Standards
Laminated glass standards explained: IS 2553, EN 14449, ANSI Z97.1
Laminated safety glass is certified as a finished laminate, not as interlayer film. IS 2553 Part 1 governs in India, EN ISO 12543 and EN 14449 in Europe, ANSI Z97.1 and CPSC 16 CFR 1201 in North America, and AS/NZS 2208 in Australia and New Zealand.

What the tests actually measure
Across regions the core test is broadly the same: a defined mass is dropped from a defined height onto a mounted panel, and the panel must either resist penetration or break in a way that leaves fragments retained by the interlayer.
What differs is the impact energy classes, the mounting conditions, the tolerance for detached fragment mass, and the additional durability tests — high temperature, humidity and radiation exposure — that check the laminate does not degrade in service.
Because those durability tests exist, interlayer quality and lamination process control both show up in certification results. A laminate that passes impact but fails humidity exposure usually points to interlayer moisture control rather than to the impact design.
What to ask an interlayer supplier for
- Material specification with the properties that govern lamination — thickness tolerance, adhesion grade, moisture content, haze.
- Batch test data for the consignment being supplied, not a generic datasheet.
- Evidence of suitability for the standard you certify to, and any third-party test reports available.
- Storage and handling requirements in writing, since these directly affect whether your laminate passes.
- Batch traceability, so a failed test can be traced back to material rather than guessed at.
Frequently asked questions
Can an interlayer supplier certify my laminated glass to IS 2553?
No. Conformity applies to the finished laminate produced on your line, so certification is obtained by the processor testing their own product. The interlayer supplier supports that with material specifications, batch test data and evidence of suitability.
Does CE marking apply to laminated glass exported to Europe?
Yes. Laminated safety glass placed on the European market requires CE marking under EN 14449, with conformity evaluated against EN ISO 12543. This is obtained by the manufacturer of the finished laminate.
Which standard applies for a project in the UAE or Saudi Arabia?
Gulf projects commonly specify to European (EN) or American (ANSI/ASTM) standards depending on the consultant, with local authority requirements layered on top. Confirm the governing standard from the project specification rather than assuming a regional default.
