4.4 Regulatory Compliance
See the Regulatory Information Appendix (RIA) in the “RoHS compliance” section of www.3Mconnectors.com for
compliance information. See customer drawings for regulatory specifics on each connector.
This document summarizes test methods, test conditions and product performance requirements for the 3M 891XX-0X0X
socket. Listings of materials, finishes, test conditions, and test standards are included in this specification. In the event of
conflict between this specification and any documents listed below, the listed documentation supersedes this specification.
3. Performance and Test Description
Unless otherwise specified, all primary qualification tests shall be performed on 89150-0001 (15µ" Au) sockets, and all current
rating rests shall be performed on 89160-0103 (30µ" Au) sockets. Both sets of tests shall be mated to straight 30µ" gold 3M™
headers and performed using multiple types of 26 and 28 AWG stranded cable at ambient environmental conditions per EIA-
364. Unless otherwise specified, all values and limits are typical of those obtained by qualification testing of the subject
product. All specifications are subject to revision and change without notice from 3M.
