Historically third party test laboratories have reported a difficulty finding a tape that meets the 40oz requirement. Labs found that Grainger made a paper masking tape that met the requirement. Recently Grainger has discontinued their 40oz tape and the current supply that the labs have is expiring. Labs reported not being able to find another supplier for 40oz tape, however Grainger recommended the closest substitute product to be 45 ounces per 1 inch rated tape, an 12.5% strength requirement increase.

1 inch tape versus 2.5 centimeter tape has a width difference of 0.04cm or a 1.57% increase in width. We determined that this width difference is negligible.

Upon surveying vendors currently on the APEL, none have reported any issues with the update to the tape rating. Most vendors reported testing with a higher rated tape during in-house testing.

PM SPE approves the deviation to MIL-PRF-32432 Rev A until the requirement is updated in MIL-PRF-32432 Rev B to be released September 2021. This allows test labs to accurately test to the new requirement while also providing a more robust requirement.
