2.3 Non-Government publications. The following documents form a part of this document to the extent

specified herein. Unless otherwise specified, the issues of these documents are those cited in the solicitation or

contract.

ASTM INTERNATIONAL

Equipment, and Facilities

(Copies of this document are available from ASTM International online at www.astm.org.)

2.4 Order of precedence. Unless otherwise noted herein or in the contract, in the event of a conflict between

the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this

document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained.

3. REQUIREMENTS

3.1 Qualification. QAWTDs furnished under this specification shall be products that are authorized by the

qualifying activity for listing on the applicable qualified products list before contract award (see 4.2 and 6.3).

3.2 Materials. Material selected shall meet the requirements specified herein. QAWTDs and associated parts

shall be constructed of materials that meet the requirements specified herein with regard to corrosion resistance,

relative stiffness between the bulkhead and the QAWTD, and interchangeability with current Navy assets. In order

to ensure interchangeability, pins, fasteners, actuating mechanisms, and other hardware shall be manufactured from

CRES 316, if strength requirements permit. Antiseize compound in accordance with A-A-59313 shall be applied to

all threaded fasteners and in way of static, closely fitted pieces subject to galling or crevice corrosion (for example,

between dogs and spindles) where grease is not specified. The use of carcinogenic materials is prohibited.

3.3 Recycled, recovered, environmentally preferable, or biobased materials. Recycled, recovered,

environmentally preferable, or biobased materials should be used to the maximum extent possible, provided that the

material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous

life cycle costs.

3.4 Design. The QAWTD shall be constructed with the ability to support clear opening sizes and hydrostatic

tightness pressures listed in table I. Components of the QAWTD shall be contained within the footprint of the

QAWTD frame. (see 1.2)

3.4.1 Actuating mechanisms. Actuating mechanisms shall be designed to avoid metal-to-metal contact on any

actuating or rotating device. Actuating mechanisms shall also be designed to avoid the need for lubrication.
