Particle Analysis (ISO16232/ VDA19)
By : start Category : Technology


Since the anti-blocking system (ABS) came onto the market and diesel direct injection systems became popular mid of the 90’s, technical cleanliness has fully established itself as a quality criterion in the automotive and its supply chains. Damage caused by particles was recognized as a problem since then. The problem had led a growing demand for a standardized method for inspecting particulate contamination. The publication of VDA Volume 19 “Technical cleanliness – Inspection of particle contamination” was released in January 2005. As an international standard, ISO 16232 was developed in 2007 to be equivalent of VDA Volume 19.

The Driven Force

Today there are advanced development in the automotive industry to enhanced performance, lower energy consumption, reduced emissions and improved safety. In order to sustain high quality and properly function, the component suppliers have to manufactured follow stringent cleanliness requirements. To understand current component cleanliness level and measure the improvement, new methods or techniques to assess particulate contamination have been developed.   Not only know where the cleanliness level of components is but also the automotive is driving to ensure components cleanliness is achieved cleanliness specification. Since the year 2000, “technical cleanliness” became a key measure of quality in the automotive and component suppliers.

ALS Solutions

ALS Pathumthani provides technical cleanliness to automotive components in comply with VDA19/ ISO16232. Our solution consists of

1. Extraction contamination by Agitation, Pressure rinsing, Ultrasonic and Functional test bench (small part) in control environment (Class 100 Laminar flow hood.

2. Filter preparation with designated filter 10, 20, 100 up to 200 microns’ pore size.

3. Cleanliness analysis by

    • Mass Gravimetric
    • Automated Sizing and Counting (Metallic, non-Metallic, and Fiber). We are able to distinguish particle size down to 5 microns
    • Nature determining, elemental analysis by SEM/ EDX

4. Report publishing per Component Cleanliness Code (CCC)

5.  And preparing Extraction curve to determine acceptance extraction condition (sample size, setting parameters)
