A more recent UK standard often replacing or supplementing BR 3021 for specific vessel classes.
BR 3021 categorizes equipment based on its location within the vessel, as different areas experience varying shock intensities: Shock Grade Application Area Vertical Severity Lateral Severity Below the waterline (Hull-mounted) 120g, 8 ms NSS Grade II Above the waterline (Deck/Bulkhead) 50g, 11 ms 22g, 11 ms br 3021 standard pdf
Standardizing the methods used to simulate shock loading on heavy-duty or lightweight horizontal shock machines. Key Technical Classifications: NSS Grades A more recent UK standard often replacing or
The primary objective of BR 3021 is to define the mechanical shock severities that onboard equipment must withstand. It provides a framework for: It provides a framework for: The modern Maritime
The modern Maritime Acquisition Publication that provides updated guidance on naval shock requirements.
The (often referenced as Book of Reference 3021 ) is a critical naval engineering specification focused on the shock requirements and testing for equipment and systems installed on combatant ships . Primarily utilized by the UK Ministry of Defence (MoD) and international partners like the Indian Navy, it ensures that vital shipboard components—from electronic displays to heavy propulsion units—can survive and remain operational following underwater explosions (UNDEX).
