Pumping Assembly, Water

** NOTE **: The below questions and answers regarding the Publications and Packaging CDRL portions of the solicitation are posted here for your reference:

Packaging - Attachment 15 Question(s)

1. Section F calls out preserving all exterior unpainted metal surfaces in accordance with MIL-STD-2073 and coating said surfaces with preservative MIL-PRF-16173, Grade 1. In MIL-PRF-53051D, Section 3.10, it states that CARC paint shall not be applied to surfaces greater than 400F which means our metallic exhaust guard would not be painted. Is this coating able to be applied to surfaces greater than 400F? Additionally, is there a reason that preservative MIL-PRF-16173, Grade 1 is not listed in MIL-PRF-53051D anywhere?

2. Is there a MIL, ISO, FDA or some other standard that the corrosion preventative coating for food handling machinery and equipment must meet? Additionally, why is this not a requirement for the Type II - Pump Assembly, Water in MIL-PRF-53051D?

The SPI calls out a preservative that can be used on bare metal when the item is in storage to prevent corrosion. I’m not sure where MIL-PRF-53051D is coming from, it maybe from the PD, which would be engineering and could be focusing on the inside of the pump.

If the contractor wants to use a different preservative on non-metal, it will need to be from MIL-STD-2073, Appendix J and that preservative would need to meet the functionality of MIL-PRF-016173.

3. As far as the packaging preservative goes, these systems are painted with Chemical Agent Resistant Coating (CARC) which has anti-corrosive properties already in it as called out in MIL-PRF-53051D which is the MIL-PRF that these systems are manufactured too. Additionally, they are required based on the solicitation to be delivered in heat treated wooden crates. Is the packaging team stating that the preservative needs to be applied to the wooden crate or the exterior of the unit? The internals of the pump system are already cast aluminum and stainless steel which are inherently corrosion resistant.”

**I’m not seeing where MIL-PRF-53051D was listed in packaging. I reviewed the pkg contract language and CDRLs and didn’t see where it was mentioned. Did the contractor see that in the Purchase Description? If so, that would be an engineering question to answer. **

As far as the wooden crate, it needs to follow heat treatment requirements per DOD 4140.65M and the requirements of the International Standards for Phytosanitary Measures 15 (ISPM), Regulation of Wood Packaging Material as laid out in Section D of the contract.
