Hi Justin,

It was no definition on ANSI S20.20, but you may define the maintenance plan and frequency of the measurement,

As long as the value of measurement is within spec and it will be no expiry date since someone has a good maintenance and environment condition to extend the life of mat.

Best regards,

Kevin
