Product Overview
This blanket mechanical strength test apparatus is developed for evaluating the durability of flexible heating appliances covered by IEC 60335-2-17. During use, electric blankets and heating pads may be folded, pulled, moved or compressed repeatedly. These mechanical actions may affect the heating element, internal wiring, insulation layers and overall product structure.
The apparatus provides a repeatable mechanical movement setup for checking whether the sample can withstand the required test condition. It is not a general textile strength tester, and it is not used to perform electrical strength testing directly. Its role is to apply the mechanical strength procedure before further inspection or electrical safety verification is carried out according to the applicable test plan.
For manufacturers, this equipment helps identify structural weakness before formal certification testing. For laboratories, it provides a dedicated apparatus for IEC 60335-2-17 related blanket mechanical strength evaluation.
What This Equipment Tests
The apparatus is suitable for flexible heating appliances where repeated mechanical movement may influence product safety and durability.
Applicable Standard and Test Purpose
Applicable Standard
The apparatus is designed according to the mechanical strength test arrangement shown in IEC 60335-2-17 Figure BB.1 to BB.3 for blankets and similar flexible heating appliances.
Main Test Purpose
The test simulates mechanical stress that may occur during normal handling and use of electric blankets or heating pads, supporting development, pre-compliance evaluation and laboratory verification.
Testing Principle
The sample is installed on the apparatus and subjected to repeated mechanical movement through the driving sprocket and rotating drum structure. The 25° horizontal arm arrangement, rubber spheres and support components work together to reproduce the mechanical action required for blanket strength testing.
This procedure focuses on the complete product structure, rather than only the textile material. After the mechanical test, the tested product may need to be inspected or tested further according to the applicable IEC 60335-2-17 requirement and laboratory procedure.

Test Workflow
Confirm the Test Requirement
Confirm the applicable IEC 60335-2-17 version, test clause or figure reference, required cycle count and sample condition before testing.
Mount the Blanket Sample
Install the electric blanket, heating pad or flexible heating appliance on the apparatus according to the required test arrangement. Check that the sample is positioned correctly before starting the test.
Set the Test Parameters
Set the required number of cycles on the counter and confirm the mechanical settings, including the arm position, drum arrangement and sample support condition.
Start the Mechanical Strength Test
The driving sprocket and rotating drum apply repeated movement to the sample. The 25° horizontal arms, rubber spheres and support components reproduce the required mechanical action during the test.
Complete the Preset Cycles
The apparatus stops after the preset number of cycles is completed. The operator then removes the sample from the test position.
Inspect and Verify the Sample
Check the sample condition after mechanical testing. If required by the applicable test procedure, further inspection or electrical safety verification should be carried out using separate test equipment.
Difference from Related IEC 60335-2-17 Test Equipment
Mechanical Strength Test Apparatus
This apparatus applies repeated physical movement to the blanket sample to evaluate mechanical durability after simulated handling and use.
Spark Ignition or Electrical Strength Equipment
Spark ignition equipment is used for ignition-related safety evaluation, while electrical strength equipment is used for insulation or dielectric verification.
Compliance & Regulatory Assurance
- The Blanket Mechanical Strength Test Apparatus is designed for mechanical strength evaluation according to the selected IEC 60335-2-17 test scope, especially for electric blankets, heating pads and similar flexible heating appliances.
- The apparatus supports standard-based repeated movement testing through its 25° horizontal arm structure, rotating drum, rubber spheres and adjustable cycle control. The final test setting should be confirmed according to the applicable IEC, EN or GB standard version and laboratory test plan.
- This page should not be interpreted as a claim that one apparatus performs all IEC 60335-2-17 safety tests. For electrical strength verification, spark ignition evaluation or other safety checks, suitable separate test equipment should be selected according to the required clauses.
- Before order placement, customers are recommended to confirm the sample type, maximum blanket size, required cycle count, applicable clause or figure reference, power supply and documentation requirements. KINGPO can provide configuration support based on the submitted test requirements.
