The plan for quality supervision spot checks on e-cigarette products sold in Shenzhen in the second half of 2024.

Sampling method

By randomly sampling, 75 smoking accessories and compatible pods (or combination products) of each type are selected, as well as at least 80 grams of aerosolized material, divided into test samples and backup samples as required. Test samples are sent to the relevant testing institution, while backup samples are temporarily stored at the institution responsible for sampling and used as needed for spot checks. The sampling form can be found in Appendix 1.

2. Examination criteria

Judgment Rules

Based on standards.

GB 41700 refers to an e-cigarette product.

3.2 Judgment principle

After conducting tests, it was found that all tested items met the standard requirements, determining the randomly sampled products to be compliant. If any item in the test does not meet the standard requirements, the randomly sampled product is considered non-compliant.

4. Conclusion

This scheme is applicable for quality supervision spot checks on e-cigarette products sold within Shenzhen city in the second half of 2024.
