Ensuring electric blankets safe from electrical hazards requires extensive testing protocols that simulate both normal operations and potential failure modes. These tests protect consumers from the serious risks associated with electrical malfunctions.

Insulation Resistance Testing
Proper insulation prevents electrical current from traveling through unintended paths that could cause user shock or component damage. Testing laboratories measure insulation resistance between:
Live parts and accessible conductive surfaces
Input terminals and metal enclosures
Heating elements and external fabric layers
Control systems and grounding connections
Products must demonstrate insulation resistance exceeding minimum thresholds specified in applicable standards, typically requiring measurements above 1 megohm under normal conditions and at least 0.25 megohms after exposure to moisture.
Dielectric Strength Testing
Dielectric strength tests apply voltages significantly higher than normal operating levels to verify insulation can withstand electrical stress without breakdown.
Test voltages typically reach 1,000-2,000 volts AC applied for one minute, ensuring insulation integrity under worst-case scenarios. This testing identifies potential weak points in insulation systems before products reach consumers.


Leakage Current Measurement
Even properly insulated electric blankets allow minimal current flow through insulation and across surfaces. Testing protocols measure these leakage currents under both normal and single-fault conditions to ensure they remain within safe limits that pose no shock hazard to users.
Maximum permissible leakage currents typically range from 0.5 to 2.0 milliamperes depending on product classification and applicable standards.
Grounding Continuity Verification
For products incorporating grounding systems, testing verifies proper electrical continuity between grounding pins and accessible conductive parts. This ensures that in the event of insulation failure, fault currents flow safely to ground rather than through users.
Grounding resistance must remain below 0.1 ohms to provide effective protection.

Thermal Safety Testing: Preventing Overheating and Burns
Temperature-related hazards represent significant concerns for heated products. Comprehensive thermal testing ensures electric blankets safe from overheating scenarios that could cause user burns or fire.

Temperature Rise Testing
Products undergo extended operation at maximum settings while thermocouples monitor temperatures at critical locations including:

Testing continues until thermal equilibrium is reached, typically requiring several hours of continuous operation. Maximum temperature limits vary by location and standard requirements, but user-accessible surfaces must generally remain below 43°C (109°F) to prevent burn injuries during extended contact.

Abnormal Operation Testing
Safety standards require testing under fault conditions that could cause excessive temperatures:
- Thermostat failure testing with temperature controls shorted or opened
- Bunched blanket testing simulating improper use conditions
- Covered blanket testing preventing normal heat dissipation
- Continuous maximum setting operation for extended periods
- Single component failure scenarios
Products must incorporate fail-safe mechanisms preventing dangerous temperature rise even under these abnormal conditions.

Thermal Endurance Testing
Long-term reliability requires verification that products maintain thermal safety throughout expected lifespans. Accelerated aging tests subject electric blankets to thousands of heating cycles, extreme temperature variations, and mechanical flexing to simulate years of normal use.
