Compliance-Überblick

Dieser Überblick ist derzeit nur auf Englisch verfügbar.

Geltungsbereich und Anwendbarkeit

This standard applies to adhesives specifically manufactured and labeled for footwear and case and bag applications. It covers bonding performance, hazardous substance limits, and corresponding test methods. It is important to note that this standard does not apply to special functional surface treatment agents used during the bonding process of shoe and bag materials.

Technische Anforderungen

The standard specifies two main categories of technical requirements: bonding performance and hazardous substance limits. For footwear adhesives, it defines metrics such as initial tack, peel strength, heat aging resistance, shear strength, and creep. For case and bag adhesives, it primarily mandates a minimum peel strength. These bonding performance requirements are mandatory for normal wearing conditions, though special footwear like safety or sports shoes may require additional testing. The hazardous substance limits are strictly regulated, particularly in Section 3.4, which is a mandatory clause. It sets strict maximum limits for toxic chemicals such as benzene, toluene, xylene, free toluene diisocyanate, n-hexane, and halogenated hydrocarbons. Compliance with these chemical limits is essential for market access. The standard distinguishes between solvent-based and water-based adhesives, applying different regulatory thresholds to each. For instance, water-based adhesives have specific limits for total volatile organic compounds (VOC), and a dedicated method is provided for water-based polyurethane adhesives. Appendix D specifically regulates the VOC determination for these water-based formulations.

Prüfverfahren

Bonding performance is evaluated using standardized peel and shear tests, referencing methods like GB/T 532-2008 and GB/T 7124-2008. Creep resistance is tested using a creep method at elevated temperatures. Chemical safety is assessed via gas chromatography for solvents like n-hexane and halogenated hydrocarbons, while Karl Fischer titration is used to determine water content for VOC calculations. Manufacturers must ensure their testing materials and processes align with these specified protocols.

Häufige Fragen

What products are regulated under GB 19340-2014?

The standard regulates adhesives specifically labeled and used for footwear and case and bag manufacturing. It does not apply to special functional surface treatment agents used during the bonding process of these materials.

Are there any updates from the previous version of GB 19340-2014?

The 2014 version updates the scope, modifies the hazardous substance limits, and revises the testing appendices. It also introduces new appendices for recommended bonding test materials and a specific determination method for total VOC in water-based polyurethane adhesives.

How does GB 19340-2014 differ from ISO standards?

While it references international testing principles, it sets specific Chinese national limits for hazardous substances like benzene, toluene, and halogenated hydrocarbons. Manufacturers must test according to the specified GB methods to demonstrate compliance rather than relying solely on ISO certifications.
