Specificity is the ability to assess unequivocally the analyte in the presence of components which may be expected to be present. Typically these might include impurities, degradants, matrix, etc. Lack of specificity of an individual analytical procedure may be compensated by other supporting analytical procedure(s). This definition has the following implications:

Identification:
To ensure the identity of an analyte.

To ensure that all the analytical procedures performed allow an accurate statement of the content of impurities of an analyte, i.e., related substances test, heavy metals, residual solvents content, etc.

Assay (content or potency):
To provide an exact result which allows an accurate statement on the content or potency of the analyte in a sample.

Software Qualification:

(Software) Validation:
Confirmation by examination and provision of objective evidence that (software) specifications conform to user needs and intended uses, and that the particular requirements implemented (through software) can be consistently fulfilled.

(Software) Verification:
Verification provides objective evidence that design outputs of design development meet all specified requirements. (Software) verification looks for consistency, completeness (of software) and its supporting documentation.

Sterility assurance level (SAL):
The SAL of a sterilising process is the degree of assurance with which the process in question renders a population of items sterile. The SAL for a given process is expressed as the probability of a non-sterile item in that population. An SAL of 10-6 for example, denotes a probability of not more than one viable micro-organism in 1 × 106 sterilised items of the final product. The SAL of a process for a given product is established by appropriate validation studies.

The effect of excursions due to equipment failure should be addressed and reported if judged to affect stability results. Excursions that exceed the defined tolerances for more than 24 hours should be described in the study report and their effect assessed.
