Last revised in 2018, BS 6262-4 states that installed safety glass should be marked as follows:

• Clearly and indelibly marked
• Name or trademark of manufacturer, merchant or installer
• Reference to product standard (e.g. BS EN 12150, BS EN 14449, etc.)
• Classification according to BS EN 12600

Only the first digit of the BS EN 12600 classification is necessary if the glass is intended for vertical glazing in critical locations.
