241 WASH COAT:
 
A coating that is used to seal wood surfaces, preventing undesired staining, and control penetration. For the purpose of this rule, washcoats shall be considered low-solids coatings and shall contain less than 454 grams (1 pound) of solids per 3.785 liters (1 gallon), by weight. Wash coats with greater than 454 grams (1 pound) of solids per 3.785 liters (1 gallon), by weight, shall be considered sealers.
 
242 WOOD PANEL:

243 WOOD PRODUCTS:
 
Surface-coated products which include cabinets (kitchen, bath, and vanity), tables, chairs, beds, sofas, shutters, art objects, and any other coated objects made of solid wood, and/or wood composition.
 
244 WOOD PRODUCT COATING APPLICATION OPERATIONS:
 
A combination of coating application steps which may include use of spray guns, flash-off areas, spray booths, ovens, conveyors, and/or other equipment operated for the purpose of applying coating materials.

401 PRODUCT INFORMATION REQUIREMENTS FOR SELLERS:

402 CALCULATION FOR DETERMINING VOLATILE ORGANIC COMPOUND COMPOSITE PARTIAL VAPOR PRESSURE:

403 CALCULATION FOR DETERMINING WEIGHT OF VOC PER VOLUME OF COATING, LESS WATER AND LESS EXEMPT COMPOUNDS: The volume of coating material is defined as the volume of the original coating, plus any VOC-containing material added to the original coating. The weight of VOC per combined volume of VOC and coating solids, shall be calculated by the following equation:

 

 Where:

404 CALCULATION FOR DETERMINATION OF VOC CONTENT PER VOLUME OF MATERIAL: The volume of material is defined as the volume of the original material, plus any VOC-containing material added to the original material. The original material is the material before any VOC-containing material such as solvent is added for purposes of mixing or thinning. The VOC content shall exclude any colorant added to a tint base. The weight of VOC per total volume of material shall be calculated by the following equation:
