Type I log camels shall be treated as specified (see 3.7.1 and 6.2), and type II shall be untreated. When specified (see 6.2 and 6.7), the logs shall be lathe turned to a uniform nominal diameter along the entire length of the log.

Unless otherwise specified herein, all equipment, material, and articles incorporated in the work covered by this specification are to be new and fabricated using materials produced from recovered materials to the maximum extent possible without jeopardizing the intended use. The term “recovered materials” means materials which have been collected or recovered from solid waste and reprocessed to become a source of raw materials, as opposed to virgin raw materials.

Unless otherwise specified, none of the above shall be interpreted to mean that the use of used or rebuilt products is allowed under this specification.

3.3.1 Wood for log camels. Logs selected for treatment shall have sufficient sapwood thickness to ensure the required penetration and retention are achieved (see 3.6).

Logs used for camels shall conform to ASTM D 25, except as modified by this specification.

3.3.1.1 Species. Treated (type I) log camels shall be of either Coastal Douglas Fir or Southern Pine. Alternative species used for untreated (type II) log camels shall retain their shape, have adequate buoyancy (see 3.3. 1.5), and have fiber strength and density similar to the treated, type I camel log species.

3.3.1,2 Scars. Logs may have sound turpentine scars which are undamaged by insects. No scars shall be greater than 3 feet (914 mm) in length.

4. VERIFICATION

4.1 Classification of inspection. The inspection requirements specified herein are classified as follows:

a. First article inspection (see 4.2).

b. Conformance inspection (see 4.3).

4.2 First article inspection. The first article inspection shall be performed on one complete camel log when a first article is required (see 3.2 and 6.2). This inspection shall include the examinations of 4.4 and the test of 4.5. The first article may be either a first production item or a standard production item from the supplier’s current inventory provided the item meets the requirements of the specification and is representative of the design, construction, and manufacturing technique applicable to the remaining items to be furnished under the contract.

4.3 Conformance inspection. The quality conformance inspection shall include the examinations of 4.4 and the buoyancy test of 4.5. Unless otherwise specified (see 6.2), the inspection will be performed at the point of production.

4.4 Examination. Each log camel shall be examined for compliance with the requirements in section 3 of this specification. This element of inspection shall encompass all visual examinations, dimensional measurements, review of certificates of inspection, and check for the approved agency quality mark. Any log camel having one or more defects shall be cause for rejection of that camel,

4.4.1 Examination before treatment. Type I log camels shall be examined for compliance with the requirements of 3.3 through 3.5.1, within 10 days prior to treatment.

4.4.2 Examination after treatment. After preservative treatment, and installation of hawse pipes if required, type I log camels shall be examined for compliance with 3.6 through 3.9.1.

4.5 Buovancv test. Prior to treatment, each log shall be placed in water and allowed to float freely. The log shall conform to the buoyancy requirements of 3.3.1.5,

5. PACKAGING

5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD personnel, these personnel need to contact the responsible packaging activity to ascertain requisite packaging requirements. Packaging requirements are maintained by the Inventory Control Point’s packaging activity within the Military Department or Defense Agency, or within the Military Department’s System Command. Packaging data retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.

6. NOTES

(This section contains information of a general or explanatory nature which is helpful, but is not mandatory.)

6.1 Intended use. Log camels are intended for use as a floating device to breast out a vessel from a pier or mooring, or to separate two vessels to provide protection to the vessels and minimize damage to pier pilings. The log camels covered in this specification are for fresh water or sea water use.

6.1.1 Twe L class 1. Type I, class 1 log camels are for use in marine waters in those areas of moderate borer hazard where Iimnoria tripunctata attack is limited or not expected (primarily in northern latitudes but with exceptions in both northern and southern latitudes).

6.1.2 Type I, class 2. Type I, class 2 log camels are for use in marine waters in those areas of severe borer hazard where limnoria tripunctata attack is known or expected and where pholad attack is absent.

6,1,3 TvPe I, class 3. Type I, class 3 log camels are for use in marine waters in those areas of severe borer hazard where Iimnoria tripunctata and pholad attack is known or expected.

6.1.4 Tvpe II. Type H, untreated log camels are for use in fresh water, where there is no marine borer hazard.
