3.2 Manufacturing and Process Requirements

3.2.1 Mercury Contamination

The nitrogen shall not contain and shall not be contaminated by mercury or mercury compounds. During the manufacturing process, tests and inspections, the product shall not have come in direct contact with mercury, nor any of its compounds, nor any mercury containing device employing a single boundary of containment.

3.2.2 Foreign Material Exclusion

The nitrogen shall be free from foreign material such as oil, grease, dirt and debris.

Production operations shall be conducted so as to assure the required level of cleanliness. Such operations may include but are not limited to the following precautions: Ensuring that the nitrogen containers are free from foreign material prior to fill, providing an area for fill operations that is free of dirt and debris, and maintaining the fill equipment in a clean condition.

3.2.3 Container Requirements

New cylinders shall conform to the requirements of FED-RR-C-901. Used or Government furnished cylinders shall conform to the requirements of MIL-STD-1411 and 49 CFR 100-199 prior to refilling. Cylinders are to be color coded according to MIL-STD-101. Type II liquid nitrogen shall be contained in either supplier owned or Government owned insulated containers in accordance with 49 CFR 171-190.

- 3 -

3.2.4 Valve Requirements

Cylinder valves shall conform to the requirements of MIL-DTL-2, Valve Outlet Application 580 for cylinders with rated pressures less than 3000 psig and Application 680 for cylinders with rated pressures greater than 3000 psig.

3.2.5. Lot Size Requirements

A lot is defined as all nitrogen produced during a consecutive 24-hour period from the same source, by one manufacturer, at one plant, from the same materials, and under essentially the same manufacturing conditions provided the operation is continuous. A source is considered to be either an individual nitrogen producing process or an individual storage container to which no nitrogen is added after the initial filling.

In the event the process is a batch operation, each batch (see 3.2.6 below) shall constitute a lot. Even if a batch is larger, each lot of Type I nitrogen cylinders ready for delivery shall be limited to a maximum of 500 cylinders. For Type II liquid nitrogen, each individually filled container shall be considered a lot.

3.2.6 Batch Requirement

That quantity of material which has been manufactured by some unit chemical process.

3.2.7 Processing Requirements

Type I gaseous nitrogen shall be manufactured by any process known not to introduce oil into the nitrogen. Type I gaseous nitrogen shall be compressed with a water-lubricated or dry-seal compressor or produced using a cryogenic converter from a liquid nitrogen source. Cylinders shall be filled using a 10-micron or better filter, positioned at or close to the cylinder charging manifold, that is capable of removing both oil and solid particulates.

The settled pressure in a filled container shall be within 25 psig of the pressure that corresponds to the settled container temperature as shown on Table 2.

4.0. QUALITY ASSURANCE PROVISIONS

4.1 Inspection System Requirements

The vendor shall maintain complete records for all inspections and tests performed on the product. The records shall be traceable by the vendor's lot or batch number. These records shall indicate the nature and number of observations made, the number and type of deficiencies found, the quantities approved and rejected, and the specific actions taken to correct the deficiencies.

- 4 -

4.2 Test Equipment Requirements

All gages, measuring and test equipment used in the tests, inspection and processing of the product shall be calibrated to certified standards that have known, valid relationships to nationally accepted industry standards. The calibration frequency for each device shall be based on its stability, purpose and usage. A positive means (such as stickers) shall be provided to identify the calibration interval, last date of calibration and date calibration is due for each device. Complete written records of calibration data traceable to the individual test devices shall be available for Contracting Agency review.

4.3 Contract Certification Requirements

The contractor shall certify and maintain substantiating evidence that the product offered meets the salient characteristics of this Commercial Item Description in accordance with the required frequency of testing specified in Section 3.2.5 and that the product conforms to the producer’s own drawings, specifications, standards, and quality assurance practices, and is the same product offered for sale in the commercial marketplace. The Government reserves the right to require proof of such conformance prior to first delivery and thereafter as may be provided for under the provisions of the contract.

4.4 Inspection Requirements

Sampling for visual inspection of Type I containers shall be performed on those containers that are ready for delivery. Samples shall be chosen randomly and in accordance with Table 1.

Type I containers should be sampled from near the beginning and end of the production run, and if more than two containers are required, from points in between. Type II containers shall be visually inspected individually.

Table 1

Sampling Requirements For Type I Containers

Lot Size Number of Containers

≤ 25 2

26 to 150 3

151 to 500 5

Each selected container shall be inspected for conformance with the requirements specified in Section 3.2.3 (Container Requirements), Section 3.2.4 (Valve Requirements), Section 5.0 (Shipping Requirements) and Section 6.0 (Marking Requirements) of this description. Failure of any one container constitutes failure of the entire lot. A failed lot may be resubmitted for inspection provided the vendor has corrected all the non-conforming attributes.

- 5 -

4.5 Testing Requirements

Sampling for testing of a lot of Type I gaseous nitrogen shall be from containers that are ready for delivery in accordance with the requirements specified in Section 4.4 of this specification.

Sampling for testing of a container of Type II liquid nitrogen shall be in accordance with ASTM F 310. Before any test is performed, sufficient nitrogen shall be permitted to flow to displace any other gas present in the test equipment lines. Liquid nitrogen shall be in the vapor form when tested. The following tests shall be performed on each sample selected for testing per the designated procedure. Acceptance criteria are as specified:

Characteristic Test Method Acceptance Limit

Purity CGA G-10.1 Grade A 99.95 % Minimum by Volume Grade B 99.50 % Minimum by Volume

Oxygen Content CGA G-10.1 Grade A 0.05 % Maximum by Volume Grade B 0.50 % Maximum by Volume

Odor CGA G-10.1 None Detectable Hydrocarbon Content CGA G-10.1 <50 ppm as Methane by Volume Leakage (Type I Only) MIL-STD-1411 None

* Note: The 0.02 milligram water per liter of gas is equivalent to 26.3 ppm water vapor by volume and also to a dewpoint of minus 63.5 degrees Fahrenheit.

5.0 SHIPPING REQUIREMENTS

The shipment of nitrogen containers shall be in accordance with 49 CFR 171-190. Containers shall conform to the Uniform Freight Classification, National Classification Board or regulations of other carriers as applicable to the mode of transportation. Palletization of containers shall be in accordance with MIL-HDBK-774.

A Material Safety Data Sheet (MSDS) prepared per FED-STD-313 shall be provided with each pallet and affixed/packaged in a manner for easy accessibility without being lost or damaged during shipment and storage. In accordance with 29 CFR 1910.1200, one copy of the MSDS shall be provided with the bill of lading for each shipment of material.

6.0 MARKING REQUIREMENTS
