Section 1212.14 - Qualification testing(a)Testing. Before any manufacturer or importer of multi-purpose lighters distributes multi-purpose lighters in commerce in the United States, surrogate multi-purpose lighters of each model shall be tested in accordance with § 1212.4 to ensure that all such multi-purpose lighters comply with the standard. However, if a manufacturer has tested one model of multi-purpose lighter, and then wishes to distribute another model of multi-purpose lighter that differs from the first model only by differences that would not have an adverse effect on child resistance, the second model need not be tested in accordance with § 1212.4 .(b)Product modifications. If any changes are made to a product after initial qualification testing that could adversely affect the ability of the product to meet the requirements of the standard, additional qualification tests must be made on surrogates for the changed product before the changed multi-purpose lighters are distributed in commerce.(c)Requalification. If a manufacturer or importer chooses to requalify a multi-purpose lighter design after it has been in production, this may be done by following the testing procedures at § 1212.4 .
