- Incubation period 3-70 days, most often 21 days
- test doses used, duration of exposure and post treatment incubation period,
- Epidemiological link, during the incubation period, is defined as one of the six following:
- The incubation period is normally one to three weeks, but may be as long as three months.
- The standard samples must be taken from each production unit from poultry already hatched from eggs collected during the incubation period.
- Depending on the reconstructed human epidermis model used, the exposure period may vary between 15 to 60 minutes, and the incubation temperature between 20 and 37 °C.
- Certain products derived from poultry slaughtered before 1 February 2006 should continue to be authorised, taking into account the incubation period of the disease.
- Certain products derived from poultry slaughtered before 1 September 2005 should also continue to be authorised, taking into account the incubation period of the disease.
- Certain products derived from poultry slaughtered before 15 February 2006 should also continue to be authorised, taking into account the incubation period of the disease.
- Certain products derived from poultry slaughtered before 1 August 2005 should also continue to be authorised, taking into account the incubation period of the disease.

- Certain products derived from poultry, ratites and farmed and wild feathered game slaughtered or hunted before 15 February 2006 should continue to be authorised, taking into account the incubation period of the disease.
- During the test optimisation phase (9, 10, 11, 12, 13), a 42 hours post-treatment incubation period proved to be optimal and was therefore used in the validation of the reference test methods.
- The initial biomass in the test cultures must be the same in all test cultures and sufficiently low to allow exponential growth throughout the incubation period without risk of nutrient depletion.
- The incubation period is difficult to estimate and probably varies with the strain of virus and host, usually five to six days is quoted, but the range for individual birds is probably from a few hours to about seven days.
