Issue date: 2025 01 15

Air intake filter systems for rotary machinery - Test methods - Part 3: Mechanical integrity of filter elements (ISO 29461-3:2024)

This document specifies methods to determine the mechanical integrity of filters under defined conditions that can be encountered in abnormal operating environments. It describes the test methods for filter elements, independent of any ageing procedures like pulsing, loading, temperature cycles, wet conditions or others. The test procedure is intended for filters operating in the range of 0,24 m³/s (850 m³/h) up to 2,36 m³/s (8 500 m³/h). Filter elements with a lower efficiency than ISO T5 (ePM10) according to ISO 29461-1 are excluded. To ensure the comparability of the test results, only new filter elements or those loaded up to 625 Pa or maximum 800 Pa according to ISO 29461-1 are tested. This document does not describe a standardized method to measure the fractional or gravimetric efficiency. The efficiency of the filter element can be tested according to ISO 29461-1. The performance results obtained according to this document cannot be quantitatively applied (by themselves) to predict performance in real use.

Frequently Asked Questions about ÖNORM EN ISO 29461-3

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
