Which is NOT a characteristic of an Independent Laboratory?

An independent laboratory is defined by its objectivity and impartiality in testing and evaluation. The characteristic of being owned by the equipment manufacturer directly undermines its independence. If a laboratory is owned by the manufacturer, there may be conflicts of interest that could compromise the integrity of its testing processes and results.

In contrast, laboratories that are truly independent operate without influence from manufacturers, enabling them to provide unbiased evaluations. Engaging in testing and evaluation is fundamentally a role of independent laboratories, as it is their primary function. Additionally, utilizing calibrated testing instruments is a standard practice essential to ensure accurate and reliable results, reinforcing the credibility of their evaluations. Therefore, the correct understanding of an independent laboratory highlights that any ownership by the manufacturer contradicts its foundational principles of independence and impartiality.
