Overview
ISO 15822:2007 - Test method of doorset opening performance in diagonal deformation (Seismic aspects) specifies a laboratory test method to evaluate whether a single-leaf doorset can be opened and unlocked after experiencing in-plane diagonal deformation representative of seismic action. The standard uses a static in-plane load to induce diagonal deformation and measures the forces and torques needed to unlock and open the door throughout a stepped deformation sequence.
Keywords: ISO 15822:2007, doorset opening performance, diagonal deformation, seismic aspects, in‑plane displacement, unlocking torque, opening force.
Key topics and requirements
- Scope: Applies to single-leaf doorsets; assesses opening function under in‑plane diagonal deformation by static load.
- Test principle: Gradually apply static force to produce diagonal deformation and measure the force/torque required to unlock and open the door.
- Test specimen: Installed in conditions equivalent to normal practical use; glazed areas use manufacturer’s specified glass or minimum specified thickness.
- Test apparatus:
- Rigid pin-joint test rig to secure the doorset,
- Device to apply static in‑plane force (upper or lower horizontal frame),
- Displacement measuring devices (horizontal and vertical) at defined exterior measuring points,
- Devices to measure opening force (pull/push at handle) and unlocking torque.
- Displacement steps: In‑plane displacement (R, in radians) is tested at eight standard steps: ±1/400, ±1/300, ±1/200, ±1/150, ±1/120, ±1/90, ±1/75 and ±1/60 (parties may agree alternative steps).
- Measurements and observations:
- Record unlocking torque (to 0.1 N·m) and opening force (to 10 N) at the first and third cycle of each step,
- Visually inspect and record deformation, damage, hardware abnormalities,
- Stop criteria: failure to operate or specified number of cycles completed.
- Results & reporting: Report in‑plane displacement, maximum unlocking torque, maximum opening force, deformation/damage locations and degree, test specimen identification, mounting method, test organisation and date.
Applications and who uses it
- Test laboratories: To perform standardized seismic performance tests on doorsets.
- Door and hardware manufacturers: To validate product design for seismic resilience and emergency egress performance.
- Specifiers and consultants: Architects, seismic and structural engineers use results to select compliant doors for buildings in seismic zones.
- Building code officials and safety assessors: Use test evidence when evaluating emergency egress and continuity of operation after earthquakes.
- Product certification bodies: Base conformity assessment and marking on standardized test data.
Keywords: doorset testing, seismic door performance, emergency egress, test rig, unlocking torque.
