IEC 60335-2-84 Toilet Seat Cover Mechanical Strength & Durability Test Machine 3 Test Stations

The Toilet Seat Cover Mechanical Strength & Durability Test Machine is a multi-function laboratory testing system developed for evaluating the mechanical strength, durability and operating performance of toilet seats and toilet seat covers.

Designed with reference to IEC 60335-2-84, Clauses 21.103.1 and 21.103.2, the system reproduces repeated opening, closing, loading, impact and side-force conditions that may occur during normal use.

Unlike a single-purpose toilet seat tester, the SN1901 combines multiple mechanical endurance tests into one integrated platform. Its servo motor-driven mechanism, pneumatic loading system, adjustable force angle and programmable test cycles allow laboratories and manufacturers to perform repeatable and controlled testing.

The equipment is suitable for toilet seat manufacturers, sanitary ware manufacturers, electrical appliance laboratories, quality inspection laboratories, certification organizations and third-party testing facilities requiring IEC-compliant mechanical durability testing.

The toilet seat ring and cover are repeatedly opened to the specified angle and allowed to return under controlled conditions.

This test helps evaluate:

• Seat and cover hinge durability
• Repeated opening and closing performance
• Structural integrity
• Cushion and hinge condition
• Long-term mechanical reliability

The opening angle is adjustable to 70° or more, while the operating time can be programmed according to the test requirement.

For toilet seats equipped with a damping or slow-closing mechanism, the tester measures the closing time during repeated operation.

The system can monitor whether the closing performance remains within the specified range after repeated cycles, making it useful for evaluating soft-close toilet seat durability and damping mechanism performance.

The tester applies controlled mechanical force during opening and closing operations to simulate demanding operating conditions.

The test can be used to evaluate:

• Slow-drop mechanism reliability
• Hinge strength
• Structural stability
• Mechanical endurance under increased loading

The opening/closing time and test cycles can be preset through the control system.

A controlled vertical load is applied to the toilet seat through a dedicated rubber and steel loading assembly.

The system supports loading up to 1250 N, allowing the test sample to be subjected to repeated static mechanical stress.

This test is intended to assess the seat's ability to withstand concentrated or distributed user loading without unacceptable deformation or damage.

The equipment applies repeated vertical loading to the toilet seat using a steel and rubber loading assembly.

The test force can reach 1250 N, with an operating frequency of 10-20 cycles/minute.

This provides a repeatable method for evaluating:

• Impact resistance
• Structural durability
• Seat deformation
• Mechanical fatigue
• Repeated load resistance

The tester applies alternating mechanical force to both sides of the toilet seat.

A maximum test force of 890 N can be applied to simulate uneven or lateral loading conditions that may occur during actual use.

The alternating left/right loading cycle provides an effective method for assessing toilet seat lateral strength and mechanical durability.

The SN1901 adopts a three-station laboratory test platform, allowing different test functions to be performed independently.

The combination of pneumatic and servo-driven mechanisms provides flexibility for different mechanical testing procedures.

Different fixtures can be installed according to the selected test method.

The opening and closing mechanism uses a 400 W servo motor, providing controlled and repeatable movement.

For swing and impact loading, pneumatic cylinders are used together with pressure sensing and regulation to provide stable mechanical force.

This hybrid drive architecture enables the machine to handle both dynamic movement testing and controlled force loading within one test platform.

The machine integrates a 7-inch touch-screen interface with PLC control, allowing operators to set and monitor key test parameters.

The programmable system can control parameters such as:

• Test cycles
• Opening/closing angle
• Operating time
• Force application time
• Test frequency
• Left/right force sequence
• Test duration

With a programmable range of up to 999,999 cycles, the tester is suitable for extended mechanical endurance testing in professional laboratories.
