From my understanding Tolerable rate is the maximum deviation rate you would accept without changing your reliance on the control, the expected rate is the auditors best estimate. Usually you need to compare the upper deviation rate (actual sample deviation rate + allowance for sampling risk) to the tolerable rate to determine whether the

The hazard rate function , also known as the force of mortality or the failure rate, is defined as the ratio of the density function and the survival function.That is, , where is the survival model of a life or a system being studied. In this definition, is usually taken as a continuous random variable with nonnegative real values as support. In this post we attempt to define the hazard rate acceptability levels. An acceptable maximum rate of the considered hazard occurrence noted THR (Tolerable Hazard Rate) is determined by a number of events per hour [2]. In principle, the operator should specify the THR so that the system designer is able to determine whether their system design is capable of meeting the target. Still, some safety practitioners profess that only a risk-free environment is acceptable. These two examples illustrate that view: At a recent safety conference, a speaker reviewed the hazard analysis and risk assessment methods used in his company and said the outcome to be achieved through the use of those methods was acceptable risk. A definition of acceptable risk with examples. Acceptable risk is a risk exposure that is deemed acceptable to an individual, organization, community or nation. Acceptable risks are defined in terms of the probability and impact of a particular risk.They serve to set practical targets for risk management and are often more helpful than the ideal that no risk is acceptable.
