ICEA S 95-658 standard is a document that specifies the materials, constructions, and testing of non-shielded power cables rated 2000 volts or less for use in distribution of electrical energy. It is one of the standards developed by the Insulated Cable Engineers Association (ICEA), a professional organization that represents cable manufacturers and suppliers in North America.

The ICEA S 95-658 standard is updated periodically to reflect changes in technology, industry practices, customer needs and regulatory requirements. The latest edition was published in 2021 with some revisions from the previous edition published in 2014. Some of the changes include new definitions for terms such as “cable core”, “cable element”, “cable system” and “conductor screen”; new tables for conductor sizes; new requirements for insulation thickness; new test methods for water penetration resistance; new annexes for ampacity calculations; among others.

The ICEA S 95-658 standard is widely recognized and referenced by other standards organizations such as ANSI (American National Standards Institute), NEMA (National Electrical Manufacturers Association), UL (Underwriters Laboratories), CSA (Canadian Standards Association) etc. It is also adopted by many utilities, contractors, engineers and end-users who specify or use power cables rated 2000 volts or less.
