3.9
manufacturer
natural or legal person who manufactures a medical device for intended use on his behalf with responsibility for the design and/or manufacture of the medical device, regardless of whether these operations are carried out by that person himself or on his behalf by another natural or legal person(s)
Note 1: The “natural or legal person” has ultimate legal responsibility for ensuring compliance with all applicable regulatory requirements for the medical device in the countries or jurisdictions where it is intended to be made available or sold, unless such responsibility is specifically imposed on another natural or legal person by the Regulatory Authority (RA) within that jurisdiction.

3.10
precision of measurement
closeness of agreement between the measurement indications and the measurements obtained from repeated measurements for the same or similar measured objects under the specified conditions
Note 1: The degree of precision is expressed numerically by the statistical measures of imprecision of measurements, such as standard deviation and coefficient of variation, that are inversely related to precision. Quantitative measures of precision depend on the stipulated conditions
Note 2: Precision of a given measurement procedure is subdivided according to the specified precision conditions. Particular sets of extreme conditions are termed repeatability and reproducibility.

3.14
measurement trueness
trueness
closeness of agreement between the average value obtained from infinite series of repeated measurements and a reference value

confirmation that the specified requirements meet the intended use
Example: The procedure for measuring creatinine concentration in human serum can also be confirmed for the determination of creatinine in human urine.
Note: Validation in GB/T 19000-2016 3.8.13 is defined as: confirmation, through provision of objective evidence, that the requirements for a specific intended use or application have been fulfilled.
[Source: GB/T 29791.1-2013, 3.72]
3.16
verification
provision of objective evidence for a given item to confirm that specified requirements have been fulfilled
Example 1: Confirmation of the uniformity claimed for a given reference material in terms of its measurement value, and related measurement procedure and measured part, up to a mass of 10mg.
Example 2: Confirmation that the measuring system meets the performance characteristics or statutory requirements.
Example 3: Confirmation that the target measurement uncertainty can be fulfilled.
Note 1: A given item can be, for example, a process, measurement procedure, material, compound or measuring system.
