This specification is applicable to the calibration of ventilator testers.
Current Category: CN-JJF - National Metrology Technical Specifications JJF
This specification is applicable to the calibration of ventilator testers.
This standard applies to the calibration of anesthesia machines with ventilation functions, but not to the calibration of non-ventilated pain relief equipment.
This specification applies to the calibration of phantoms used in detachable medical magnetic resonance imaging (MRI) systems for the detection of imaging performance parameters such as spatial resolution and density resolution, but it does not apply to MRI phantoms with other special functions.
This specification applies to the calibration and in-use inspection of instruments used to measure the linear expansion coefficient of solid materials (excluding film materials).
This specification applies to the calibration of the dynamic response (heat response time) of contact temperature sensors with a time constant of not less than 1 ms at room temperature to 1,700 °C, with an airflow Mach number of less than 0.95, or a liquid flow rate of less than 1 m/s. Temperature sensors mainly include thermocouples and resistance temperature sensors.
This standard applies to the calibration of automatic blood dialysis devices.
This standard does not apply to the calibration of peritoneal dialysis devices, blood perfusion devices, blood replacement devices, plasma adsorption devices, or continuous blood purification devices.
This standard applies to the calibration of industrial robots with three or more motion axes, which can be reprogrammed and controlled automatically.
This specification is applicable to the testing of pressure gauge calibrators.
This standard applies to the testing of self-contained open-circuit compressed air breathing apparatus (hereinafter referred to as air breathing apparatus), and its scope of application includes positive pressure air breathing apparatus, fire and emergency air breathing apparatus, and industrial air breathing apparatus.
This standard applies to the calibration of parameters related to the pacing function in external pacemakers, but it does not apply to the calibration of implantable pacemakers, inductive pacemakers, pacing electrodes, or other devices used for ECG simulation.
This standard applies to the calibration of superconducting and permanent magnet medical magnetic resonance imaging (MRI) systems with a field strength of 3.0 Tesla or lower.
This standard specifies the evaluation method for the interchangeability of standard substances in laboratory medicine, and is applicable to standard substances, quality control products, calibration products, and samples for interlaboratory quality assessment (EQA) and proficiency testing (PT) that require interchangeability evaluation. The uniformity and stability of samples are not within the scope of this standard. The content described in this standard assumes that the samples to be evaluated already meet the requirements for uniformity and stability. Note: This standard can also provide a reference basis for management departments, accreditation bodies, and other institutions to confirm or identify the capabilities of standard substance research and production institutions.
