LTPD is the same as RQL, the rejectable quality level. It is the quality level at the consumer's point of the oc curve. The consumer's risk is the risk that a sampling plan will accept a lot, if the true lot quality is RQL. Both points -the consumer's and the producer's - should be specified. There is a lot more information about this starting at:
