In cross-over designs, sequences of treatments are applied to the units, spread over a specified period of time. The model for the estimation of such designs includes a carryover term, which makes them competent for use in consumer research trials. Construction of useful cross-over designs in the context of consumer research trials forms the body of this work and some new classes of partially balanced cross-over designs with two associate classes [PBCOD(2)] are obtained, along with their efficiencies. Designs constructed are uniform over periods for a large number of units and they estimate treatment contrasts with two sets of precision.
