QUESTION AND ANSWER:

The following questions and the Navy's answers are hereby provided. Some of the answers include changes to the solicitation:

Question 1: Is the boat description in the main solicitation document overriding to the NA VSEA specification T9008-CV -SBS-0 1 0?

Answer 1: All references to T9008-CV -SBS-0 10 is hereby deleted. Section C.4.3.3.1 on page eleven is replaced by pages three thru seven of this amendment.

Question 2: Following the recent Navy interpretation regarding DFAR 252.225-7012, please confirm the CRRC inflatable boat is not a textile end product and the boat itself can be built in a qualifying country.

Answer 2: NA VSUP WSS has determined that the CRRC is a textile end product and is subject to the restrictions of DFARS 252.225-7012. A contract may only be awarded to an offeror who offers a product compliant with the clause.

Question 3: On page 8, M-Evaluation- Note (2) seam Samples refers to paragraphs C.6.1 & C.6.2 which are not contained in the solicitation. Please clarify.

a. The test shall be carried out not less than 16 hours after curing.

b. Disk specimen for testing shall be at least 70 millimeters in diameter. A typical apparatus required is shown in figure 5. It consists of a base-plate (A) and an open-ended cylindrical chamber (B) which is held tightly against the test specimen (C) by wing nut (D), the wing nuts are mounted on bolts (E). A hole of diameter approximately 30 millimeters shall be made in the base plate for the examination of the surface not in contact with the liquid. During the test the opening in the top of the chamber is closed by a close fitting plug (P).

c. Test specimens in the "As Received" condition shall be conditioned for not less than three hours at 20 ±2°C immediately before testing.

d. The test specimens shall be placed in the apparatus as indicated in figure 1. The chamber of the apparatus is then filled with the test liquid to a depth of approximately 20 millimeters and the plug (P) inserted. The required temperature and the duration shall be 20 ±2°C for 22 hours.

e. At the end of the contact period the test liquid is removed and the test specimen released. Any surplus liquid is removed from the surface of the test specimen by blotting with filter paper or a textile fabric which does not deposit lint.

f. The test specimen shall be folded over so that the surfaces are pressed together to see if there are any signs of residual tackiness.

g. With the test specimen opened out, a single pass of the finger over the exposed surface shall not produce smearing.

h. The liquid to be used as a standard test oil shall be ASTM #1 Oil.

C.4.3.3.1.1.11 Resistance To Low Temperature. The coating shall be visually examined for signs of cracking or flaking when tested in accordance with the following method. The coated fabric shall be tested at -sooc per Method 5874 of FED-STD-191 with the exception that the hydrostatic resistance portion of the test is not required.

Place two coated fabric specimens 150 millimeters by 25 millimeters in an oven on a smooth surface in such a manner that the ends are overlapped 25 millimeters. Place a 2.7 kilogram weight directly on the overlapped area. After conditioning at a temperature of 70 ±2°C for 4 hours, remove the weight and take the specimens from the oven and condition for 1 hour at 23 ±1 °C.
