Composite Wood - "100% not covered by other categories"

If you check low emitting calculator, you will find that composite wood needs to be 100% compliant. "100% not covered by other categories" may be written because composite wood can also comes under Furniture or flooring or ceiling category as well, where criteria of compliance is different to that of composite wood.

So, from my understanding this line means, if you're targeting composite wood category, you have to meet 100% compliance even if it is compliant with any other category, like furniture, flooring.  

I believe that a composite wood product that is not considered flooring, ceiling, walls or furniture that is painted on site would have separate criteria for the composite wood and the site-applied coating. See Table 5 for what each category includes.

The reference in the chart to composite wood "100% not covered by other categories" refers to the fact that many composite wood products fall under the flooring, ceiling, walls and furniture categories. Products in these categories have to meet the General Emissions Evaluation or Furniture Evaluation (as applicable, per the chart), instead of the Composite Wood Evaluation. Composite wood products that don't fall into another category, have to meet the Composite Wood Evaluation.
