The work begins with planning the quality assurance task in relation to the applicable standards, legislation and plant conditions. Measurement programmes are prepared to meet requirements in standards and legislation, and to enable practical work to be carried out efficiently.
Plan and perform AMS quality assurance to meet authority requirements and support correct tax-related measurements.
Industrial plants with automated measuring systems (AMS) are required to perform quality assurance within the timeframes set by the authorities. This is necessary to meet requirements from environmental and tax authorities and is relevant when AMS is used to measure NOx, SO₂ and CO₂.
QAL tasks and supplementary tests
Quality assurance of AMS helps ensure that the automated measuring systems are correctly adjusted and in compliance with applicable legislation and standards. The work is supported by a large stationary and mobile instrument fleet in the air laboratory, including equipment for specialised measurements, as well as air pollution specialists within air, odour and emissions, ensuring valid results and efficient execution without unnecessary additional work.

Challenges
When AMS quality assurance is missing, authority requirements and tax-related measurements become difficult to document.
Lack of quality assurance increases risk
Without documented AMS accuracy, emission reporting may fail to meet regulatory requirements, which can affect the plant’s operating permit and create a risk of restrictions or, in the worst case, shutdown.
Measurement errors affect financial outcomes
Inaccurate measurements of NOx, SO₂ and CO₂ can lead to incorrect tax calculations. This creates financial uncertainty and may result in overpayment, underpayment or disputes with authorities.
Inefficient execution increases costs
Lack of quality assurance can lead to repeated measurements, wasted resources and extended timelines, increasing costs and delaying regulatory processes.
Benefits
Get QAL2, AST, QAL3 and supplementary AMS documentation prepared for authority use.
Make informed decisions and ensure compliance
Accurate AMS measurements support emission reporting and handling of regulatory requirements. They provide a clear basis for audits and internal compliance processes.
Strengthen financial and operational control
Accurate measurements of NOx, SO₂ and CO₂ reduce the risk of incorrect tax payments. This supports financial clarity and stable plant operation.
Increase efficiency in compliance work
Avoid repeated measurements and unnecessary activities. This reduces time consumption, costs and administrative effort.
