Which of the following is NOT typically included in hard hat markings?

Hard hats are essential for safety in construction and other similar environments, offering protection against head injuries. The markings found on hard hats serve specific purposes related to safety standards and identifying the helmet's specifications.

The manufacturer's name is included to indicate who produced the hard hat, which is important for recalls or quality assurance. The date of manufacture is marked to inform users of the age of the helmet, which is crucial since hard hats have a limited lifespan and can degrade over time. The size is necessary for ensuring a proper fit, enabling the hard hat to offer optimal protection.

Test results, however, are not part of the standard marking on hard hats. While hard hats undergo testing to meet safety standards, the specific test results are not included as part of the helmet’s markings. This distinction emphasizes that the essential information needed for the hard hat's functionality and regulatory compliance is prioritized over individual testing outcomes.
