The qualitative classification complies with the requirements of UNI EN 635-2. Ayous plywood panels with poplar internal layers are usually produced by classifying them by surface appearance as belonging to Classes II/III (corresponding to UNI 6469-69 Classes B/BB). Other classifications can be supplied upon request.

	Class II (formerly Class B under UNI 6471) “Natural” surface, with chromatic changes and sound knots, suitable for coatings with rolled section, pigmented varnishes or lacquer. Adherent sound knots are allowed up to a 35 mm diameter, as well as small deciduous knots or cracking. Moreover, low contrast colourings, occasional adhesive stains, well done repairs and stuccoes are allowed too.
	Class III (formerly Class BB under UNI 6471) “Open” surface, stuccoed upon request, suitable for non visible uses. Adherent sound knots are allowed up to a 50 mm diameter; as well as deciduous knots, cracking, bark inclusions and overlapped parts. Colourings are allowed, provided that they are sound, as well as adhesive stains, repairs and stuccoes of any extent.

The bonding quality

Ayous plywood can be manufactured with the following types of adhesive:

• Class 1: for use in dry environments (dry indoors) pursuant to UNI EN 314, urea adhesive.
• Class 2: for use in humid environments (sheltered outdoors) pursuant to UNI EN 314, melamine-urea adhesive
• Class 3: for outdoor use (unsheltered outdoors) pursuant to UNI EN 314, melamine-urea adhesive
