A quick test is to put a glass of water in the center of your room and bounce on your floor a couple times. If the water ripples there's movement which exceeds L/360. This isn't an accurate test ... it's simply a visual way to determine movement, and any movement should be considered a sign to investigate. If you provide the dimensions of your joists, spacing and unsupported span as well as subfloor description, the Forum Pros can assist you in our FORUM.

It's the maximum amount of deflection allowed in your floor. L/360 = unsupported span of joists in inches/360 For example: a floor joist which spans 10 feet with an L/360 limit is designed to deflect no more than 120"/360 = 1/3 inches under live loads. If you have a floor with joists over an unsupported span of 12' ... the floor should not deflect (bend downward) more than 5/16". See similar questions...

The humans subjects regulations decision charts from the Office of Human Research Protection (OHRP) will help you to see whether your research falls under the human subjects regulations and if so, whether it meets the criteria for Exemption 4.

The floor-to-floor height is the height of your stair. It reaches from the surface of the bottom floor to the surface of the top floor. It is NOT a floor-to-ceiling height. You may have plans that will help you calculate this amount, but it is advisable to measure once the floor s are installed --often homes are built slightly different than shown in the plans. You may be able to measure the distance through the open stairwell. See similar questions...

The downward movement of your floor when weight is applied. Deflection may occur along the span of your joists or in the plywood between your joists. Excessive deflection will cause your tile installation to fail. See similar questions...

A flexible pipe derives its soil load carrying capacity from its flexibility. Under soil load, the pipe tends to deflect (reduction of pipe diameter in the vertical direction), thereby developing passive soil support at the sides of the pipe. At the same time, the ring deflection re?lieves the pipe of the major portion of the vertical soil load, which is then carried by the surrounding soil through the mechanism of an arching action over the pipe.

In order to find this out, you must use a pin type meter with insulated contact pins. First, take several readings in the layer just below the surface; then make a series of core readings, closer to the center of the board thickness. After you have noted these readings, hammer the pins through the flooring material until you make contact with the sub floor. If your readings throughout this process are uniform, then there is not a moisture problem. See similar questions...
