| A steel alloy that forms a tenacious, self-protecting rust layer when exposed to the atmosphere.
|
| 1. Changes in color, texture, strength, chemical composition or other properties of a natural or artificial material due to the action of the weather. 2. The mechanical or chemical disintegration and discoloration of a wood surface resulting from exposure to light, action of dust and sand carried by winds, alternate shrinking and swelling brought about by changes in the weather or a combination of these causes; weathering does not include decay.
|
| A testing device intended to simulate atmospheric weathering.
|
| An electrical outlet or switch box which has been manufactured to withstand the outside elements.
|
| A protective layer constructed so that exposure to the weather will not interfere with successful operation.
|
| An enclosure for wires or cables constructed so that exposure to weather will not interfere with successful operation.
|
| A material used to rce heat transfer, constructed so that exposure to the weather will not interfere with its successful operation.
|
| A device designed to be used outdoors that opens, closes or changes the connection of an electric circuit and is weatherproofed against moisture.
|
| so constructed that exposure to the weather will not cause damage or loss of function.
|
| A ribbon of resilient material used to rce air infiltration through the crack around a sash or door.
|
| The process of rcing air or rain infiltration by covering joints of doors or windows with strips of resilient material.
|
| A type of weld bead made with transverse oscillation.
|
| Process of forming carpet on a loom by interlacing the warp and weft yarns.
|
| Commonly a used military type belt adapted to carry hand tools at the jobsite.
|
| The vertical and angular members between the top and bottom chords of a truss.
|
| 1. The vertical plate connecting the top and bottom flanges of a metal beam. 2. An interior solid portion of a hollow concrete block.
|
| A piece of material, such as wood or metal, tapering to a sharp edge that is driven between two objects or parts of an object to secure or separate them.
|
| The act or process of spraying chemicals or placing powders to control the spread of weeds.
|
| 1. A small opening, the purpose of which is to permit drainage of water that accumulates inside a building component. 2. Openings placed in mortar joints of facing material at the level of flashing to permit the escape of moisture. 3. Openings in retaining walls to permit water to escape.
|
| A plaster screed at the bottom of an exterior stucco wall that is designed to allow moisture to seep out.
|
| A masonry joint treatment in which mortar extruding from the joint in laying is not cut off, but is allowed to harden; gives informal rustic appearance but difficult to waterproof.
|
| Backing yarns which run across the width of the carpet; in woven carpets, the weft shot (filling) yarns and the warp chain (binder) yarns interlock and bind the pile tufts to the backing; in tufted carpets, pile yarns which run across the carpet are also considered weft yarns.
|
| The force experienced by a body as a result of the earths gravitation.
|
| The highest portion of the inside channel through a plumbing trap; compare with Dip of a Trap; the depth of the water seal is the distance from the dip to the crown weir.
|
| 1. A dam in a stream over which water flows; see Crest. 2. A dam in a stream to raise the water level or to divert the stream. 3. An orifice through which the liquid only partially flows.
|
| A weld deposit resulting from a pass.
|
| A crack in weld metal.
|
| Methods to determine existence and extent of defects and discontinuities in welds.
|
| A steel plate anchored into the surface of concrete, to which another steel element can be welded.
|
| Welding examination or inspection; the loading of welds to determine load capacity of welds is not normal practice.
