ISO/TS 19713-1:2010

Overview

ISO/TS 19713-1:2010 specifies laboratory fractional efficiency testing methods for engine air cleaners and air filter elements used in road-vehicle and compressor inlet systems. The technical specification covers measurement of filter performance for fine particles (0.3 µm to 5 µm optical diameter) and defines uniform procedures, equipment characteristics, test conditions and report formats so that filter performances can be reliably compared on a laboratory test stand.

Key measurable performance parameters include:

• Fractional efficiency by particle size (initial and during loading)
• Pressure loss / airflow restriction
• Test dust loading and incremental efficiency at specified fractions of filter life

Key topics and technical requirements

ISO/TS 19713-1 focuses on reproducible laboratory assessment and includes requirements and methods for:

• Test principle and sequence - how to conduct fractional efficiency and loading tests.
• Test equipment, accuracy and validation - specification of particle measurement devices (recommended: optical particle counters, OPC), calibration, and validation procedures.
• Test aerosols - definitions for low-concentration efficiency challenge aerosols (neutralized to approximate Boltzmann charge distributions) and higher-concentration loading aerosols.
• Measurement metrics - fractional efficiency, fractional penetration, correlation ratio (upstream/downstream alignment when no filter is present), pressure loss, and test airflow rate.
• Loading protocol - procedures to load filters with standard test dust (ISO 12103-1 Arizona test dust) and measure incremental efficiencies at 10 %, 25 %, 50 % and 100 % of defined filter life based on pressure loss.
• Data processing and acceptance - calculations, Poisson statistics and data reduction methods (detailed in normative annexes).
• Report format - standardized reporting to enable direct comparison between filters (informative Annex A).

Applications and users

ISO/TS 19713-1 is intended for:

• Filter and air cleaner manufacturers validating performance of filter designs
• OEMs (engine and vehicle manufacturers) specifying inlet air cleaner requirements
• Independent testing laboratories performing comparative efficiency and loading tests
• Research organizations and regulators studying airborne particulate protection for engines and compressors

Typical practical uses: product development, quality control, supplier validation, procurement specifications, and demonstrating compliance with performance requirements.
