SECTION SF 30 - BLOCK 14 CONTINUATION PAGE

The following have been added by full text:

AMENDMENT 2

The purpose of this amendment is as follows:

Solicitation Revisions:

1. The solicitation closing due date and time has been extended to 2pm CT on June 25, 2018 (Monday).

Specification Revisions:

2. SECTION 35 20 14 paragraph 2.1.2.1 General Requirements is revised as follows:

From:

Rubber seals shall be fluorocarbon (Teflon) clad rubber seals of the mold type only, shall be compounded of natural rubber, synthetic polyisoprene, or a blend of both, and shall contain reinforcing carbon black, zinc oxide, accelerators, antioxidants, vulcanizing agents, and plasticizers. Physical characteristics of the seals shall meet the following requirements:

To:

Rubber seals shall be of the mold type only, shall be compounded of natural rubber, synthetic polyisoprene, or a blend of both, and shall contain reinforcing carbon black, zinc oxide, accelerators, antioxidants, vulcanizing agents, and plasticizers. Physical characteristics of the seals shall meet the following requirements:

3. SECTION 35 20 14 paragraph 2.1.2.2 Fabrication is revised as follows:

Rubber seals shall have a fluorocarbon film vulcanized and bonded to the sealing surface of the bulb. The film shall be 0.030 inch thick Huntington Abrasion Resistant Fluorocarbon Film No. 4508, or approved equal, and shall have the following physical properties:

Tensile strength 2,000 psi (min.)

Elongation 250 percent (min.)

The outside surface of the bonded film shall be flush with the surface of the rubber seal and shall be free of adhering or bonded rubber. Strips and corner seals shall be molded in lengths suitable for obtaining the finish lengths shown and with sufficient excess length to provide test specimens for testing the adequacy of the adhesion bond between the film and bulb of the seal. At one end of each strip or corner seal to be tested, the fluorocarbon film shall be masked during bonding to prevent a bond for a length sufficient to hold the film securely during testing.

Not used. (deleted paragraph)

4. SECTION 35 20 14 paragraph 2.4.2 Rubber Seals Test Requirements is revised as follows:

W912ES18B0005

The fluorocarbon film of rubber seals shall be tested for adhesion bond in accordance with ASTM D413 using either the machine method or the deadweight method. A 1 inch long piece of seal shall be cut from the end of the seal which has been masked and subjected to tension at an angle approximately 90 degrees to the rubber surface. There shall be no separation between the fluorocarbon film and the rubber when subjected to the following loads:

THICKNESS OF

FLUOROCARBON FILM

MACHINE METHOD AT 2

INCHES PER MINUTE

DEADWEIGHT METHOD

0.030 inch 30 pounds per inch width 30 pounds per inch width

0.060 inch 30 pounds per inch width 30 pounds per inch width

Failure of any specimen to meet the requirements of the test used will be cause for rejection of the piece from which the test specimen was taken.

Not used. (deleted paragraph)

Drawing Revisions:

5. Revised the bulb to 1 ¾ inch diameter and the tail thickness to 9/16 inch details on drawings: C1/S-301, C1/S302, C1/S-501, A1/S-501, C3/S-501, C1/S-502 and A1/S-502.

6. The Government revised the design such that the backer bar is welded to the skin plate, not to the retainer bar, and the bearing seal is notched to clear the weld. See amended drawing C3/S-502 and detail A3/S-502.

The revised drawings are attached in half size and full size versions.

All other terms and conditions remain unchanged.
