Patent ID: 7076387

Claim:
A method for testing a first product based on an equivalency index associated with a parameter of the product, comprising: a. identifying at least one measurable parameter of the first product; b. measuring the parameter on a group of the first product; c. measuring the parameter on a group of second products possessive of known desirable quality; d. arranging data of steps b and c in an array having a total number of array elements; e. providing a numeric upper limit and a numeric lower limit relating to the array, the upper limit being greater in magnitude than the lower limit, at least one array element having a magnitude between the upper limit and the lower limit; f. calculating an equivalency index relating to the quotient of dividing the number of array elements greater in magnitude than the lower limit and smaller in magnitude than the upper limit by the total array elements; and g. providing a criterion and comparing the equivalency index to the criterion to determine whether the first product and the second product are equivalent.
