What this means
- The maker's rating, not our measurement. The highest cabin temperature or the lowest water temperature each maker rates its product to.
- Where its pages disagree, the less favourable figure counts. A maker that prints two figures is counted at the one it can stand behind.
- Room and weather change it. A cold garage or a hot day moves what a unit reaches; few makers say at what room temperature they rated it.
