Note – When using this standard, it is advisable to check the validity of the reference standards using the “National Standards” index compiled as of January 1 of the current year, and according to the corresponding information indexes published in the current year. If the reference standard is replaced (changed), then when using this standard, you should be guided by the replacing (changed) standard. If the reference standard is canceled without replacement, then the provision in which a reference is made to it is applied in the part that does not affect this reference.

3.1 Facing material is manufactured according to the following types:

A
– decorative and primer films based on papers impregnated in urea-formaldehyde or urea-melamine-formaldehyde impregnating resins, intended for lining panel furniture parts with subsequent finishing with nitrocellulose, polyester varnishes, acid-curing varnishes, nitro- and polyester enamels;

V
– decorative films based on papers impregnated in urea-formaldehyde resins, modified with polyester emulsions, intended for lining panel furniture parts with subsequent finishing with polyester varnishes;

C
– decorative and primer films based on papers impregnated in adhesive urea-formaldehyde resin, intended for lining panel furniture parts with subsequent finishing with nitrocellulose varnishes and enamels;
