How to use this worksheet

Use one row per sample and burn cycle. Give the sample a unique ID and link the appropriate test procedure and component documents.
Copy the exact wax, wick, vessel, fragrance, lot, process, and cure details. Use consistent units and name the basis of the fragrance percentage.
Write actual observation times and results. For measurements, include the instrument and location; attach photographs with the sample ID and time.
If a test stops early, record why. Start a separate series for a changed setup and list each changed component. A completed log does not determine whether a candle is safe to sell.

When to pause

Use an attended test area and the applicable procedure. Stop for abnormal flame, cracking, leakage, instability, unsafe heating, or other stated stopping conditions. This form supplies no universal test schedule or passing limit.

Completed example

This fictional sample was stopped after visible soot. Its dimensions, timing, and conditions illustrate record detail; they are not a recommended setup or test method.

Test series and cycle *	Wax and lot *	Wick *	Vessel measurements *	Fragrance and load *	Cure time *	Ambient conditions *	Burn cycle timing *	Flame behavior *	Melt pool *	Vessel temperature	Soot, mushrooming, and tunneling *	Decision and next controlled change *
C-17 / cycle 2	Coconut blend / W2606	W-3 / lot 22 / trimmed to documented baseline	V76 / 76 mm inside diameter / 92 mm high	Example fragrance / lot F2604 / masses and percentage basis in sample sheet	Poured July 1; tested July 12	23°C room; no draft; stable fire-safe surface	Lit 09:00; stopped 11:05 under procedure	Larger than established series baseline after 90 minutes	Measured and photographed at 60 and 120 minutes	Reading recorded at upper sidewall with instrument ID; no universal pass limit applied	Visible soot and wick mushrooming; no tunneling	Stopped under procedure; review component instructions before a separately identified comparison sample.
