The reporting process

A record you can use.

Testing is carried out in accordance with I.S. EN ISO 9972:2015. The report records the test conditions and measured air permeability so performance can be assessed against the project target.

Agree the required report format, recipients and issue date before booking. Any diagnostic investigations or subsequent retests are scoped separately.

  • Building and test identification
  • Test method and preparation conditions
  • Measured results and the agreed project target

After the test

Plan the next step.

If the building does not achieve the agreed target, the result is recorded and further investigation can be discussed. Your project team can then plan remedial improvements and a retest.

Reporting times are agreed in your quotation. Tell us about any certification or handover deadline at the start.
