A certificate for security safes is not valid if :
- The safes are not anchored: safes that are carrying a grade for burglary protection and which weigh below 1000kg must be properly anchored to the floor or a wall, otherwise the classification is not valid as well as the label inside the safes.
- Unauthorised modifications are made to the safes. Changing the lock, adjusting the boltwork, replacing the seal or adding a deposit slot to burglary- or fire-resistant safes unvalidate the certification and the labels. Therefore, product checks, maintenance and customisation should be carried out by the original supplier or an accredited partner.
- The safes carry out unsufficient lock grade. If a safe is certified for burglary protection, then the lock used on the safe must also be certified as offering an equivalent degree of protection.
