Flashcards in IDFX/IDPX 4 - FF&E, Interior Finishes, Materials, and Lighting Deck (31):
1

To specify an acceptable type of wallcovering, which test should the designer require that the wallcovering pass?

The Steiner tunnel test (ASTM E84) is used to measure the flammability of wall finishes and is the test most often required in building codes.

2

What most affects the flammability of upholstery?

Cushioning and surface fabric

Although chemical retardants and interliners are important considerations in upholstery flammability resistance, the combination of surface fabric and cushioning has the greatest effect.

3

When do warranties typically go into effect?

On the date of substantial completion

Substantial completion is the stage when the work is sufficiently complete in accordance with the contact documents so that the owner can occupy or utilize the work for its intended purpose.

The substantial date of completion is important because it has legal implications. For example, in many states the statue of limitations for errors possibly caused by the interior designer begins with the date of substantial completion. Warranties usually commence on the date of substantial completion.

4

What should be called out on cabinet drawings to ensure a good fit next to existing construction?

Scribe pieces at cabinet edges

A scribe piece allows for field cutting so the edge of a cabinet or countertop can be trimmed to fit the irregularities of the wall exactly.

5

What fabric would have the best appearance for the longest time when used in seating for a movie theater?

Wool/nylon blend

Theater seating requires a fabric that is resilient, durable, and flame retardant. The only combination that meets these requirements is the wool/nylon blend.

6

Which flooring test provides the best measure of slip resistance?

ASTM D2047

establishes criteria for static coefficient of friction (COF) measurements of flooring surfaces.

7

The risk for furniture being damaged during shipment is assigned by the:

Uniform Commercial Code

The Uniform Commercial Code (UCC) assigns risks by allowing the factory and vendor to use "F.O.B. factory" or "F.O.B. destination" to determine at what point title is transferred and who is at risk for shipping damage.

8

The flame-spread rating of wood panel wainscoting is based one what two factors?

Location and occupancy

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.

9

The interior designer is charged with tracking FF&E costs for a restaurant project.

The client is requesting different appliance specifications than originally priced for the contractor to purchase. How should the interior designer proceed?

The interior designer should compare the client’s specifications with the original allowance in the FF&E budget

10

During furniture installation, who is ultimately responsible for product assembly?

The vendor or seller of the goods

11

What is the industry standard abrasion resistance test for durability of woven textile fabrics?

Wyzenbeek abrasion resistance test

12

What is the typical term used to describe the furniture sales agreement between the client and interior designer?

Proposal

13

Test that measures the flammability of draperies, curtains and other window treatments.

Draperies that weigh less than 21 oz./yd. are tested separately from those that weigh more than 21 oz./yd. (ex. those with blackout linings). The test is pass/fail.

vertical ignition test (NFPA 701)

14

Tests the flame spread rating of Interior Finishes and Building Materials, specifically wall and ceiling finishes.

Building materials are rated from A – C, with A being most fire resistant. These ratings are used by building codes to specify the minimum rating for materials that can be used in a area by occupancy type.

Steiner Tunnel Test – also know as ASTM E84

15

This test measures a carpet’s ability to spread flame in a corridor or exit way when a fully developed fire is nearby. This test also measures the distance of any flame spread that occurs.

Flooring radiant panel test (ASTM E648)

16

This pass/fail test measures the flame resistance of textile floor coverings. It is required for all carpet sold in the United States.

ASTM D2859 methenamine pill test

Also called the Standard Method for Ignition Characteristics of Finished Textile Floor Covering Materials

17

How can composite wood veneers can be used?

As a green alternative to standard wood veneers

Composite wood veneer is an artificial product that uses readily available and fast growing renewable trees to make veneers that are stained and reformed into an artificial log that is then sliced to produce a new veneer. It is considered a sustainable or "green" product.

18

Which type of wood flooring could be installed easily and LEAST expensively in a residential living room?

Parquet

19

Which test determines the colorfastness under light exposure of textile materials?

AATCC 16

The AATCC 16 (American Association of Textile Chemists and Colorist) test uses a Fade-Ometer to determine the color fastness under light exposure of textile materials using six different test options. The most common test option uses xenon arc lamp with continuous light.

Although many tests evaluate aspects of colorfastness, panel and upholstery fabrics are most commonly tested for Colorfastness to Light (AATCC 16) and Colorfastness to Crocking or rubbing (AATCC 8).

20

Which type of veneer match would give your client the desired starburst effect for their reception area?

Reverse diamond match

A diamond pattern would create a diamond effect. When reversed, it would create a sunburst or starburst like pattern.

21

Which flooring test provides the best measure of slip resistance?

ASTM D2047

Of the test methods given, all have been withdrawn except ASTM Test Method D2047, which establishes criteria for static coefficient of friction (COF) measurements of flooring surfaces. However, this test is only designed for testing dry surfaces.

ASTM C1028 can be used on wet or rough surfaces, but can only be used as a relative comparison between 2 similar surfaces.

22

Which of the following is NOT a consideration in determining the flammability of a fabric?

1. smoke developed

2. increases flame spread

3. Steiner Tunnel test

4. emissions that result when chemicals that contain carbon and hydrogen vaporize at temperature

Emissions that result when chemicals that contain carbon and hydrogen vaporize at temperature

Flammability is the likelihood that a material will combust. For most materials flammability is rated in terms of flame spread, smoke developed, and fuel contributed.

The most common test developed for flame spread and smoke is the Steiner tunnel test, ASTM E84.

23

An interior designer has been retained for a building project that is currently being planned by an architect. On the second floor of the building, slate flooring over a concrete subfloor is being used. What type of installation should ideally be designed for?

Thick-set application using a cleavage membrane

Because slate does not have a uniform thickness and a concrete subfloor above grade may deflect and cause cracking, the best installation is a thick-set method with a cleavage membrane.

The thick-set method allows the tile setter to adjust the bed according to the exact thickness of each stone, and a cleavage membrane (with reinforcement) allows the finish floor to float above any slight deflection of the concrete floor.

24

Which of the following fabrics would be a poor choice to use for upholstery in a hotel atrium?

1. cotton

2. rayon

3. wool

4. nylon

Rayon

Rayon is a regenerated cellulosic fiber. It has very poor resistance to sunlight and poor resiliency. It has high absorbency, low resistance to water and moisture and is flammable. It is seldom used for upholstery.

25

What is the difference between curtains and drapery?

By definition, curtains are generally not intended to be opened, as opposed to drapery, which open and close.

26

If a material supplier says that adding his product to a wall assembly in a critical acoustic situation would increase the noise reduction (STC rating) between two rooms by slightly more than 3 dB, what should the designer’s reaction be?

Thank him for stopping by, but explain that the amount of noise reduction is nominal

Because a change in intensity level of 3 dB is considered just perceptible, it would probably be better not to use the material, regardless of how low the added cost was.

Trying to modify the material to 6 dB would also probably not be worth the trouble. If an STC rating of 6 dB or higher is needed, it would be better to look at another construction assembly instead of trying to make do with a modified material.

27

What is the characteristic of a Class I fire-rated carpet?

It does not ignite

The Flooring Radiant Panel Test (ASTM E 648, NFPA 253) measures the lowest level of radiant energy necessary for a fire to continue to burn. The distance a carpet test specimen burns to extinguishment is measured and converted into watts per square centimeter (i.e. the heat energy radiated onto the surface of a material), which is referred to as critical radiant flux.

The higher the critical radiant flux number yielded by a carpet in this test, the more resistant it is to spreading flame.
Based on this test, flammability ratings of carpet are reported as either Class I (a minimum of 0.45 watts/sq cm), or Class II (a minimum of 0.22 watts/sq cm). Typically, a carpet with a Class I Radiant Panel rating is required in corridors, entrances and exits of commercial facilities, and a Class II Radiant Panel rating is required for all other areas.

28

What should a designer do to create the most concise specifications with the least amount of text?

Use a reference standard specification

A reference standard specification is a variation of the descriptive specification type that describes a material, product, or process based on requirements (reference standards) set by an accepted authority or test method.

These documents describe in great detail the requirements for products and requirements do not need to be repeated. Reference specifications are fairly easy to write and are generally short. Chances for errors are reduced and liability is minimized because industry standards and generally recognized methods of building are being used.

29

Solid stock lumber is cut from a log in all of the following ways EXCEPT?

1. rift sawing

2. quarter sawing

3. plain sawing

4. rotary sawing

Rotary sawing

The way lumber is cut from a log determines its final appearance of the grain pattern. There are three ways solid stock is cut from a log: plain sawing (also called flat sawing), quarter sawing and rift sawing.

30

When selecting interior partition finishes to meet flame-spread standards, what are the most important considerations?

The occupancy group, and the location in the building where the finishes will be used

Building codes limit flammability of finishes based on the occupancy of the building and whether the finishes are in an exit or not. A sprinkler system may allow a reduction in one flame-spread class rating but it is not the overriding variable. Flame-spread requirements are also independent of the rating of the assembly on which the finishes are placed.

31

After defining the exact scope of work and selecting individual floor finish types for each area of your project, you must provide your client with an updated working budget number.
Which method of estimating would be used at this time?

1. Square Footage Method

2. Local Cost Indicies

3. Parameter Method

4. Matrix Costing

Parameter method

At this time in a project, floor finishes can be broken down into individual types (carpeting, vinyl tile, wood-strip flooring) and multiplied by an estimated cost per square foot; however since specific products have not been selected, this estimate typically uses base unit pricing per material type.

The square footage method is based off of project size and is used before much design work has started.

If the project has progressed to the point of specific manufacturers and products, then the designer can use the detailed quantity takeoff method for a fairly exact budget.

Matrix costing deals with pricing alternatives.
