4. QUALITY ASSURANCE PROVISIONS

4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use their own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the government. The government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure that supplies and services conform to the prescribed requirements.

4.2 Quality conformance inspection.

4.2.1 Tests and examinations. Perform the content and capacity tests, and examinations of table II. Any defects in the content or capacity tests shall be cause for rejection of the lot. A lot for testing the content and capacity shall be defined as the number of containers filled from the same source during an uninterrupted filling sequence and offered for examination at one time.

Any defects found in the examinations of the containers shall be cause for the rejection of only those defective containers.

TABLE II. Tests and examinations of preparation for delivery.

Test/Examinations Defect Inspection level Content Not as specified in 3.1 One sample per lot, as per 4.2.1 Container Not as specified in 3.2 100% Paint Not as specified in 3.2.1 100% Maintenance Not as specified in 3.3 100% Leakage Not as specified in 3.4 100% Capacity Not as specified in 3.5 One sample per lot, as per 4.2.1 Workmanship Not as specified in 3.6 100% Marking on container Not as specified in 5.1 100% Packaging and packing Not as specified in 5.2 100%

4.3 Test methods.

4.3.1 Sampling. Samples for testing the content and capacity in table II shall be from filled containers and shall be one sample unit per lot.

4.3.2 Hydrogen content determination. Hydrogen content shall be determined in accordance with the analytical procedures specified by CGA G-5.3.

4.3.3 Impurities determination. The sample shall be analyzed for the impurities listed as limiting characteristics in CGA G-5.3 using the analytical procedures specified therein. Unless otherwise specified in the contract or purchase order (see 6.2), these impurities shall not exceed the maximum quantity specified for the appropriate QVL.

4.3.4 Documentation. Records of the analysis and the qualifying concentrations used must be kept on file for two years, and available upon the government's request.

4.3.5 Leakage. Each cylinder, after filling, shall be tested for leakage by applying a soap solution to all portions of the valve, the junction of the valve and cylinder, and the safety device on the cylinder. Care shall be taken to ensure that the solution used does not contaminate the valve outlet. Any evidence of gas leakage, as evidenced by bubbling of the soap solution, shall constitute failure of this test. Failure of this test shall be cause for rejection of the cylinder.

5. PACKAGING

5.1 Marking. The cylinders shall be marked in accordance with 49 CFR 171-185, and as specified in the contract or order (see 6.2). The markings shall not be omitted, incorrect, illegible, or of improper size, location, sequence, or method of application.

5.2 Packaging and packing. The hydrogen of a single grade shall be packaged and packed together in accordance with the contract or order (see 6.2).

6. NOTES

INFORMATION FOR GUIDANCE ONLY. (This section contains information of a general or explanatory nature that is helpful, but is not mandatory.)

6.1 Intended use. Grade A hydrogen is intended for use in general industrial applications such as cutting, welding, and as a lifting medium for meteorological and other balloons. Grade B hydrogen, a higher purity grade, is intended for use in fuel, hydrogenation and water chemistry applications. Grade C is of the highest purity and is use in semiconductor, analytical and special applications.

6.2 Acquisition requirements. Acquisition documents should specify the following:

a. Title, number, and date of this specification.

b. Grade required (see 1.2).

c. Type of cylinder and valve (see 3.2).

d. When supplier is to furnish cylinders (see 3.2).

e. When hydrogen is to be contained in supplier-owned cylinders (see 3.2).

f. When cylinders are to be filled to less than their rated service pressure (see 3.5).

g. Any allowable variance from specified impurity levels (see 4.3.3).

h. Packaging requirements (see 5.1 and 5.2).

6.3 Part or identification number (PIN). The following part or identification number numbering procedure is for government purposes and does not constitute a requirement for the contractor.

BBH886 - X XXXXX

Volume of cylinder 1: 100CF = 100 cubic feet 200CF = 200 cubic feet 300CF = 300 cubic feet

Grade: A = Grade A - 99.95 percent hydrogen B = Grade B - 99.99 percent hydrogen C = Grade C - 99.999 percent hydrogen

Federal specification number

1 The volume of the cylinder may be modified for ease of procurement and is not otherwise limited. The volume codes listed above are not all inclusive and are provided only for example.

6.4 Basis of purchase. The basis of purchase should be the cubic foot, based upon normal atmospheric conditions. Hydrogen is commercially available in cylinders of various rated capacities, with capacities of approximately 200 and 300 cubic feet being common. The quantity in cubic feet for each cylinder size is provided in the characteristics data of the applicable stock number. Normally, hydrogen cylinders will be filled to the following standard conditions: 1800, 2000, 2265, or 2400 pounds per square inch gauge (psig) at 70 �F (21.1 ºC). In cases where the only cylinder available is rated for a higher pressure than requested, Department of Transportation regulations allow for cylinders to be filled to less than the marked service pressure. Also, cylinders specially qualified under 49 CFR to bear the plus (+) mark, have been approved for special filling limits up to 10 percent above the marked service pressure.

6.5 Subject term (key word) listing.

Balloon, meteorological Cutting Cylinder Gas chromatograph Lifting medium

Valve Welding

6.6 Safety considerations. Hydrogen has a very wide flammability range of 4 to 74 percent in air, and burns with an almost invisible flame. The following applies to gaseous hydrogen:

a. Opening a hydrogen cylinder valve to remove dirt or dust may cause self-ignition.

b. Using hydrogen from a cylinder without using a suitable pressure regulator is hazardous.

c. Hydrogen has a very low ignition energy and can be ignited by static electricity.

d. Hydrogen heats when expanded and may self-ignite.

e. By displacing the oxygen in air, hydrogen can act as an asphyxiant.

f. Hydrogen, being very light, may accumulate in high spots if there is inadequate ventilation.

6.7 Changes from previous issue. The margins of this specification are marked with asterisks (or vertical lines) to indicate where changes (additions, modifications, corrections, deletions) from the previous issue were made. This was done as a convenience only, and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations and relationship to the previous issue.
