Any PDF of the EJMA standards found online is guaranteed to be an outdated edition (such as the 9th or 10th Edition) and may be of questionable quality or accuracy. Using a superseded or incomplete version for a critical design project could lead to safety risks, regulatory non-compliance, and costly failures. As a sign of the times, EJMA has even introduced a system of digital subscriber badges that companies can display on their websites. These badges contain a link that allows anyone to verify that the company is a current, active subscriber to the latest standards, making it easy to distinguish legitimate users from those relying on outdated information.
