![]() ![]() The method according to claim 16, further comprising: producing a lot of the products taking a sample group of products from the lot determining the values of the variable under test for each product of the sample group comparing the values with a tolerance interval that is calculated using the tolerance band limit value and deciding whether to accept the lot or to reject the lot based on results of the comparison.Ģ4. ![]() The method according to claim 21, wherein the variable under test is a dial torque, a cap removal force, a cap placement force, or a breakage force.Ģ3. The method according to claim 16, wherein the products are medical devices or pharmaceutical products.Ģ2. The method according to claim 19, further comprising: testing whether the second location measure is smaller than the first location measure and if the second location measure is not smaller than the first location measure, increasing the chosen sample size and generating new samples that have an increased sample size and performing the obtaining step again, or if the second location measure is smaller than the first location measure, using the chosen sample size for defining a sampling plan or using the chosen sample size to calculate an improved value of the sample size for a sampling plan.Ģ1. The method according to claim 18, further comprising: calculating a first location measure for a first distribution that is represented by first sample tolerance band limit values which consider the risks of at least one producer and calculating a second location measure for a second distribution that is represented by second sample tolerance band limit values which consider the risks of the consumers.Ģ0. The method according to claim 16, wherein the at least one tolerance band limit value is a tolerance band limit value that considers risks of at least one producer of the products, or wherein the at least one tolerance band limit value is a tolerance band limit value that considers risks of the consumers of the products, or wherein the at least one tolerance band limit value comprises both of these tolerance band limit values.ġ9. The method according to claim 16, further comprising: testing whether a chosen sample size of the samples is great enough using the location measure of the tolerance band limit values, and if the chosen sample size is not great enough, increasing the chosen sample size and generating new samples that have an increased sample size and performing the obtaining step again, or if the chosen sample size is great enough, using the chosen sample size for defining a sampling plan or using the chosen sample size to calculate an improved value of the sample size for a sampling plan.ġ8. ![]() A method of determining at least one tolerance band limit value for a technical variable under test, the method comprising: obtaining the at least one tolerance band limit value from sample tolerance band limit values of different samples, wherein the samples comprise values of the technical variable under test of the associated sample, wherein obtaining the at least one tolerance band limit value comprises using a location measure of a distribution according to which the sample tolerance band limit values are distributed, wherein the technical variable under test is distributed according to an underlying extreme value distribution function, wherein each of the sample tolerance band limit values is calculable using a sample-specific conditional probability distribution function which is a function of sample values of the sample, and wherein the technical variable relates to a physical characteristic of a product that is producible in an industrial mass production process.ġ7. ![]()
