SFI SPEC 38.1 RECERTIFICATION - published: Sep 29, 2011

Dear Sanctioning Body Official:
A recent SFI Specification revision now requires that Head and Neck Restraint Devices which are certified to SFI Specification 38.1 be inspected and recertified every five (5) years, effective January 1, 2012. Any existing certified device with an SFI 38.1 conformance label must be sent back to the original manufacturer for inspection after five (5) years from the date of manufacture punched out on the label. Product inspection, maintenance, and/or replacement procedure will be per individual manufacturer. Inspection must be done by the original manufacturer only, and not their authorized resellers or [COLOR=blue !important][COLOR=blue !important]dealers[/COLOR].[/COLOR]

When a device is determined by the original manufacturer to be acceptable for continued use, that manufacturer will affix a new SFI 38.1 conformance label marked with the inspection date and it will be valid for use for another five (5) years from that date.

Sanctioning Bodies requiring 38.1 devices will begin enforcing the five (5) year recertification rule as of January 1, 2012

Best regards,
