Specifications Relating to Timber Dimension Measuring Devices (SI/2024-48)

Marginal note:Definitions

1 The following definitions apply in these Specifications.

auxiliary equipment

auxiliary equipment means equipment that is connected to, or used in conjunction with, a timber dimension measuring device. (matériel auxiliaire)

default temperature range

default temperature range means, in respect of a timber dimension measuring device, a temperature range of -10°C to +40°C. (plage de températures par défaut)

diameter

diameter means, in respect of a log, its theoretical diameter, in centimetres or metres, calculated by measuring its actual circumference and dividing that value by pi (π). (diamètre)

disturbance

disturbance means a phenomenon or event — such as a short time power reduction or an electrostatic discharge, electrical burst or electromagnetic or electrostatic field — to which a timber dimension measuring device may be exposed and the characteristics of which are inconsistent with the operating parameters of the device. (perturbation)

indicator

indicator means a digital device that is an integral part of, or is connected to, a measuring element and that displays measurement registrations. (indicateur)

influence factor

influence factor means a phenomenon or event to which a timber dimension measuring device or any of its auxiliary equipment may be exposed and that may affect the performance of the device. (facteur d’influence)

interval

interval or d means the value, expressed in units of length, of the difference between two consecutively indicated values for any axis of measurement of a timber dimension measuring device. (échelon ou d)

length

length means, in respect of a log, the maximum distance of a straight line, in centimetres or metres, that

• (a) is measured as closely as possible along the longitudinal axis of the log; and

• (b) is between two planes that are perpendicular to that axis and located at each end of the log. (longueur)

measurement registration

measurement registration means a displayed, printed or recorded representation of the measurement information for a log that has been measured by a timber dimension measuring device, including the dimension measured, the measurement value and the unit of measurement. (enregistrement d’une mesure)

measuring element

measuring element means the parts of a timber dimension measuring device, other than the indicator, that together produce the measurement of a log. (élément mesureur)

metrological function

metrological function means a function of a timber dimension measuring device that is necessary for the measurement process and that may affect measurement registrations or the validity of transactions, including the sensing of the measured object, the transmission, processing, storage, correction or adjustment of measurement signals or values and the display or printing of measurement values. (fonction métrologique)

ready condition

ready condition means, in respect of a timber dimension measuring device, the condition in which it is ready to take a measurement. (état prêt)

timber dimension measuring device

timber dimension measuring device means a measuring machine that measures the length and diameter of logs. (appareil de mesure des dimensions du bois)
