Special requirements for IEC 60335-2-59 and GB4706.76 standard insect killers: Detailed explanation of test requirements

With the continuous development of the household appliance market, product safety has become the focus of both consumers and manufacturers. As an important guide for safety testing of household appliances, the latest version of the standard specifies in detail the safety requirements for equipment such as insect killers. Today, we will focus on the testing requirements in Chapter 22 of the standard to help manufacturers ensure the safety compliance of their products.

22.6 Drain hole dimensions

Keyword analysis:

1. Drainage hole: refers to the small hole on the device used to drain internal water.

2. Diameter should be at least 5mm: Make sure the size of the drainage hole is sufficient so that water can drain smoothly.

3. The area should be at least 20mm²: the total area of drainage holes should reach a certain standard to ensure drainage efficiency.

4. Width of at least 3mm: The width of the drainage hole should also meet the minimum size requirements to prevent clogging.

Test Methods:

Check that the drain hole size complies with regulations by observation and use of an IEC 61032B type test rod.

22.101 Interlock switch

Keyword analysis:

1. Interlock switch: A safety device used to prevent user access to live parts during maintenance.

2. Input circuit: refers to the circuit part where power enters the device.

3. Prevent accidental operation: Ensure interlock switches are located and designed to avoid accidental contact with live parts during maintenance.

Test Methods:

Verify that the interlock switch effectively prevents accidental contact by observing its position and function and using an IEC 61032B type test rod for inspection.

22.102 Grid grounding

Keyword analysis:

1. Horizontal form grille: refers to the ventilation or protective grid structure on the equipment.

2. One pole of the output terminal of the transformer is connected to an easily accessible component: This means that the output terminal of the transformer may be connected to a component that is easily accessible to the user.

3. The lowest grille is grounded: This means that the lowest grille on the device needs to be connected to the ground wire to reduce the risk of electric shock.

Test Methods:

Verify by visual inspection that the lowest grille is grounded.

22.103 No risk of electric shock

Keyword analysis:

1. Appliance structure: refers to the overall design and structure of the insect zapper.

2. Access to the grille during maintenance: refers to the parts of the grille that may be touched during maintenance.

3. No risk of electric shock: Make sure that touching the grille during maintenance will not cause electric shock.

Test Methods:

The appliance is powered at rated voltage. 1 second after disconnecting the power supply, use an instrument that does not affect the measurement value to measure the voltage between the grids to ensure that the voltage does not exceed 34V.

22.104 Short circuit current

Keyword analysis:

1. Output circuit: refers to the circuit from the power source to the load (such as the heating element of a bug zapper).

2. Short circuit current: The current that flows when a short circuit occurs in a circuit.

3. It should not be too large: it means that the size of the short-circuit current should be within a safe range to prevent equipment damage or fire.

Test Methods:

Power supply at rated voltage, measure the short-circuit current between the two grids and each grid to ground to ensure that the short-circuit current does not exceed 10mA.

The purpose of these testing requirements is to ensure that the zapper meets safety standards during design and manufacturing to protect users from electrical hazards. Manufacturers should ensure that their products meet these safety requirements during design and production.

Conclusion: Chapter 22 of the standard provides clear testing guidance for manufacturers of household appliances to ensure the electrical safety of their products. Manufacturers should strictly comply with these requirements and provide consumers with safe and reliable household appliances through precise testing and quality control.

Bluetooth certification is also BQB certification. In short, if your product has Bluetooth function and the Bluetooth logo is marked on the product appearance, it must pass BQB certification. Bluetooth certification is a certification process that any product using Bluetooth wireless technology must undergo. Bluetooth wireless technology defined in the Bluetooth System Specification allows short-range wireless data connections between devices.

Products with Bluetooth functionality and a Bluetooth logo marked on the product appearance must pass Bluetooth BQB (Bluetooth Qualification Body) certification.

Standard reference
The Bluetooth Certification Program Reference Document is the standard reference for the product certification process.
Members of the Bluetooth Special Interest Group have a royalty-free right to use Bluetooth wireless technology in product listings on the Bluetooth Qualified Product List (QPL). Bluetooth SIG membership is free.
The Bluetooth QPL lists all licensed Bluetooth products, subsystems, components and development tools. Products listed in the QPL are specifically authorized by Bluetooth Qualification Bodies (BQBs) located around the world. Any BQB can evaluate, certify, and list any product for certification. Joining BQB early can minimize product development time and costs.

The Bluetooth Product Certification Guidelines, documented in the PRD, are developed by the Bluetooth Certification Evaluation Board (BQRB), which is elected by representatives from the nine Bluetooth SIG sponsoring companies. The certification process is handled by the Bluetooth Certification Administrator (BQA) who represents the interests of the BQRB.
BQRB recognizes individual Bluetooth Qualification Bodies (BQBs) and authorizes them to certify and list products. The BQRB also recognizes Bluetooth Qualified Test Facilities (BQTFs) that have been qualified to perform and report Class A test results (see the Certification Process Description for more detailed information). BQRB also accredits Bluetooth technology estimators, who evaluate and recommend BQTF candidates.

The Bluetooth Qualification Testing Agency (BQTF) is officially recognized by the BQRB and can complete the "Class A" Bluetooth certification conformance test identification in the Test Case Reference List (TCRL). BQTF corner
