All phases in the life of the system from initial requirements until retirement including design, specification, programming, testing, installation, operation, and maintenance.
The planned, formal, periodic, and scheduled examination of the status and adequacy of the quality management system in relation to its quality policy and objectives by the organization’s top management.
A set of operations performed for the purpose of determining the value of a quantity
A measurement system is the set of equipment, conditions, people, methods, and other quantifiable factors that combine to determine the success of a measurement process.
Metrology is the science and practice of measurement
Operations that are independent of an established calibration laboratory facility. Mobile operations may include work from an office space, home, vehicle, or the use of a virtual office.
A natural constant is a fundamental value that is accepted by the scientific community as valid.
Formerly known as the National Conference of Standards Laboratories (NCSL). NCSL was formed in 1961 to “promote cooperative efforts for solving the common problems faced by measurement laboratories.
Offset is the difference between a nominal value (for an artifact) or a target value (for a process) and the actual measured value.
Operations that are based in or directly supported by an established calibration laboratory facility, but actually perform the calibration actions at customer locations.
A performance test (or performance verification) is the activity of verifying the performance of an item of measuring and test equipment to provide assurance that the instrument is capable of making correct measurements when it is properly used.
A policy defines and sets out the basic objectives, goals, vision, or general management position on a specific topic
Precision is a property of a measuring system or instrument. Precision is a measure of the repeatability of a measuring system – how much agreement there is within a group of repeated measurements of the same quantity under the same conditions.
Preventive action is something done to prevent the possible future occurrence of a nonconformance, even though such an event has not yet happened.
A procedure describes a specific process for implementing all or a portion of a policy.
The person responsible for the business process.
Determination of laboratory testing performance by means of interlaboratory comparisons.
The quality manual is the document that describes the quality management policy of an organization with respect to a specified conformance standard.
Random error is the result of a single measurement of a value, minus the mean of a large number of measurements of the same value.
Repair is the process of returning an unserviceable or nonconforming item to serviceable condition.
