Test of efficiency by particle size and total efficiency – Influences of test parameters and measuring technology

M. Schmidt*, PALAS GmbH, Germany

Conference Session: G02 - Filter Test Systems - 2023-02-14 - 14:45

The difference in efficiency results in filter and filter media testing is often based on the difference in measuring technology. Scattered light particle sizers or SMPS systems usually used in fractional efficiency testing vs. the integral efficiency obtained by a scattered light photometer.

Various standards define different test instrumentation to measure the efficiency of various filters and filter materials for different applications.

Commonly used is either the efficiency by particle size as e.g.by ISO 11155-1 and DIN EN 71460 -1+3 in Cabin air filtration, ISO 29463 in HEPA/ULPA filtration, ISO 16890 in general ventilation filtration testing, or the integral efficiency with a defined test aerosol as by EN 149, EN 143, 42 CFR 84, and GB 2626 in mask testing, DIN EN/IEC 60335-2-69 A.3/AA.22.201.2 or DIN IEC 60312 in vacuum cleaner filter testing.

In the PMFT Series by Palas® the aerosol spectrometer Promo® was successfully integrated to measure integral efficiency with comparable results to the photometer as described in the mask testing standards. Based on the measurement of efficiency by particle size, the system can adjust the particle size distribution to the requirements of the different standards. This is necessary to get comparable results with the photometer method.

Additional advantage by using the particle counting device is for sure to obtain efficiency by particle size also. The system can be adjusted to different test conditions concerning particle concentration and air flow of filter media testing according to the standards for cabin air filters, general ventilation filters and to some extend even HEPA filters.

This presentation outlines the technical background to convert the data from the Promo® Aerosol spectrometer in comparable results with photometer-based measurements. The results from round robin tests for face masks in Europe and United States prove...

It`s a long way to clean air - If you wanna have zero emission cars

S. Schütz*, M. Schmidt, PALAS GmbH, Germany

Conference Session: G14 - Automotive Applications I - 2023-02-16 - 13:00

Zero emission cars are one key to reach cleaner environment. However up to now it`s still a long way to reach that goal.

In the past the standards like the ISO 5011/ ISO TS 19713 for Engine Intake Filter to protect the engine and it`s performance, ISO 17536 for Crank Case Ventilation Filter to reduce the aerosol emissions, were very common in the automotive application, as well as the ISO 11155 Cabin Air Filtration for the protection of the passengers.

The Particle Measurement Programme or PMP is a programme for advancing the particle measurement technique for particulate vehicle exhaust gases. This was seen up to now the main driving for the car emissions, which lead us to the DPF filters in the automotive section. Recently the PMP test equipment shift their cut off size from 23 nm down to 10 nm.

In the automotive area there are several approaches in the past as well as upcoming guidelines to reach a zero-emission car.

Some approaches and research are nowadays done on the tyre abrasion, as well as on the brake emissions. The goal is to get a full footprint of the car emissions. The problem in that case is the output of fine dust as well as microplastic caused by abrasion of tyres and brakes. With the upcoming EU 7 standard the brake emission guideline GTR Proposal on Laboratory Measurement of Brake Emissions for Light-Duty Vehicles is on the way. Within the GTR Proposal the particle number counts as well as the PM 2.5 and PM 10 values are now in the focus. The solution is a brake dust emission filter which lead us closer to a zero-emission car and cleaner air.

Some zero emission cars are even available on horizon, like Prototype Zero Emission Drive Unit – Generation 1, the ZEDU-1. This car was developed by DLR (Deutsche Zentrum für Luft- und Raumfahrt) and the automotive company HWA. The ZEDU-1 was first introduced to public on the 28th of September 2022 on the Karlsplatz in Stuttgart, Germany.

There is still a long way to go until zero emission cars will be something normal. We like to show in this paper some solutions and measurement concepts to reach that goal...
