IN LAB AERONAUTICS

Accredited calibration laboratory — ISO/IEC 17025

IN LAB AERONAUTICS is an accredited calibration laboratory, according to the requirements of EN ISO/IEC 17025. Our laboratory is fully capable of calibrating:

01 РПК-7.2.1-04: 2023

Pressure

Calibration of pressure gauges — electromechanical and mechanical

The laboratory calibrates electromechanical and mechanical pressure gauges (water, oil, air). Calibration is performed with a precision pressure calibrator Fluke 717-10000G. The laboratory also has Air Data Test Set equipment.

Equipment used
Fluke 717-10000G Air Data Test Set
01 · Pressure Pressure gauge calibration
02 РПК-7.2.1-02: 2023

Torque

Calibration of torque tools — wrenches and screwdrivers

The calibration is performed with a dedicated stand and two Stahlwille force sensors.

Equipment used
Stahlwille stand 2× force sensors
02 · Torque Torque calibration Stahlwille force sensor Stahlwille
03 РПК-7.2.1-05: 2023

Mass

Calibration of scales with non-automatic action — on site at the customer

Calibration of scales with non-automatic action is carried out on site at the customer. The laboratory has a set of reference weights, class M1 (from 1 mg to 2 kg), weights of 5 kg and 10 kg.

Equipment used
M1 weights (1 mg – 2 kg) 5 kg weights 10 kg weights On-site service
03 · Mass Mass / scales calibration
04 РПК-7.2.1-01: 2023 and РПК-7.2.1-06: 2023

Length

Calibration of calipers and cylindrical length measures

Calibration of calipers is carried out with standard parallel end measures, class 1. Calibration of cylindrical length measures is carried out with a micrometer — guaranteed accuracy for class-1 metrology standards.

Equipment used
Class 1 parallel end measures Micrometer
04 · Length Length calibration Class 1 end measures Class 1 standards
05 РПК-7.2.1-03: 2023

AC/DC Voltage & Current

Constant and alternating voltage and current — combined or separately

Calibration is performed with a multi-function constant and alternating voltage and current generator 5100B. Voltage and current can be combined into a single measurement or calibrated independently.

Equipment used
5100B generator AC + DC voltage AC + DC current
05 · Electrical AC/DC voltage and current calibration
06 РПК-7.2.1-07: 2023

Resistance

Calibration of instruments for measuring electrical resistance

The calibration is performed with three multi-valued resistance measurements, ensuring precision across a wide range of values.

Equipment used
3× multi-valued standards
06 · Resistance Resistance calibration
07 РПК-7.2.1-08: 2023

Capacitance

Calibration of instruments for measuring electrical capacitance

The calibration is carried out with a multi-valued capacitance measure P5025 — a reference standard ensuring repeatability and traceability.

Equipment used
P5025 capacitance standard
07 · Capacitance Capacitance calibration
08 РПК-7.2.1-09: 2023

Frequency

Calibration of instruments for measuring frequency

The calibration is performed with a functional waveform generator Agilent 33120A — a professional standard for frequency measurements in aviation electronics.

Equipment used
Agilent 33120A Functional waveform generator
08 · Frequency Frequency calibration Agilent 33120A waveform generator Agilent 33120A
Lab Conditions

Laboratory Conditions

All methods are worked precisely and according to the rules described in them. After each calibration, a certificate is issued, which is checked by the head or deputy head of the laboratory.

Calibration is carried out under ambient conditions in the temperature range (20 ± 4) °C and relative humidity from 15 % rh to 70 % rh. The laboratory has qualified, trained and experienced staff.

In the near future we plan to expand the scope of the laboratory.
