MIL-PRF-5480 Data, Engineering And Technical: ReproductionThis specification covers the requirements for the production, preparation for delivery, and shipment of non-digital reproducible and nonreproducible reproductions of drawings, associated lists, and related engineering and technical data. The original documents from which these reproductions are produced may be manually or computer generated and are not addressed by this specification. For the purposes of this specification, the direct output from a digital source is considered the original from which non-digital reproductions meeting the requirements herein are produced.

3.2 Detail Requirements.

3.2.1 Legibility and contrast. Legibility and contrast of reproductions shall be such that

every line, number, letter, and character is clearly legible and readable.

3.2.2 Reproductive quality. Class 2 and 3 reproductions shall be of such clarity as to

produce fourth generation reproducibles (see 6.3.2) which will meet the legibility requirements

specified herein.

3.2.2.1 Class 3. Reproductions shall be of high-contrast, transparent or translucent

material, having allowable tolerance and stability characteristics within the following limits.

a. Stability. Changes in linear dimensions shall not exceed 0.00001 inch per inch

(0.00001mm per mm) per degree Fahrenheit (.6 degree Celsius) when the material, conditioned at

80 degrees Fahrenheit (26.7 degrees Celsius), is exposed to 220 degrees Fahrenheit (104 degrees

Celsius) for one hour and returned to the original condition temperature. Changes in linear

dimensions shall not exceed 0.00001 inch per inch (0.00001mm per mm) per percent relative

humidity when the material, conditioned at 10% relative humidity, is exposed to 98% relative

humidity for twenty four hours and returned to the original conditioning relative humidity.

b. Allowable tolerance. The thermal and hygroscopic coefficients of linear expansion

shall be such that the allowable overall tolerance between check points at extremities of the sheet

(length or width direction) shall not exceed+0.015 inch (in 144 inches) or+0.38mm (in

3650mm) when exposed to a 7 degree Fahrenheit or 3.8 degree Celsius rise or drop in

temperature, or a 7% rise or drop in relative humidity under normal room conditions.

Reproducibles shall be marked in the right-hand corner, adjacent to or above the title block, per

the example shown in figure 1, and the atmospheric conditions shall be recorded at the time of

reproduction.

c. Care and Handling. In order to maintain the stability requirements defined above,

reproducibles shall be rolled to a minimum diameter of 3 inches (76mm).

d. Clarity. Lettering and linework shall be clear, legible, and suitable for reproduction.

3.3 Nonreproducible reproductions.Class 1 reproductions shall be direct reading and

shall conform to 3.2.1.

3.4 Reproducible reproductions.Class 2 and 3 reproductions shall be direct reading

and shall conform to 3.2.1. They shall be prepared on translucent or transparent material and

permit a minimum of 150 acceptable direct reading reproductions to be made from them. These

reproductions shall be capable of being reproduced on continuous reproduction equipment
