pressure tests: 0.5 Hz to 1.3 Hz
  • Low‑pressure tests: 0.2 Hz to 1.0 Hz
• Rate of pressure rise and waveform: Pulse waveform must lie within specified envelopes (Figures 2 & 3); pressure recorder or oscilloscope required with natural frequency > 250 Hz and critically damped response.
• Test fluid: Preferably hydraulic fluid with kinematic viscosity ISO VG 32–100 (ISO 3448); circulate to maintain uniform test temperature.
• Test temperature: Usually specified in the referring hose standard; preferred values include 85, 100, 120, 125, 135, 150 °C (±3 °C tolerance).
• Test pieces and geometry: Test four unaged assemblies unless otherwise specified; install hose free length and bend geometry per Figure 1 (≤22 mm ID bent through 180°, >22 mm ID bent through 90°). For d < 25.4 mm, use d = 25.4 mm for the free‑length formula.
• Outcome and reporting: Record number of cycles to failure or cycles completed. Test report must reference ISO 6803:2017 and include hose/fitting details, temperature, pressure, fluid, pulse rate, failure mode, date, etc.
• Notes: This is a destructive test. Leakage below class 4 (ISO/TR 11340) is not a failure. Optional cool‑down leakage test is described in Annex A.

Applications and users

EN ISO 6803:2017 is used by:

• Hose and fitting manufacturers for design validation and production testing
• Independent test laboratories and certification bodies performing hydraulic impulse testing
• OEMs and component specifiers (hydraulic equipment, mobile machinery, industrial systems) requiring validated hose assembly performance under pulsating pressure
• Quality assurance and R&D teams evaluating hose assembly durability and lifetime under cyclic loading

Keywords: EN ISO 6803:2017, hydraulic‑pressure impulse test, hose assemblies, rubber hoses, plastic hoses, pressure cycling, impulse testing, high‑pressure, low‑pressure.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
