Door and window product testing
The core of door and window product testing focuses on four dimensions: safety performance, functional use, durability, and energy efficiency. It covers various types of doors, windows, and supporting components, and specifies testing requirements based on standards to ensure that the product is suitable for building use scenarios.
Testing Scope
By product type: plastic doors and windows, aluminum alloy doors and windows, steel doors and windows, wooden doors and windows, aluminum wood composite doors and windows, broken bridge aluminum doors and windows, system doors and windows, fireproof doors and windows, explosion-proof doors and windows, insulated doors and windows, etc;
By application scenario: exterior doors and windows of buildings (residential, office buildings, shopping malls, etc.), interior doors and windows of buildings, curtain wall opening fans;
Supporting components: door and window frames, sashes, glass (insulated glass, tempered glass, laminated glass), sealing strips, hardware (hinges, handles, locks, sliding supports), sealant, drainage system, screen windows, etc.
Testing Content
(1) Security performance testing
Wind resistance performance: Test the deformation and damage of doors and windows under specified wind pressure;
Waterproof performance: Simulate rainfall environment and detect leakage in door and window gaps;
Air tightness performance: Check the air tightness of doors and windows, and classify them according to the penetration rate (levels 1-8);
Glass safety performance: glass fragment state, bonding strength of laminated glass, impact resistance of explosion-proof glass;
Fire resistance performance: fire integrity, thermal insulation, graded according to GB/T 7633.
(2) Use function detection
Opening and closing performance: opening and closing force, repeated opening and closing life, opening and closing flexibility;
Locking performance: lock interlock rate, multi-point lock synchronization locking effectiveness, anti-theft performance (;);
Drainage performance: Simulate rainfall to test the effectiveness of the drainage system, without water accumulation or leakage;
Sealing performance: The adhesion between the sealing strip and the frame fan, the sealing reliability between the glass and the profile, and the long-term use without aging or detachment.
(3) Durability testing
Corrosion performance: Salt spray test for door and window profiles, hardware components (;
Aging performance: high and low temperature cycling test, ultraviolet aging test for plastic doors and windows;
Durability of hardware components: closing speed of door closers, accuracy of ground spring return, and lifespan of repeated actions;
Aging of sealing strip: After thermal aging and ozone aging, there is no cracking or shrinkage, and the elasticity retention rate is ≥ 80%.
(4) Energy saving performance testing
Thermal insulation performance: Check the heat transfer coefficient K value, and the K value of insulated doors and windows should be ≤ 2.8W/(㎡· K);
Sound insulation performance: air sound insulation capacity;
Sunshade performance: Sunshade coefficient SC;
Hollow glass performance: dew point, sealing life.
(5) Material and structural testing
Profile performance: material grade verification, wall thickness dimension deviation, tensile strength, bending strength;
Glass performance: visible light transmittance, shading coefficient, heat transfer coefficient, and impact resistance of tempered glass;
Connection strength: splicing strength of profiles, bonding strength between glass and profiles, and firmness of hardware installation;
Harmful substances: formaldehyde emissions from plastic doors and windows, heavy metal precipitation from profiles.
