Australian Pressure Laboratory (APL) has held NATA accreditation to ISO17025 continuously since 1994.  Our accreditation in pressure is among the broadest with lowest uncertainties of all commercial laboratories in Australia. 

Highlights include:

  • Uncertainties as low as 0.003% (30 ppm) from vacuum to 2500 kPa and 0.005% (50 ppm) up to 80,000 kPa
  • Very low draft pressures, as required for clean room and HVAC applications, with least uncertainty of 0.3 Pa
  • Very high hydraulic pressures up to 275 MPa, as required for oil/gas exploration industries
  • Pneumatic testing up to 12,000 kPa allowing calibration of high pressure pneumatic pressure controllers
  • Absolute pressure with uncertainties down to 5 Pa enabling calibration of precision barometers and Air Data Test Sets
  • Dead Weight Tester calibration from vacuum to 275 MPa

Key to our capability is the use of Dead Weight Testers throughout our laboratory which are the most stable and reliable references for calibration of high accuracy pressure instruments. This enables us to determine the performance of your instruments with the lowest uncertainties.

Our current scope of accreditation can be found on the NATA website here: http://www.nata.com.au/nata/component/jumi/scopeinfo?key=9720

Through the ILAC Mutual Recognition Agreement (MRA), APL certificates are also recognised internationally and our certificates include the ILAC combined mark.  More information on ILAC and the MRA can be found here: http://ilac.org/ilac-mra-and-signatories/
