Описание (английский):

ISO 2941:2009 specifies a method for verifying the collapse/burst pressure rating of a hydraulic fluid power filter element, i.e. the capability of a filter element to withstand a designated differential pressure at the normal (i.e., intended direction of) flow, by means of pumping contaminated fluid through the filter element until either collapse/burst occurs or the maximum expected differential pressure is reached without element failure.

Overview

ISO 2941:2009 - "Hydraulic fluid power - Filter elements - Verification of collapse/burst pressure rating" specifies a standardized test method to verify a hydraulic filter element’s ability to withstand a designated differential pressure in the intended flow direction. The procedure pumps a contaminated fluid through the element until either structural collapse/burst occurs or the target differential pressure is reached without failure. The standard is used to confirm the structural integrity and collapse/burst pressure rating of filter elements in hydraulic fluid power systems.

Key topics and requirements

Test objective: Verify collapse/burst pressure rating of a filter element under realistic contamination loading.

Test circuit and apparatus: Typical components include a test filter housing, pump and motor (maintain constant flow ±5%), reservoir designed to keep contaminants in suspension, connectors/valves, differential pressure transducer, flowmeter and an electronic strip chart recorder or data logger (recommended response 40–100 Hz; Annex A suggests >50 Hz).

Fluid and contaminant: Use a fluid compatible with filter materials per ISO 2943; contaminants are inert particulates such as ISO 12103‑1 A2 (Fine) or A3 (Medium) test dust. Contaminant must not strengthen the element.

Test procedure essentials:

Pre-check fabrication integrity per ISO 2942 (first bubble point).
Determine test flow rate (manufacturer’s nominal or 50–80% of nominal) and temperature (15–40 °C unless specified).
Inject contaminant continuously or intermittently at ≤5% of estimated contaminant capacity per injection interval (preload of 50% capacity allowed by agreement).
Record differential pressure versus contaminant mass added until collapse or target pressure is reached.

Acceptance criteria:

No visual failure after ISO 2942 integrity test, and
No abrupt decrease in the slope of the differential pressure vs. contaminant mass curve prior to the rated collapse/burst pressure (see Annex C).

Reporting: Required data include test flow rate, maximum differential pressure achieved, fluid type/viscosity/temperature, contaminant type, flow direction, and minimum collapse/burst rating (Annex B provides a report form).

Applications and users

Filter manufacturers validating product structural ratings for catalogues and certifications.

Test laboratories performing hydraulic filter qualification and performance verification.

OEMs and component specifiers requiring verified collapse/burst ratings for hydraulic system safety and reliability.

R&D and quality assurance teams assessing element design robustness under contamination loading.
