The Declaration of Performance (DoP) for WISA plywood states the product’s exact technical properties. Up to date DoP documents are always available on UPM Plywood’s website.
The correct DoP document for WISA plywood can be conveniently found on UPM Plywood’s website using either the DoP search tool or the DoP reference list. The documents are available in PDF format in various languages. The easiest way to find the DoP document is with the DoP number in the product's CE mark.
Here's how to find the DoP number:
The DoP number can be found either on the plywood panel, on the pallet, or in the delivery documents, such as the invoice.
The CE mark contains a DoP number starting with the letter “UPM”, which is either stamped or affixed with a sticker on the product. All uncoated WISA plywood products usually have the CE mark printed on the panel.
With coated WISA plywood, the CE mark is printed on the pallet because the mark on the panel is covered by the coating or paint. The DoP number for coated plywood as well as certain panel sizes is available on the pallet and delivery documents only.
Here's how to find a DoP document:
1. If you have the DoP number for a WISA plywood product:
You can enter the DoP number in the search field at www.wisaplywood.com/dop.
2. If you don't have a DoP number:
The DoP document can also be downloaded from the DoP reference list, where products are listed by product type. Please note that the product type might have several DoP numbers depending on the panel thickness, use, structure or finish.
3. The most frequently searched DoP documents in each country are also available on the country specific WISA Plywood websites. For example, at wisaplywood.com/en-gb/, the list can be found at the bottom of the Good to Know> Specifying WISA plywood section:
