Glossary 71

KVA

The abbreviation for kilovolt-amperes. (1000 x 1 volt-amperes).

live load

The load that the floor system can safely support. Expressed in kg/m

(lb/ft

maximum input current

The operating current of the product equal to the maximum load divided by the minimum input voltage.

RMS

Root-mean-square (RMS) refers to the most common mathematical method of defining the effective voltage

current of an AC wave. To determine RMS value, three mathematical operations are carried out on the

function representing the AC waveform: 1) The square of the waveform function (usually a sine wave) is

determined. 2) The function resulting from step 1 is averaged over time. 3) The square root of the function

resulting from step 2 is found.

rolling load

The load a floor panel can support (without failure) when a wheel of specified diameter and width is

rolled across the panel.

ultimate load

The maximum load (per floor panel) that the floor system can support without failure, meaning floor

panels breaking or bending.

Ultimate load is usually stated as load per floor panel.

vapor seal

A vapor seal is an essential part of preventing moisture infiltration or migration out of a critical space,

such as a data processing center or other room that contains sensitive electronic instrumentation.

Essentially, a vapor seal is a barrier that prevents air, moisture, and contaminants from migrating through

tiny cracks or pores in the walls, floor, and ceiling into the critical space. Vapor barriers may be created

using plastic film, vapor-retardant paint, vinyl wall coverings and vinyl floor systems, in combination with

careful sealing of all openings (doors and windows) into the room.

watt

A unit of electricity consumption representing the product of amperage and voltage. When the power

requirement of a product is listed in watts, you can convert to amps by dividing the wattage by the

voltage (for example, 1200 W divided by 120 V is 10 A).
