# IST Report

As soon as you submit, the app produces a lab-style PDF certificate for the job. It sets out the result of each test, an overall pass of fail, and recommendations on how to treat the system if anything needs attention.

### Example Instant System Test Report

This anonymised report comes from a heat pump system over 10 years old, protected with Fernox HP-5 and tested during a routine service. It passed every test:

![Fernox Instant System Test Results report showing sample and property details, an address map, four test results, conclusion, and recommendation. Visible: Instant System Test Results, Sample Details, Address, Property Details, Results, Turbidity Sample.](https://staticfiles.gleap.io/ghelparticle/2XHUeDkjhDx8LmdlWnW3Bg4fxFmGnwtJfthjZXo9WjiN65FMfpe3raJdHngv9xYFtrE0QwJVsjv.png)

The report concluded that the system complies with BS 7593:2019 and should be re-sampled in one year. Because it passed, no corrective action was recommended.

The report is emailed to you, and you can choose to send it to your customer and other contacts too. Every report is also stored in your account, so you can find it later in the app or the Fernox web portal.

Linked managers can also choose to receive reports submitted by the engineer.

That makes the report useful well beyond the day of the visit:

-   **For the customer:** clear evidence that their system was tested and is protected.
    
-   **For warranty claims:** a dated record of water quality to show the boiler manufacturer.
    
-   **For your business:** a searchable history of every system you've tested, ready for any future call-out.
