In short
Easy is a skill. Most of your erg week should be easy enough to talk in full sentences.
The check: say a full sentence out loud.
A few words at a time means you've left easy.
Heart-rate zones differ from person to person, so a chart off the internet may not fit you.
How to run and pace each test, and how to read the result.

Paper
Stöggl T, Sperlich B (2014) Front Physiol 5:33, doi 10.3389/fphys.2014.00033, PMID 24550842 (9 weeks, 48 well-trained endurance athletes: the polarised group trained 68% of the time at low intensity, 6% at threshold, 26% high, and improved most; the intro cites elite athletes doing ~75% of training below the lactate threshold. Polarised: keep easy easy, hard hard; slides 1, 2, 5: most of the week easy, the grey middle)
Nothing here is medical advice. The tests are maximal efforts: if you have a health condition or any doubt about training this hard, check with a doctor first, and stop if you feel unwell.
