IEC 61340-5-3:2015 defines the ESD protective packaging properties needed to protect electrostatic discharge sensitive devices (ESDS) through all phases of production, rework/maintenance, transport and storage. Test methods are referenced to evaluate packaging and packaging materials for these product and material properties. Performance limits are provided. This standard does not address protection from electromagnetic interference (EMI), electromagnetic pulsing (EMP) or protection of volatile materials. This edition includes the following significant technical changes with respect to the previous edition: a) removal of all references to ANSI/ESD STM11.13, replaced by normative reference IEC 61340-4-10; b) additional notes added to Table 1; c) addition of a new Table 3 related to the "ESD classification symbol" and the "primary function code".
