**** NOTICE OF RELEASE OF INFORMATION:

Although not classified, information concerning the award of this contract is considered to be of a sensitive nature. Therefore, release of any information regarding this contract, other than the award date, award dollar value, and contracting office is PROHIBITED without the express written consent of the Contracting Officer.

HEPA Filter Acceptance Testing

a. Production lot acceptance testing will be used to ensure that the produced HEPA filters conform to contract specifications. The Test, Reliability & Evaluation Branch (TREB) is the only facility authorized to perform the lot acceptance testing. The awardee must have a Technology Support Agreement (TSA) set up with TREB so that testing by the government agency can take place.

b. The Contractor shall produce 105% of the requested quantity so that 5% may be submitted for government testing without impacting the final count of delivered filters. The additional 5% of filters produced for testing shall be rounded down to the nearest whole number, but shall never be less than one (1). The filters submitted for acceptance testing will be destroyed after testing.

c. Once the Contractor has produced the lot of HEPA filters, they shall be certified by the Contractor as having met the Government specifications and IEST-RP-CC034 and be given unique serial numbers. The list of serial numbers shall be sent to the COR. The COR will select, at random, the specific filters to be sent for acceptance testing. No additional filters shall be shipped until the government testing results are complete and the lot is found to be acceptable. If the government requests a specific serial number for testing and that specific filter fails contractor testing before it is sent to the government, the entire lot will be considered a failure.

d. Of the filters sent for testing, 10% will undergo rough handling testing per MIL-PRF-232016A prior to the leak testing. For example, if the government orders 8 HEPA filters, the awardee would produce 9 filters. One of the filters would be sent for lot acceptance testing and it would go through rough handling first. If the government orders 300 filters, the awardee would produce 315 filters. Fifteen would be sent for acceptance testing and 2 of the 15 would also undergo rough handling first.

e. The Contractor will receive testing results from TREB and shall provide those results to the COR.

100% of the lot acceptance filters must pass the test in order for the lot to be determined as acceptable. The COR will notify the Contractor if the lot is acceptable and can be shipped or if the lot is unacceptable and shall be destroyed and replaced at no additional cost to the Government.

f. Pre-filters will not be acceptance tested.
