Core processes that may be additional at the ISO 13485 sites include the following as they relate to the Mevopur medical line of products: Change control All changes concerning any Mevopur products are evaluated to determine whether there will be any impact on the product specification or the quality of the product. The category of changes that are evaluated include: raw material, regulatory status, packaging, manufacturing principles, processing equipment, QC methods, manufacturing location, organizational structure, standard operational procedures. Annex 2 – ISO 22000 certifications Avient Colorants Spain S.A, Avient Colorants Santa Clara Coatitla Mexico, and PolyOne Spain SLU have enhanced systems to support food packaging applications with an external ISO 22000 certification adding the following core processes: Change All changes concerning any product produced under ISO 22000 conditions are evaluated to determine whether there will be any impact the Supplier approval and supplier evaluation specification or in the quality of the product. .

To ensure the QMS is aligned with our strategy, and taking into account the internal and external issues, we analyze pertinent information in order to determine potential impact on our context and subsequent customer/organizational success. Are revision changes kept for the life of the active material?

If filling problems exist in thin walled parts, adding flow channels or minor changes in wall thickness can alter the flow. In order to maintain high shear, minimize residence times and promote flow, the passages should have a diameter of 0.250" to 0.375". The efficiency of the design may be verified by recording the time it takes to make a complete color change while producing parts.

Dry colors have also been used but may require more material and time to perform color changes. Organic pigments used to produce yellow, red, blue and green colors are more likely to change color after prolonged residence time or high regrind levels.

MINIMIZING RISK OF CHANGES Incoming batch-to-batch control of ingredients versus a fingerprint to monitor changes, and documented change control beyond CAS number reduce the risk of changes. They are manufactured at ISO 13485 certified sites with bio-compatible raw materials and documented change control.
