JC/T 2166-2013 Polyvinyl butyral (PVB) interlayer for laminated glass
1 Scope
This standard specifies the terms and definitions, product classification, technical requirements, test methods, inspection rules, as well as marking, packaging, transportation and storage of polyvinyl butyral (PVB) interlayers for laminated glass.
This standard is applicable to polyvinyl butyral (PVB) interlayers for laminated glass in buildings and automotive laminated glass. It may serve as a reference for interlayers for other types of laminated glass.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
crystal particle
colorless or slightly yellowish, transparent, crystal-like dotted substance with uneven optical density inside the interlayer, which is usually formed in the melt due to uneven melting of raw materials or during cooling and setting of additives
3.2
ripple
linear mark on the product surface caused by fluctuations of cooling water surface during interlayer production
3.3
bubble
bubble-shaped gas which fails to be fully removed and is trapped inside the product during interlayer production
3.4
burnt point
point that turns yellow or black due to decomposition during interlayer production
3.5
impurity
other visible substance that is entrained in the interlayer product but is incompatible with it
3.6
oil drop
point-like oil stain present on the interlayer surface
3.7
bead
tear-shaped drip adhering to the product surface
4 Product classification
4.1 According to the nominal thickness, the products are classified into interlayers with a nominal thickness of 0.38mm, 0.76mm, and 1.52mm, respectively.
4.2 According to the color, the products are classified into colorless interlayers and colored interlayers.
4.3 According to the application, the products are classified into architectural interlayers and automotive interlayers.
