EN 1300 – High Security Locks

European standard for high-security locks intended for safes, vaults, ATM systems, and secure storage applications (edition commonly referenced on certificates, e.g. EN 1300:2018 — confirm on your test report).

EN 1300 specifies requirements and test methods for high-security locks and related components (lock cases, cylinders, etc.) used where resistance to attack and manipulation must be high. It is complementary to, but different from, EN 12209, which covers mechanically operated locks and locking plates for general doors, windows, and shutters.

Classification (overview)

EN 1300 uses lettered security classes (e.g. A, B, C …) for different lock types and attack resistance. The exact class label on your project must match the certificate for the lock model fitted. A typical bank-grade specification may call for a high class (e.g. Class A) for an auxiliary or high-security lock used together with a multipoint lock on a secure-storage doorset.

Relationship to secure-storage doors (EN 1143-1)

EN 1143-1 classifies the complete secure storage unit or doorset for burglary resistance. Locks certified to EN 1300 are often specified as part of that assembly so that locking hardware matches the threat model (drilling, punching, manipulation). Always specify locks that appear on the same certification / technical file as the doorset where a combined rating is required.

Relationship to EN 12209 multipoint locks

A doorset may combine a multipoint lock meeting EN 12209 (including security grade requirements) with an additional EN 1300 high-security lock. Our bank-designated door product page lists main multipoint lock to EN 12209 and additional lock to EN 1300 as typical of this class of specification.
