Description by Little App Company (from Google Play)

UP/1B Calculator is a step-by-step guide and calculation tool for Gas Safe registered engineers carrying out installation pipework tightness testing to IGEM/UP/1B Edition 4.
The app guides you through every stage of the tightness test procedure:
• Initial Volume Test (IVt) — calculates the correct test pressure and acceptable pressure drop for the installation size
• Let-By Test — checks for meter regulator let-by
• Tightness Test — records pressure readings and determines pass or fail
• LDF Check — guides leak detection fluid testing of all disturbed joints
• Purge — calculates purge volume and checks for safe gas release
• PDF Record — generates a professional gas tightness test record ready to save or share
Designed specifically for natural gas installations at low pressure (nominal operating pressure ≤ 21 mbar) in accordance with IGEM/UP/1B Edition 4.
All test records are saved to your account and sync across devices — ideal for engineers working across multiple sites.
For use by Gas Safe registered engineers only.
