Product Overview
The IEC 60335-1 Appliance Internal Wire Flexing Test Machine (Model: ZLT-WM1A) is a professional testing instrument designed to evaluate the durability of internal wires in electric appliances. It performs continuous bending tests via swivelling movements, focusing on internal wires that connect movable instrument parts (e.g., a blender’s rotating base or a vacuum cleaner’s extension wand) during normal use or maintenance.
The machine strictly complies with IEC60335-1 clause 23.3, IEC60065, and IEC60950—key international standards for appliance safety—ensuring that manufacturers can verify whether internal wires withstand repeated bending without breaking (which could cause short circuits, electric shocks, or fire hazards). Its robust design, precise control systems, and wide compatibility make it a critical tool for quality control in appliance production lines and third-party testing labs.

Product Features
Wide Flexing Angle for Realistic Simulation
With a flexing angle greater than 130°, the machine accurately simulates the bending stress that internal wires experience in movable appliance parts (e.g., a vacuum cleaner’s hose joint or a mixer’s tilting head). This angle exceeds the minimum requirements of IEC60335-1 clause 23.3, ensuring that tests reflect real-world use conditions.
Stable & Adjustable Flexing Speed
The machine operates at a consistent flexing speed of 30 times per minute, which can be adjusted (if needed) to match specific appliance use scenarios. Stable speed control prevents test variability—critical for comparing wire durability across different batches or models.
High Voltage & Power Capacity
With a maximum voltage output of 240V and power output of 3KW, the ZLT-WM1A can test internal wires used in both low-power (e.g., small blenders) and high-power (e.g., electric stoves, air conditioners) appliances. This wide range eliminates the need for multiple test machines, reducing equipment costs.
Multi-Standard Compatibility
The machine complies with three major IEC standards: IEC60335-1 clause 23.3 (household appliances), IEC60065 (audio/video equipment), and IEC60950 (information technology equipment). This versatility allows it to test internal wires for diverse product categories, from microwaves to laptops.
User-Friendly Operation
The machine features a simple control panel for setting flexing speed, test duration, and voltage/power levels. It also includes safety guards to prevent accidental contact with moving parts, ensuring operator safety during long test sessions.
Application
Internal Wire Testing for Movable Household Appliances
Small Appliances: Blenders (tilting heads), vacuum cleaners (extension wands), electric can openers (rotating blades), and irons (swivel cords).
Large Appliances: Washing machines (door hinges), ovens (pull-out racks), and refrigerators (drawer slides).
The machine tests whether internal wires in these movable parts withstand repeated bending without insulation damage or conductor breakage.
Quality Inspection for Appliance Maintenance
For repair and maintenance service providers, the ZLT-WM1A can test internal wires of used appliances (e.g., a worn vacuum cleaner’s wire connections) to determine if they need replacement, preventing post-repair safety hazards.
Compliance Testing for Electrical Connections
Certification Testing: Manufacturers use the machine to generate test data for CE, UL, or CB certifications, proving that internal wires meet IEC60335-1 and other standard requirements.
Pre-Production Testing: During product development, the machine helps identify weak wire designs (e.g., insufficient insulation) before mass production, reducing recall risks.
IT & Audio/Video Equipment Testing
IT Devices: Laptops (screen hinges), printers (paper trays), and desktop fans (rotating blades).
AV Equipment: Projectors (tilting lenses), speakers (adjustable stands), and televisions (swivel bases).
The machine’s compliance with IEC60950 and IEC60065 makes it suitable for testing internal wires in these devices.
FAQ
What is the flexing speed of the ZLT-WM1A machine?
The standard flexing speed is 30 times per minute, which can be adjusted to match specific appliance use conditions (e.g., faster speeds for high-use parts like vacuum cleaner wands).
What is the maximum voltage output supported by the machine?
The machine offers a maximum voltage output of 240V, which is sufficient to test internal wires used in most household, commercial, and IT appliances (including high-voltage devices like electric stoves).
Which IEC standards does the ZLT-WM1A comply with?
It complies with three key standards: IEC60335-1 clause 23.3 (household appliance internal wire testing), IEC60065 (audio/video equipment), and IEC60950 (information technology equipment).
What is the purpose of the internal wire flexing test?
The test evaluates whether internal wires in movable appliance parts can withstand repeated bending without insulation damage, conductor breakage, or short circuits. This prevents safety hazards like electric shocks or fires caused by faulty wires.
Can the machine test wires of all thicknesses?
The ZLT-WM1A is compatible with most common internal wire thicknesses used in appliances (from 0.5 mm² to 2.5 mm²). For extremely thick or thin wires, it is recommended to confirm compatibility with the manufacturer to ensure accurate test results.
