3.1 General definitions

3.1.1

durability

ability of a measuring instrument to maintain its performance characteristics over a period of use

[SOURCE: OIML V 1:2013, 5.15 ^[1] ]

3.1.2

3.1.3

load cell

measuring transducer that will produce an output in response to an applied load. This output may be converted by another device into measurement units such as mass

3.1.3.1

analogue-passive load cell

load cell from which the output provides either measurable data or direct information representing the measurand value

3.1.3.2

analogue-active load cell

load cell which is capable of performing the functions as described under analogue-passive load cell (3.1.3.1) and which also utilises active electronics

3.1.3.3

digital load cell

analogue-active load cell which includes an analogue to digital conversion device providing a representation of the measurand value in some unprocessed digital format

3.1.3.4

digital load cell equipped with further data processing (Figure 2, A-F)

analogue-active load cell which includes an analogue to digital conversion device providing a representation of the measurand value in some digital format and includes further digital processing (e.g. scaling)

3.1.4

marking

affixing of one or more marks

(For notes, refer to the OIML V 1:2013).

3.1.5

metrological supervision

activity of legal metrological control to check the observance of metrology laws and regulations

(For notes, refer to the OIML V 1:2013).

3.1.6

measuring transducer

device, used in measurement, that provides an output quantity having a specified relation to the input quantity

[SOURCE: OIML V 2-200:2012, 3.7 ^[2] ]

3.1.7

performance test

test to verify whether the load cell under test is capable of performing its intended functions

3.1.8

rated operating condition

operating condition that must be fulfilled during measurement in order that a measuring instrument or measuring system perform as designed

(For notes, refer to the OIML V 2-200:2012).

3.1.9

sealing

means intended to protect the measuring instrument against any unauthorised modification, readjustment, removal of parts, software, etc.

(For notes, refer to the OIML V 1:2013).

3.1.10

type (pattern) evaluation

conformity assessment procedure on one or more specimens of an identified type (pattern) of measuring instruments which results in an evaluation report and / or an evaluation certificate

(For notes, refer to the OIML V 1:2013).

3.1.11

type approval

decision of legal relevance, based on the review of the type evaluation report, that the type of a measuring instrument complies with the relevant statutory requirements and results in the issuance of the type approval certificate
