       Since the release of the "Volatile Organic Compound Content Limit Standard for Architectural Coatings and Adhesives" (hereinafter referred to as the "standard"), some companies still have doubts about the requirements of the standard content.
    Now, in response to the problems raised by the companies, the relevant standard content will be studied after a summary Interpretation.


    1.
    Issues concerning


    the scope of application of the standard This standard is mainly controlled by architectural coatings and adhesives.
    The goal is to control the content of volatile organic compounds in architectural coatings and adhesive products within the scope of application of the standard.
    For architectural coatings, This standard mainly controls several types of architectural coatings that are used in large quantities, including interior wall coatings, exterior wall coatings, waterproof coatings, floor coatings and architectural anticorrosive coatings.
    Architectural coatings that are not within the scope of the standard are not within the scope of control, but are not in the scope of control.
    Coating products (wall reinforcement, intermediate wall paint, etc.
    ) used for interior wall coatings, exterior wall coatings, waterproof coatings, floor coatings and architectural anticorrosive coatings need to refer to corresponding products and be included in control.


    1.
    Question: Does tile adhesive (powder), mortar, sbs adhesive, alkyd enamel, acrylic polyurethane enamel, epoxy topcoat, polyvinyl acetate, artistic paint, etc.
    comply with this standard?


    Answer: For products with different names and types, first determine whether they are used in the construction field according to their intended use.
    All coatings used in the construction field (including exterior wall coatings, interior wall coatings, waterproof coatings, floor coatings and architectural anticorrosive coatings) And adhesives (including solvent-based adhesives, water-based adhesives and bulk adhesives) are applicable to this standard.
    For coatings and adhesives used in the construction field, the classification should be judged according to the product type in the standard (standard table 1), and the content limit and detection method should be determined.


    Coatings and adhesives that are only used in the industrial field (such as: used in the furniture production process of furniture enterprises) are not within the control scope of this standard.


    2.
    Question: How to define anti-corrosion coatings for buildings?
    How to determine which projects in Beijing need to apply heavy-duty coatings?


    Answer: The paint that can delay or prevent the corrosion of building materials is called building anticorrosive coating.
    The paint suitable for home improvement, public environment, building concrete and steel structure surface protection and decoration belongs to building anticorrosive coating.
    The decision whether to use heavy-duty anti-corrosion coatings should be based on the anti-corrosion grade specified in the design documents.


    2.
    Product packaging labeling issues


    This standard puts forward mandatory packaging labeling requirements for architectural coatings and adhesives.
    The goal is to guide consumers to choose products with low VOC content, and at the same time provide a basis for law enforcement by administrative departments.
    The enterprise can choose the expression of the supplementary content of the packaging mark, but it must include all the content of the supplementary marking of the packaging mark specified in Standard 7.
    1.


    1.
    Question: Can products manufactured before September 1 (standard implementation date) be supplemented with existing labels?
    How should the label be added?


    Answer: Starting from September 1 (standard implementation date), all products produced, sold and used in Beijing shall be implemented in accordance with the requirements of the standard.
    Products produced and in circulation before September 1, as long as they are still sold and used in Beijing after September 1, should comply with the requirements of the standard, and the content limits and packaging marks must meet the requirements of the standard.


    Product packaging marks should be in the form of changing the original packaging design and adding standard requirements.
    For products produced before September 1, if it is too late to change the packaging marks, the existing labels can be added in the form of supplementary labels to add standard requirements.


    The supplementary label requirements must include the content specified in Standard 7.
    1, and the supplementary label form is not specifically limited (such as: pasting, printing, etc.
    ), but it must be ensured that the supplementary label is easy to query, not easy to fall off, and the content is clear and identifiable.


    2.
    Question: What content is required to be added to the packaging label in the standard?


    Answer: According to the provisions of Standard 7.
    1, the added packaging mark must have:


    ①Product type.
    According to the classification in Table 1 of the standard, the requirements can correspond to the sub-categories in Table 1 [such as: exterior wall paint-finish paint; interior wall paint-finish paint-gloss (60o≤10)]; usually the product type in the packaging label should be Distinguish from the product name.
    If the product name can indicate the product type, the product name should meet the above-mentioned requirements for product type expression.
    At the same time, the product name should be named according to the true and accurate attributes of the product and meet the requirements of corresponding laws, regulations, and standards.


    ②Product usage.
    It is required to refer to Appendix A of the standard and write clearly its use.
    For coatings and adhesives with a wide range of applications, it is required to write its use in the field of construction;


    ③The content of volatile organic compounds contained in the product.
    Refer to Appendix A of the standard, the expression form should be: volatile organic compound content X g/L, or volatile organic compound content ≤ X g/L (X is the specific content value, that is: the content value must be clearly written); it is prohibited to use " "Volatile organic compound content is less than the detection limit", "Volatile organic compound content meets standard requirements", "Volatile organic compound content is not detected" and other expressions; "Volatile organic compound content" can be abbreviated as "VOC content".


    ④Dilution solvent and dilution amount (products that need to be diluted during construction).
    Refer to Appendix A of the standard, write down the recommended diluent name and dilution ratio; the specific content of the label should correspond to the product type, if some products do not have recommended diluent, it does not need to be reflected on the packaging label, that is, the "/" part does not need to be reflected For example, water-based paints and water-based adhesives do not need to indicate the recommended diluent and the amount of dilution.


    ⑤ Construction ratio (two-component or multi-component accessory product).
    Reference standard Appendix A adopts the expression "component A: component B=1:X".


    In summary, the label content should try to adopt the form in the standard appendix A.
    If the form cannot be expressed in appendix A, the above requirements should be reflected as much as possible to facilitate the search for benchmarking.


    3.
    Question: Are there any requirements for label font size, color, typesetting and other formats?


    Answer: There are no unified requirements for the label font size, color, typesetting and other formats, but the expression should be easy to identify, and should comply with the "Product Quality Law of the People's Republic of China" (Chairman Order No.
    71), "Instructions for Use of Consumer Products Part 1 General Provisions" "(GB/T 5296.
    1-2012) and other laws, regulations, and standards.
    For specific marking methods, please refer to "Product Marking Regulations" (Technical Supervision Bureau Jianfa [1997] No.
    172).


    4.
    Question: How to label products such as suits and experience packages?


    Answer: Both the suit and the experience package require that the minimum sales unit shall be implemented in accordance with the requirements of this standard.
    If the surface area of ​​the product is too small and there is no place to add standard requirements, it can be implemented in accordance with the provisions of the "Instructions for Use of Consumer Products Part 1 General Rules" (GB/T 5296.
    1-2012) (provide standard requirements and identification content information on the instructions), but must Make sure that the contents of the manual are not separated from the product packaging.


    3.
    Product testing issues.


    This standard sets requirements on the limits of volatile organic compounds in products.
    Enterprises can entrust a qualified testing agency to conduct testing, or they can purchase testing equipment for testing.
    Both forms require that they be tested in accordance with the standard.
    The specified inspection method is tested.


    Ex-factory products shall not only comply with the provisions of this standard, but also comply with the requirements of relevant national standards and industry standards.
