FAQ – Technical cleanliness

What is a particle cleanliness analysis?

Cleanliness analysis refers to the process of assessing and quantifying the level of cleanliness or contamination present on a surface, in a fluid, or within a system. Cleanliness analysis is particularly important in industries where cleanliness standards are critical, such as pharmaceuticals, electronics manufacturing, aerospace, automotive and food processing. Cleanliness analysis involves various techniques and methods. Particle counting is the most common cleanliness analysis technique involving the quantification and characterization of particulate contaminants  present in a fluid thanks to microscopic analysis. Gravimetry is also a cleanliness analysis and involves measuring the weight of contaminants collected on a filter or surface to determine the level of cleanliness. Overall, cleanliness analysis plays a crucial role in ensuring product quality, reliability, and safety accross various industries.

What technical cleanliness matter represents for manufacturer?

Technical cleanliness refers to the degree of cleanliness or the absence of particles in components, systems or fluids within technical applications. Technical cleanliness standards are established to ensure that components and systems meet specific cleanliness requirements to maintain their functionality, reliability, and performance. Contaminants such as particulates can adversely affect the performance and lifespan of mechanical components, electronic circuits, hydraulic systems, and other technical systems. Achieving and maintaining technical cleanliness often involves implementing rigorous cleaning processes, using appropriate cleaning agents and equipment, establishing cleanliness specifications and standards, and implementing quality control measures throughout the manufacturing and assembly processes.

What are the standards and guidelines for technical cleanliness?

Several standards and guidelines address technical cleanliness in various industries, particularly in manufacturing. Some of the most commonly referenced standards include: ISO16232, VDA 19, SAE J1726, NAS 1638, IPC TM-650, ASTM E595…The two technical cleanliness most applied standards in the sector are ISO16232 and VDA19. ISO16232 provides guidelines for the assessment of cleanliness levels on components and systems when VDA19 specifies requirements for technical cleanliness in the automotive industry. Both define methods for sampling, extraction, and analysis of contaminants, including particles and residues. Microvision Instruments solutions comply with all procedures required by technical cleanliness standards

Why is cleanliness analysis important in industrial settings?

Cleanliness analysis is vital in industrial settings for several critical reasons. Cleanliness analysis helps identify and control contaminants (such as dust, grease, and chemical residues) that could compromise the quality and safety of products. This is particularly crucial in industries like pharmaceuticals, food processing, and electronics, where even minor impurities can have significant impacts. Regular cleanliness analysis ensures that the cleanliness standards are constantly met, which is essential for maintaining uniform product quality and meeting customer expectations. Cleanliness analysis also helps ensure compliance with the regulations, avoiding legal issues and fines. Also, regular cleanliness analysis can prevent larger issues that require costly repairs or replacements, thereby saving money in the long run.
