No.
A safe with a burglary-resistant certification (for example EN 1143-1 or EN 14450) is not automatically fire-resistant. These standards only test burglary resistance, not fire protection.
A safe is only truly fire-resistant when it has been tested according to specific fire resistance standards, such as EN 1047-1, EN 15659, NT Fire 017 or UL 72.
Some safes combine both and therefore have a double certification for burglary and fire protection.
With us, these products are listed in the category fire safes, available from security level S2 up to class VI.

Also note that standards such as DIN 4102 relate to building materials and do not guarantee the protection of documents stored inside a safe.
