Equivalent test method Clause Samples
The "Equivalent test method" clause defines the conditions under which alternative testing procedures may be used in place of those specifically referenced in a contract or technical specification. In practice, this clause allows a party to propose a different test method, provided it can be demonstrated that the alternative yields results comparable to the original method in terms of accuracy and reliability. This provision ensures flexibility in testing while maintaining quality standards, and it helps address situations where the specified test is unavailable, outdated, or impractical, thereby facilitating continued compliance and efficiency.
Equivalent test method. If a test method other than that given in paragraphs 2 or 3 of this annex is used, its equivalence must be demonstrated.
