1.1 This standard describes the minimum performance and operating requirements of mobile non-contact surface contaminant monitoring equipment for paved surfaces providing real-time information. The standard deals with measurement equipment detecting and measuring water-based, weather-produced contaminants such as snow, slush, ice, and standing water on paved surfaces.

1.2 This specification is intended as a minimum performance standard that will be referenced by regulatory organizations and industry participants when determining required compliance to minimum performance requirements when the intended function of the equipment is to supply measurements to be used in determination of safety-critical surface condition assessments. These assessments could include information such as that provided for airport runway condition assessments in the FAA TALPA-ARC framework or in the ICAO Global Reporting Format regulations.

1.3 Mobile non-contact surface contaminant measuring devices are vehicle-mounted measurement equipment that measure and classify the type of weather-produced, water-based contaminant on paved surfaces such as water, frost, slush, snow, and ice. The devices can also detect if the paved surface is free of any of these contaminants. The devices are also able to measure the water-equivalent depth of these contaminants on the surface, which is not the physical depth specified in the ICAO and other regulations used in the aviation industry.

1.4 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
