Wood flooring is not required to meet specific hardness standards because each wood species has unique features and hardness.
Hardness is measured on the Janka Hardness Scale. The Janka hardness test measures the amount of force required to push a steel ball with a diameter of 11.28 millimeters (0.444 inches) into the wood to a depth of half the ball's diameter. The result is expressed in pounds-force (lbf). If you're installing a floor in a high traffic area or you have large pets, you'll want to look at a floor with a higher Janka hardness rating because a higher hardness rating means that the floor will be more resistant to scratches, dents, and other types of damage. However, hardness isn't the only factor that goes into the durability of a floor. Other factors are the type of finish used, the amount of gloss, the number of coats, and even the grain of the wood. It's important to understand that while hardwood floors are tough, when it comes to indentations NO FLOOR is impervious to damage. The standard in the wood flooring industry is measured by comparing a given species hardness to white oak, which has a Janka rating or 1360. By comparing to domestic white or red oak you can tell how hard or soft a floor is. For species like Santos Mahogany (Janka rating 2200) or Brazilian Walnut aka Ipe (Janka rating 3680) which feature far denser grain patterns, and are thus harder and more resistant to some damage than species like North American Cherry (Janka rating 950) or Black Walnut (Janka rating 1010).
Yes, if it is a floating hardwood floor. You can find them as click together or where the seams are glued. The downside is that often these floors are hard to repair unlike a solid wood floor. But if you want real wood and have concrete you do have options. Don't forget the foam padding required for all these floors.
There are no standards required "for" ISO 9001-2008, The ISO standards ARE the standards (relating to quality).

Floating an engineered wood flooring is done using an underlay between the sub floor and the new floor and then the engineered flooring is laid over the top and glued at the tongue and grooves to keep it together. if the flooring is a click joint then gluing is not required.

Sure you can refinish your hardwood floors. The task itself isn't a difficult one in the sense of skill required. It's difficult because of the hard work, and patience required. All you do is sand them down and apply your stain finish.
The purpose of a National Vocational Qualification is to award a specific type of employment if it meets the required standards. These standards are based on the National Occupational Standards.
