ASTM E 3418:2023

1.1 This practice provides procedures for calculating safe and scientifically justifiable limits of residues for use in cleaning validation studies of pharmaceutical/biopharmaceutical/medical device manufacturing equipment surfaces and medical device surfaces. 1.2 The procedures in this standard practice for calculating safe limits of chemical residues are based on Guide E3219 . 1.3 This practice applies to pharmaceuticals (including active pharmaceutical ingredients (APIs); dosage forms; and over-the-counter, veterinary, biologics, and clinical supplies) and medical devices following all manufacturing and cleaning. This practice is also applicable to other health, cosmetics, and consumer products. 1.4 This practice applies to all types of chemical residues (including APIs; intermediates, cleaning agents, processing aids, machining oils, etc.) that could remain on manufacturing equipment surfaces or on medical devices that have undergone all manufacturing steps including cleaning. This practice does not cover extractables and leachables (see ISO 10993-17). 1.5 This practice applies to microbiological residues that may be present on manufacturing equipment surfaces or on medical devices that have undergone all manufacturing steps including cleaning and does not cover disinfection or sterilization. 1.6 Exclusions- Medical devices that do not make patient contact; non-product contact surfaces (which are discussed in other existing guides: Ref ( 1 ) 2 , PDA TR 29, USP <1072>, Guide E2614 , ISO 14698, and ISO 14937). 1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
