C. The pencil shall have a finger grip between the metal point and barrel, at each end of the pencil. Finger grips shall be the color of the lead contained in the point. The finger grips and metal points shall be formed in accordance with standard commercial practice.

D. The mechanical pencil shall operate by twist action to propel the lead from the point and shall operate smoothly and easily, without binding, bending, breaking or other malfunction.

E. Barrels shall be round or polygonal in shape.

F. The point shall grip the lead firmly, without breaking, so that lead does not turn or slip into or out of the pencil. The pencil shall be capable of dispensing the specified lead size.

G. Lead shall not fall free from the pencil such that the lead when reduced to a length of 7 mm shall continue to be retained in the mechanical pencil.

H. The black lead shall be of graphite or synthetic composition. The colored lead shall be of clay or synthetic composition and colors shall be red, blue or other as specified in section VIII. The definitions of terms relating to the manufacture of the carbon and graphite leads shall be in accordance with ASTM C 709.

I. Each pencil shall be furnished with one lead of the appropriate size, color, and composition for each point. The leads shall be 34.5 +/- 2 mm in length.

J. Workmanship. Mechanical pencils shall be securely assembled so that parts do not become loose or displaced and shall be free from defects or imperfections which may adversely affect appearance or serviceability.

II. Performance. A minimum of three leads, of the applicable size, shall be propelled through the mechanical pencil by operating the twist action mechanism, and intermittently performing line drawing and writing actions, without the jamming, falling out, breaking, or failing to feed smoothly. The leads used for this test shall be identical to those supplied with the item.

III. Regulatory requirements. The offerer/contractor is encouraged to use recovered materials in accordance with Public Law 94-580, as amended, to the maximum extent practicable.
