## Is this an EU-certified or legally registered DPP?
Source: https://zbcarbon.com/knowledge/product-passports/faq.en.md

No. These are voluntary catalogue-model preparation records. Product-specific legal applicability, conformity and EU registry registration have not been established. An internal passport URL is not a registry identifier.

## Can I use a listed number as a guaranteed specification?
Source: https://zbcarbon.com/knowledge/product-passports/faq.en.md

Legacy values show what a historical page or catalogue listed. Confirm the exact model, measurement object, tolerances, test method and conditions before procurement or engineering use.

## Does fibre strength prove the strength of a tube or sheet?
Source: https://zbcarbon.com/knowledge/product-passports/faq.en.md

No. Raw fibre, fabric, prepreg, cured laminate, finished component and installed system results apply to different test objects. Request evidence for the supplied product and load case.

## How do I request a current specification or test report?
Source: https://zbcarbon.com/knowledge/product-passports/faq.en.md

Send the product URL, required dimensions or model, intended use, process and acceptance criteria to sales@zbcarbon.com. Request the matching TDS, safety information or batch certificate as applicable.

## Which appearance options are confirmed for the glass-fiberglass ceiling-board page?
Source: https://zbcarbon.com/knowledge/product-passports/faq.en.md

A company-supplied statement dated 12 November 2026 confirms plain white and white-speckled/yellow-backed appearance options can be supplied. This confirms appearance only; construction, dimensions and performance still require model confirmation.

## Do all product images show a photographed, tested production item?
Source: https://zbcarbon.com/knowledge/product-passports/faq.en.md

No. The website uses existing catalogue imagery, technical renderings and disclosed AI-assisted illustrations. Images do not verify material grade, resin state, internal construction, performance or certification. Some UD images illustrate the category rather than an exact SKU.

## Is coated E-glass automatically the same as AR glass?
Source: https://zbcarbon.com/knowledge/product-passports/faq.en.md

No. Confirm the base glass composition and, where relevant, zirconia content, coating, conditioning method and retained strength for the selected model.

## Does a catalogue entry confirm current stock, price or delivery time?
Source: https://zbcarbon.com/knowledge/product-passports/faq.en.md

No. Model availability, price, minimum quantity, samples and lead time require a current quotation for the selected specification.
