| MOQ: | 1 |
| Price: | To be quoted |
| Standard Packaging: | safety carton pack or plywood box |
| Delivery Period: | 25 working days |
| Payment Method: | T/T |
| Supply Capacity: | 3 sets per month |
| Equipment | Specification Requirements |
|---|---|
| Dynamic Cyclic Test Machine | Lift stroke ≥ 305 mm, lift time ≤ 1 second, cycle frequency 1 cycle/second, max load ≥ 60 kg |
| Clamping Device | Width 51–102 mm (adjustable), centered on gripping area, equal load for multiple handles |
| Weighing System | Resolution 1 g, accuracy ±0.1% |
| Temperature Control System | Maintain Clause 41 highest handle temperature ±5°C |

| Item | Requirements |
|---|---|
| Sample Quantity | 6 units (3 units for 58.5 high-temperature energized test, 3 units for 58.6 ambient unenergized repeat test) |
| Pre-treatment | Weigh each unit independently: base + lid + vessel + full water (overflow capacity) → total weight × 3 |
| Separate Cooking Vessel Test | Vessel + full water (overflow capacity) × 3 |
| Energized Preheating | Operate per Clause 41.1.14 at highest handle temperature setting until thermally stable (≥2 hours) |
5. Test Procedures (Corresponding to UL Original Article by Article)
6. Acceptance Criteria
| Item | Pass Criteria |
|---|---|
| Handle Integrity | No breakage, separation, or permanent deformation |
| Deformation Amount | ≤ 5 mm (visual + vernier caliper) |
| Force Attenuation | Throughout ≤ 10% |
| Electrical Safety | No insulation damage or grounding failure |
| Cycle Completion | 5000 cycles without failure |
Q1: Why is the cycle count 5000 times instead of 50,000 times?
A: UL 1026 Clause 58.5 explicitly specifies 5000 cycles (not 50,000). Early versions or misreading of IEC 60335-2-15 may cause confusion. This specification follows the UL 1026 original text.
Q2: Is separate testing required for lid handles?
A: No. 58.3 and 58.4 only target heating base handles and separate cooking vessel handles. If lid handles are auxiliary grips, they are included in the base test load.
Q3: Can the gripping width be less than 51 mm?
A: Yes. The original text allows: “Due to limitations of handle design, a smaller width gripping area may be used.” Record the actual width and archive photos.
Q4: How to distribute load for multiple handles?
A: Proportionally evenly divide the total weight, ensure balanced force on each handle, maintain overall center of gravity unchanged.
Q5: In high-temperature testing, how to maintain “highest handle temperature”?
A: First perform Clause 41 normal temperature test, record highest stable temperature for each handle. In 58.5 test, energize and operate under the same setting, monitor handle temperature in real-time, use insulation cover if necessary to maintain ±5°C.
Q6: How to achieve the “3 times full load” test load?
A: Use water + counterweights or dedicated load simulator. Count each gram of water as 1 g weight, align counterweight centers with original center of gravity.
Q7: Is video recording required?
A: Strongly recommended. Especially record the 1st, 2500th, and 5000th lift processes for failure analysis.
Q8: Can the samples after high-temperature test (58.5) be used for ambient test (58.6)?
A: No. 58.6 explicitly requires “a separate sample”, must use brand new samples.
