Full title and description

ISO 16891:2016 — Test methods for evaluating degradation of characteristics of cleanable filter media. This International Standard specifies reference test methods to assess the relative degradation of cleanable (abreinnable) filter media under standardized, simulated gas-exposure conditions, with emphasis on information useful for selection, development and design of industrial bag and cleanable filter systems.

Abstract

ISO 16891:2016 describes a laboratory test protocol to simulate long-term exposure of cleanable filter media (particularly nonwoven fabric filters) to defined gas conditions and to measure relative changes in key properties (for example filtration efficiency, pressure drop and mechanical characteristics). The method is intended to provide comparative data for media selection and design guidance, not to predict absolute in-service performance of full-scale filter installations.

Scope

Provides a standard reference test method to assess the relative degradation characteristics of cleanable filter media for industrial applications when exposed to simulated test-gas conditions over an accelerated or extended period. The procedure focuses on characterizing property changes of media (with particular attention to nonwoven fabric filter media), and is intended to support material selection, media development and bag-filter design decisions rather than to serve as a direct prediction of full-scale filter lifetime or in-service efficiency.

Key topics and requirements

• Definition of simulated gas-exposure conditions and accelerated ageing protocols for cleanable filter media.
• Methods for measuring pre‑ and post‑exposure properties: filtration efficiency, pressure drop, mass change, mechanical strength and structural changes.
• Procedures for applying cleaning cycles (where applicable) and evaluating recovery or further degradation after cleaning.
• Specification of sample preparation, test-rig parameters and reporting requirements to ensure repeatability and comparability.
• Guidance on interpretation: relative degradation indices for media selection rather than absolute service-life prediction.

Typical use and users

Used by filter-media manufacturers, R&D and product development teams, independent test laboratories, baghouse and industrial filtration designers, material suppliers and procurement/specification engineers who need comparative performance data on how cleanable filter media degrade under defined gas exposures and cleaning regimes. Environmental engineers and maintenance teams may use the results to inform operating parameters and maintenance schedules.

Related standards

Related documents and standards commonly referenced with ISO 16891 include other air- and filter-related standards such as the ISO/TC 142 family (national adoptions like EN ISO 16891), standards dealing with particulate filter classification and testing (for example ISO 16890 and ISO 29463 for particulate filtration/HEPA testing), and relevant national/regional test methods and regulatory guidance for industrial air filtration. Users should check applicable national adoptions (e.g., BS EN / DIN EN versions) for adoption-specific changes or translations.

FAQ

Q: What is this standard?

A: ISO 16891:2016 is an International Standard that defines laboratory test methods to evaluate relative degradation of cleanable filter media under simulated gas-exposure conditions.

Q: What does it cover?

A: It covers sample preparation, exposure and cleaning procedures, measurements of key properties before and after exposure (efficiency, pressure drop, mechanical properties, etc.), and reporting to allow comparative assessment of media degradation.

Q: Who typically uses it?

A: Filter manufacturers, materials developers, independent testing laboratories, filtration system designers and specification engineers use it to compare media behaviour and support selection and design decisions.

Q: Is it current or superseded?

A: As published on 15 January 2016, ISO 16891:2016 is a published International Standard. The ISO bibliographic record lists it as the 2016 edition; interested users should consult the ISO catalogue or national standards bodies for any subsequent confirmation, revision or supersession notices.

Q: Is it part of a series?

A: ISO 16891 is a single-part test-method standard addressing degradation of cleanable media; it is related in subject matter to other ISO standards for air filters and filtration testing (for example ISO 16890 and ISO 29463) but is not formally a numbered multipart series.
