It is intended to be used by Navy personnel in shore-based laboratories and for on-site, in-place calibration. The equipment will be used to calibrate TIs such as the Schwien precision manometer, granite surface plates, and dial indicator calibrators. For the purpose of this calibration standards specification (CSS), the XL-80 Laser System or equivalent shall be referred to as the Laser System.

1.2 Usage. Equipment covered by this CSS is intended for use in testing equipment and systems in the worldwide natural and controlled environments in which Military equipment is operated. Equipment will also be subjected to operational conditions aboard land, sea and air vehicles, both military and commercial during periods of operation, transportation and storage. The requirements of this CSS are tailored to the intended use of the equipment. Specific requirements of MIL- PRF-28800G, as identified in this CSS, are invoked according to the class of equipment.

1.3 Design activity. This Laser System product is specific to Navy calibration requirements. Maximum use of commercial-off-the-shelf items is desired. The overall product design, packaging, and life-cycle configuration management is under the cognizance of the Navy. The Cognizant Design Activity (CDA) for documentation and configuration management shall be the Naval Surface Warfare Center - Corona Division, Measurement Science and Engineering Department, Metrology Drawing (MET-D) Coordinator.

1.4 Classification. Equipment specified herein is categorized by class, (requirements arising from the intended operational environment). The class is assigned by the most severe environmental condition expected for the equipment. Selected environmental requirements have been derated herein from the most severe environmental requirements specified for the class in MIL-PRF-28800G. The equipment shall conform to the following class requirements in accordance with MIL-PRF-28800G for Navy shore-based laboratory use as specified in this CSS.

a. Class 3 – Equipment is designed for operational environments where conditions are routinely encountered in a diverse, controlled climate.

Examples include test equipment for bench-top, rack-mount, or occasional portable use in diverse and environmentally controlled locations.

b. Class 4 – Equipment is designed for benign operational environments where the environmental conditions are controlled and protected. Examples include test equipment for use in a fully protected and environmentally controlled service area such as a laboratory.
