Proficiency Testing Australia
Print |

Designed to meet the needs of industry and research laboratories, this program follows the success of our Digital Multimeter and Temperature Measurement programs.

The program was developed following suggestions from industry and our goal is to offer a valuable and customer focused proficiency testing service. One Instromet rotary gas flow meter was provided. The tests included flow rate, absolute pressure, temperature, relative humidity, pressure loss across inlet/outlet of meter and % Error.

Four laboratories from Australia and one laboratory from New Zealand participated in the program, with all laboratories submitting results.

The overall performance by the participating laboratories is acceptable and within expectations. Measurement uncertainties stated by all laboratories are within acceptable range.

PTA programs have been used by laboratories to satisfy accreditation requirements, educate staff, verify methods and procedures, enhance accuracy, demonstrate competence, assess performance, compare with peers, monitor analysis, identify problems and improve testing

The Final Report is issued on the PTA website: The report will be accessed by selecting Programs, then selecting Reports 2018. The report number is 1071

The second round is scheduled for late 2018.
