    Rationale

    During a November 13, 2019 meeting, the L-60-1 Surveillance Panel discussed the wording of section 8.4.1 in the test procedure. The wording called out Nox-Rust paper as the sole corrosion inhibiting paper supplier for the test. The panel agreed to change the wording to make Nox-Rust a suitable supplier instead of the only supplier. In addition, the requirement of wrapping the gears in a paper towel has been removed since this would act as a barrier between the gear surface and the corrosion inhibiting paper.
