The Instrument Bench — reference
Tables, formulas, and the code map.
The reference bench a working engineer keeps within reach — searchable, exam-honest, and free to use. On exam day you'll use the real code books; here you build the lookup-and-apply skill.

Drawer 01
Property tables
Original tables from the public-domain IAPWS-IF97 standard — practise the lookup-and-interpolate skill you will use on exam day.
Drawer 02
Formula reference
Every formula with its variables, units, and the exam trap to watch for.
Drawer 03
Where to find it in the codes
Original navigational maps of the CSA/ASME landscape — which code, which section, and how to use it. We never reproduce the code text itself.
Working calculators
Each calculator shows its work step by step — the worked-example walkthrough, not just an answer — and hands you straight into a drill on the same concept. The first is live now; the rest are in the forge.
Live calculator
Steam-table interpolator
Read a property between two printed rows — the exact skill you use on exam day. It shows every step of the arithmetic, then hands you into a drill.

In the forge — soonBoiler efficiency
Output over input, with the show-the-work walkthrough
Combustion & excess air
Air-fuel ratios and stack-loss checks
PRV capacity
Relief sizing against Napier's rule

Jurisdiction & certification navigator
Pick your province — ABSA, TSSA, Technical Safety BC, TSASK, or Manitoba — and get the booking process, certificate ladder, and reference-code editions for your exact regulator. In the forge now; until it lands, your provincial regulator’s official site is the authoritative source for fees and sitting dates.
Questions about your jurisdiction? Ask usOur own original tables, formulas, and code maps. Physical constants are public-domain thermodynamic facts (IAPWS-IF97); we never reproduce CSA/ASME text. On exam day you’ll use the actual code books — this bench trains the skill of finding and applying what they contain.
