Nanjing Market Supervision Administration will organize a VOC product (cleaning agents) quality supervision and sampling[1] in the following months. The implementation rules were made public on August 10, 2021. The deadline for sampling is October 30, 2021, and the deadline for inspection is December 1, 2021. The sampling quality analysis report shall be completed by December 10, 2021.
Commissioned by the Nanjing Market Supervision Administration, Jiangsu Institute of Product Quality Supervision and Inspection is responsible for sampling and inspection. The quantity of samples shall meet the inspection and backup requirements, with complete packaging and label, and with seals intact. The remaining validity of all samples shall not be less than 6 months.
The following table presents the locations and quantities of cleaning agent sampling:
Sampling location | Sampling batch | Number of samples per batch / number of samples left | Remarks |
Production businesses | 15 batches | 4 individual packages / 2 individual packages | The total amount of no less than 200g(mL) |
Nanjing physical stores | 10 batches | 4 individual packages / 2 individual packages | The total amount of no less than 200g(mL) |
Online stores registered in Nanjing | 5 batches | 4 individual packages / 2 individual packages | The total amount of no less than 200g(mL) |
Inspection items of cleaning agent include:
•VOC content
•The sum of the content of dichloromethane, trichloromethane, trichloroethylene and tetrachloroethylene
•Formaldehyde
•The sum of the content of benzene, toluene, ethylbenzene and xylene
•Packaging marks
The cleaning agent supervision and sampling is based on GB 38508-2020 Limit standard for volatile organic compounds content in cleaning agents (Chemlinked)[2], which was released on March 4, 2020, and implemented on December 1, 2020. This standard specifies the definitions, product classification, test methods and packaging marks requirements, and imposes limit requirements on VOCs content and some specific volatile organic compounds in the cleaning agents that affect the environment or human health.
In addition, the implementation rules detail the principles for VOC products quality inspection, objection handling and re-inspection. For example, if one or more items of the product inspected do not meet the standards specified in these rules, it is considered unqualified. More details can be viewed in the Annex[3].
