How much fabric width is required to create drapery with a fullness of 150%?
A. 2 times the finished fabric width
B. 1.5 times the finished fabric width
C. 3 times the finished fabric width
D. 2.5 times the finished fabric width
D. 2.5 times the finished fabric width
Explanation: The fullness of drapery is a measure of how much of the fabric is taken up in pleating.
The fullness of drapery is the width of the drapery when it is sewn and pleated together. For example a 48” wide width of fabric will pleat down to a finished width of 16-24” depending upon how the fullness desired.
There are 3 standard fullnesses used for drapery:
2: 1, 2 to 1 or 100%
2. 5:1 2.5 to 1 or 150%
3: 1 3 to 1 or 200%
What most affects the flammability of upholstery?
A. Type of chemical retardant used
B. Surface fabric and interliner
C. Surface fabric
D. Cushioning and surface fabric
D. Cushioning and surface fabric
Explanation: Although chemical retardants and interliners are important considerations in upholstery flammability resistance, the combination of surface fabric and cushioning has the greatest effect.
216 pitch carpet has:
A. A commercial-grade stitch rate
B. 8 surface yarns per inch
C. An equivalent gauge of 1/6
D. A pile height that is almost 1/4 in high
B. 8 surface yarns per inch
Explanation: Pitch is the number of ends of surface yarn in a 27 in width. To convert this measurement to gauge (the spacing between stitches) divide 27 inches into 216 stitches. This gives 8 stitches/in, or 8 surface yarns/in, so the gauge is 1/8.
The higher the pitch, the more dense the carpet is, so would be applicable for commercial use.
The flame-spread rating of wood panel wainscoting must be:
A. Class B if the wainscoting takes up more than 10% of the wall area
B. Based on location and occupancy
C. A minimum of Class A
D.Nothing, because it is not regulated
B. Based on location and occupancy
Explanation: Wood wall finishes of paneling or wainscoting are regulated in the same way as other wall and ceiling finishes. The minimum flame-spread rating depends on the occupancy and the location in the building.
What considerations may influence the selection of FF&E?
A. Durability
B. Budget
C. Life Safety
D. All of the above
D. All of the above
Explanation: In making furnishing decisions, the designer should consider all of these items.
What performance tests should be specified for a custom-blended fabric to be used in a recreation center reception area?
A. Flammability and Fadeometer
B. Wyzenbeek and Fading
C. Indentation load deflection test
D. Taber and Wyzenbeek
B. Wyzenbeek and fading
Definitions:
Wyzenbeek abrasion resistance test: wearability measures the number of double rubs applied to a test sample before failure. Light-duty upholstery fabrics are a minimum 3000 double rubs. Medium-duty = 9000 double rubs. Contract use fabrics = 15000 double rubs. Commercial fabrics = 30000 double rubs.
Taber abraser test: most often used for testing carpet not fabric.
Flammability is rarely an issue because most contract or institutional fabrics are Class A, however designers must always check.
Cushioning also affects the comfort and washability of furniture. An indentation load deflection test is for cushioning, but the question asks about fabric only.
When using wood flooring, what would be done during installation to provide a more resilient floor that is more comfortable underfoot and allows for extra moisture to escape?
A. Use an underlayer of polyethylene film
B. Use a plywood or particleboard subfloor
C. Float floor instead of nailing or gluing to subfloor
D. Lay the floor on wood sleepers
D. Lay the floor on wood sleepers
Explanation: Wood flooring can be laid on sleepers. This method of installation not only gives a more resilient floor that is more comfortable underfoot, but it also provides an air space so any excess moisture can escape.
The interior designer’s best source concerning the limitations on the use of a product can be obtained from the:
A. manufacturer who makes the product
B. building code official who inspects the product
C. trade association representing the product type
D. specialty contractor who installs the product
A. manufacturer who makes the product
Explanation: All manufacturers know the limitations of their products and should be consulted when one of their products is going to be used in a specific special situation that the interior designer knows about.
Although the other sources may be consulted for additional information, only the manufacturer knows the limitations of a product.
What is luminous efficacy?
This is the ratio of the luminous flux emitted by a light source to the power used by the light source.
How does a fluorescent lamp produce light?
In this type of lamp, an electric arc is formed, generating ultraviolet light. When this light strikes the phosphor coating on the inside of the lamp, the phosphor fluoresces, generating visible light.
What is an LED?
This is a semiconductor device that uses solid state electronics to create light.
What is a color rendition index?
This is a numerical measure of how well a light source renders the color of an object when compared to the same object lit by a reference source of the same color temperature.
What is the coefficient of utilization?
This value is a measure of how efficiently a luminaire distributes light under various degrees of finish reflectivity.
How does a high intensity discharge lamp work?
This type of lamp works by passing an electric current through a gas or vapor under high pressure.
How is the color temperature of a light source determined?
This value is based on the temperature, in degrees Kelvin, to which a black body radiator would have to be heated to produce the same hue as a particular light source.
What is a lumen?
This unit is the amount of luminous flux produced by a point source of one candlepower in a solid angle of one steradian.
In terms of paint, what is the vehicle and how does it work?
This is the liquid portion of paint, composed of a nonvolatile binder and a volatile part called the solvent. The binder combines with the body to form the final film, while the solvent dissolves the binder to allow for application and later either evaporates or dries.
What is illuminance?
This is the density of luminous flux incident on a surface in lumens per unit area.
Your client wants a frame less glass door at all office fronts. They want the door hardware completely concealed and are concerned with the sound transmission from the corridor into the offices.
Which option would be the best solution to their requests?
A. provide a center-hung pivot with surface mounted closer
B. provide an offset pivot with surface mounted closer
C. provide a center-hung pivot door with concealed closer and optional pile seal
D. provide an offset pivot with concealed closer
C. provide a center-hung pivot door with concealed closer and optional pile seal
Explanation: Center hung pivots are totally concealed, while offset pivots are not, therefore center hung is the right choice if the desired look is totally concealed. The pile seal reduces sound transmission at the hinge and strikes the sides of the door.
What product information resource indexes products by MasterFormat number?
A. trade journals
B. manufacturer’s cut sheets
C. Sweets Directory
D. trade associations
C. Sweets Directory
Explanation: Many manufacturers of architectural, engineering, and interior design products also publish all, or a portion of, their product information in the Sweets Directory online.
