Referring to their object-protecting characteristics penetration-resistive sandwich elements are to be classified in a higher level than glazing with resistance to thrown objects (manual attack). DIN EN 356 specifies the requirements and test methods for penetration-resistive glazing, which is intended to retard external forceful impacts on objects and/or persons within a protected area during a short period of time.
If applied, penetration-resistive sandwich elements should be integrated in frames or structures that themselves provide a reasonable resistance to attacks. Generally, they are divided in classes P6B, P7B and P8B. There are test certificates available issued by ift (Institut für Fenstertechnik) for all three classifications.
