1.0 SCOPE

1.1 General. This document specifies the minimum requirements for a Magnification Check Kit. This equipment may be of commercial design. 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 traditional optical comparators, both horizontal and vertical configurations. For the purpose of this Calibration Standards Specification (CSS), the Magnification Check Kit herein shall be referred to as the MCK.

1.2 Usage. Equipment covered by this CSS is intended for use in controlled environments in which Military equipment is operated. The requirements of this CSS are tailored to the intended use of the equipment.

1.3 Design activity. This MCK product is specific to Navy calibration requirements.

Maximum use of commercial-off-the-shelf (COTS) items is desired. Should COTS items be unavailable, 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 NAVAIR METCAL Program Office, Team 3.

1.4 Enclosure. For the purpose of this CSS, the enclosure refers to the case for each individual major component. The enclosure provides protection for the individual system components during storage, handling, and use.

1.5 Color. The color of the equipment and the transit cases shall be the color normally provided by the manufacturer but shall not be green, magenta, or red.

1.6 Configuration. The MCK shall have one configuration. The configuration shall allow each component to be replaces if damaged without need to replace the entire kit.
