On site, "delam" gets used for almost any panel that looks like it is coming apart. In the standards, plywood delamination is narrower: a visible separation between plies at a glue line that should have been bonded in the press. Film peeling and veneer checks are different failures, and naming the right one is where a fair quality claim starts. This episode is informational only — not legal advice and not a commercial offer.

What You'll Learn

• How the standards define delamination — and why splits, checks and broken grain in the wood do not count
• Four symptoms site crews call "delam" and what each usually points to: core glue line, press fault, overlay bond or veneer checking
• Why glue lines let go: wet-dry cycling, a bond class mismatched to exposure (UF vs MUF vs phenol-formaldehyde) and under-cured pressing
• How EN 314-1 pretreatments (24-hour cold soak through 72-hour boil) and shear tests feed EN 314-2 Classes 1, 2 and 3
• What "wood failure" means, and how PS 1 Exposure 1 and Exterior thresholds compare for North American buyers
• Why film-faced formwork carries two bonds, core and face, and why edges usually fail first
• A buyer checklist: bond class, pretreatment, actual shear and wood-failure numbers, edge seal, lab name and test date

Key Standards / Data Discussed

• EN 314-1 (plywood bonding quality — test methods and pretreatments)
• EN 314-2 Bond Classes 1, 2 and 3 (dry, humid, exterior)
• PS 1-22 structural plywood (Exposure 1 and Exterior bond requirements)
• APA bond classifications (moisture resistance of the bond, not panel strength)
• WBP as trade shorthand (water-resistant, not water-immune)

Importers who only see the word "phenolic" on a packing list are reading compressed trade talk. Phenolic plywood can mean a phenol-formaldehyde glue line, a phenolic film face for formwork, or both — film gsm is not a glue class, and Class 3 glue is not a formwork film. This episode is informational only — not legal advice and not a commercial offer.

What You'll Learn

• Why one "phenolic" RFQ can return three incompatible quotes until each layer is named
• How a phenol-formaldehyde glue line maps to EN 314-2 Bond Class 3 (when tested and declared) — and why "WBP" alone is weak audit language
• What a phenolic paper film face is for (release, finish, face protection) and why film gsm does not prove Class 3 in the core
• How to read glue-only vs film-face vs film-plus-Class-3 rows on the packing list and certificate
• What phenolic is not: absolute waterproof marketing, melamine kitchen laminate language, P-Form polypropylene face talk, or a marine class by itself
• A practical PO rewrite: glue class and film face as separate cost drivers before deposit

Key Standards / Data Discussed

• EN 314-2 Bond Class 3 (exterior glue path)
• WBP as trade shorthand (not a substitute for the class number)
• EN 636 type/service language when construction placement applies
• BS 1088 (marine — only when that standard is on the PO)
• HDO / MDO / shuttering / film-faced as regional face vocabulary

Market data, pricing estimates, transit times, and standards references in this episode are based on information available as of September 2026. Figures are indicative and may not reflect current market conditions.

Importers who only see the word "marine" on a packing list are reading marketing. BS 1088:2018 is the current British Standard for marine plywood: two classes (standard and lightweight), Bond Class 3 under EN 314-2, and a stamp-versus-certificate filter. This episode is informational only — not legal advice and not a commercial offer.

What You'll Learn

• Why BS 1088:2018 replaced the withdrawn 2003 parts, and why a "BS 1088-1:2003" stamp is a claim to verify
• How standard vs lightweight classes split by density (around 500 kg/m³ at 12% MC) and EN 350 durability pointers — without changing the Bond Class 3 glue regime
• Why Bond Class 3 / EN 314-2 Class 3 belongs on the purchase order, and why "WBP" alone is weak audit language
• What BS 1088 does not cover: structural design values, site edge-wetting behaviour, and EN 13986 / CE as a separate construction route
• A practical importer checklist: edition year, class name, bond method, matching legal names, and batch-tied reports
• How CE/EN 13986, IS 710, and Vietnam plantation species lines sit beside a BS 1088 claim

Key Standards / Data Discussed

• BS 1088:2018 Marine plywood — Requirements
• BS EN 314-2 Bond Class 3
• BS EN 350 natural durability framing
• BS EN 13986 / CE (construction placement — parallel, not synonym)
• IS 710 (India marine / BWP — not a drop-in substitute)
