STATEMENT OF WORK

High Efficiency Particulate Air (HEPA) and Pre Filters

C.1.0 Scope. The objective of this contract is to obtain HEPA and Pre-filters for use in Chemical Agent Filter Systems (CAFS). The filter systems are considered to be the last line of defense in protecting personnel from potential exposure to chemical agents.

C.3.0. Requirements: The contractor shall follow the Industry Standard (IEST-RP-CC001.5, current version) as outlined in the Filter Requirements section below. Filter acceptance testing will follow the applicable documents and is summarized below in C.3.3.

C.3.1. The Contractor shall provide timely delivery of Government requested material to the address provided below unless otherwise specified by the Government. The government is procuring HEPA and Pre-filters, as outlined in the table below:

C.3.2 HEPA Filter Lot Acceptance Testing. 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.

C.3.2.1 When each new order for HEPA filters is placed, 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.

Part Number Part Description

HEPA-24-11.5 HEPA filter full size

HEPA-12-11.5 HEPA filter half size

Pre-24-6 Pre-filter full size, 6” deep

Pre-12-6 Pre-filter half size, 6” deep

Pre-24-3 Pre-filter full size, 3” deep

Pre-12-3 Pre-filter half size, 3” deep

C.3.2.2 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.

C.3.2.3 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.

C.3.2.4 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.

C.3.2.5 Pre-filters will not be acceptance tested.

C.3.3 Deliveries.

For HEPA Filters: The lot acceptance filters shall be delivered within 120 calendar days of order date. The full order shall be delivered within 15 calendar days of acceptance notification by the COR.

For Pre-Filters: Orders shall be delivered within 120 calendar days of order date.

The hours of operation at the CCDC facility are between the hours of 0800 and 1800 on Monday through Friday.

Delivery of materials shall be within these contract hours. Inspection and Acceptance of the items will be conducted at destination by authorized CCDC government personnel.

C.3.4. Shipping. The cost of shipping the filters shall be the responsibility of the contractor. The filter will be individually wrapped to protect them from the elements and shall be UV stable so as not to break down under prolonged periods of sun exposure. Each filter shall be marked as to what it is and be visible without opening as well as being marked on the adsorber shell on all sides: i.e. Part number, contract number, order number, LOT group number, serial number. The primary delivery location is expected to be:

US Army Receiving 8222 Blackhawk Rd (Bldg E-5179)

APG-EA, MD 21010-5424

C.3.5 Security Considerations. Delivery company must be able to delivery to an on post receiving facility.( The contractor shall not be required to: have access to classified material; to generate classified material; or to store classified material at the contractor’s or government facility or whether access to the RDECOM Local Area Network is required.)

C.3.6 Period of Performance. The total contract ordering period is five (5) years from the effective date of award.

The total ordering period is broken into five (5) individual 12-month ordering periods.
