What must be done to determine if the protective cap on a cylinder is compliant?

To determine if the protective cap on a cylinder is compliant, impact testing according to standards is essential. This testing evaluates how well the cap can withstand impact, ensuring that it meets safety regulations and can protect the cylinder from damage during transportation and handling. A compliant cap should remain intact and functional even in the event of a drop or collision, which is critical for safety.

Visual inspection for color may not provide sufficient information about the cap's structural integrity. Similarly, consulting outdated resources could lead to relying on information that no longer reflects current safety standards, which can compromise safety. Lastly, performing a weight check does not assess the compliance or functionality of the protective cap since weight alone does not indicate whether the cap meets the necessary safety criteria.
