DIN is seeking interested parties for a new committee on Technical Cleanliness

Interested parties sought for a new DIN standards committee on technical component cleanliness.

Regarding the topic "Technical Cleanliness of Metallic Components," DIN intends to establish a new committee. Interested operators of parts cleaning systems, responsible personnel for cleaning processes, process chain managers, or users of measurement and testing technology who have a need for a clean surface are invited to participate. Feedback must be submitted by September 30th.

Due to the increasing number of manufacturing processes and end applications, many manufacturers in the industry rely on a clean component surface. The cleanliness of component surfaces (including elastomers and thermoplastics) is therefore an important quality feature, which, despite the use of state-of-the-art production techniques, is not always fully achieved. To ensure that the component has sufficient cleanliness for subsequent manufacturing steps (e.g., assembly, painting) and end applications, existing contaminants must be removed. Contaminants, for example after machining of gray cast iron, stainless steel, or copper-based alloys, include oils and fats, as well as residues of corrosion protection agents, coatings, coolants, and other manufacturing aids. Contributing factors also include preservatives and adhesives, as well as manual welding and fingerprints. Standards can support all these areas. Anyone can participate in standardization work.

Possible standardization topics:

- Terminology
- Occurrence/sources of contaminants and their properties
- Cleaning chemistry
- Available cleaning methods, including application techniques and their limitations
- Recommendations for systematic and quality-appropriate cleaning processes
- Process monitoring (effectiveness and disturbances in the cleaning process, necessary process adjustments, and arising process disruptions)
- Suitable measurement, testing, and analysis methods, including advantages and limitations of various procedures:
- Inspection of component condition along the entire process chain
- Inspection of cleanliness of functional surfaces
- Limits for component cleanliness

Operators of parts cleaning systems, responsible personnel for cleaning processes, process chain managers, or users of measurement and testing technology interested in participating can register with the Material Testing Standards Committee (NMP) of DIN e.V. by September 30, 2020.

The standards committee aims to address the topics "Technical Cleanliness" and the necessary "Cleaning Processes" together and to develop the required standards and norms. DIN is committed to ensuring that those who develop standards are the same as those who later apply them. To ensure market acceptance of the standards, broad participation, transparency, and consensus are fundamental principles at DIN. By participating in standardization, a company can contribute its own interests and gain competitive advantages: active involvement in standardization provides a knowledge edge, allows cost reductions, and enables the pursuit of market expansion strategies.

If interested, feedback is required by September 30, 2020:
