Ch.20 Selection of materials, finishes, and furnishings Flashcards
What does MSDS stand for
 material safety data sheets
What are the five groups of the criteria for the selection of materials and finishes
Function, durability, maintainability, safety/health, and cost
These qualities of a material relate to the materials ability to absorb sound or to block the transmission of sound. For most finished materials, sound absorption is the more important criteria and is typically measured in the noise reduction coefficient in our seat. For open plan office design, the articulation class of ceilings may also be important
Acoustic qualities
These criteria are commonly one of the first criteria considered by the designer. However, the appearance of the material must be balanced with all of the other technical and cost criteria. The basic elements and principles of design are related here
Aesthetics
This function of material relates to how easily a product can be obtained and if it can be delivered to the job site in a time to maintain the overall project schedule. Some specialty products can require six months or more to get. Other products are in stock for immediate delivery but may only be available in a limited choice of colors and finishes. Some products, such as furniture, are specifically available in quick ship programs to meet right schedules
Availability
This function of design is related to the color, texture, and other visual characteristics that will vary depending on what manufactures offer. So manufactures or product lines may have a wide range of choice than others, and the fact of anime sway the decision to use a particular company or material
Choice
This function of design is the precise sequence of steps needed to place material or product into the work. Installation methods can affect the cost in scheduling of the material and whether skilled workers will be required or not. In most cases, these for the same types of materials will be very similar. However, some specialty items may require a particular method using factory approved installers
Installation method
This relates to the service ability of the product or material when in use. There are many aspects of durability, and one or more of these may apply to a particular product
Durability
The ability of a material or finish to resist being worn away or to maintain its original appearance when rubbed with another object
Abrasion resistance
Is the method by which one material is connected to another. This criteria can’t have a significant influence on the product selection, depending on the substrate. Some products for materials cannot be attached to other materials we can only be attached with significant expense or effort.
Attachment
The capability of a material to resist adhesion or sticking between two surfaces of a wall covering
Blocking resistance
Refers to below that, when placed on a material, it’s just great enough to break the material.
Breaking strength
In materials resistance to damage, change of finish, or other deleterious changes resulting from exposure to chemicals
Chemical resistance
Refers to the ability of a thin coating, like wall covering her paint, to adhere to its substrate
Coating adhesion
The resistance of coded or decorated surfaces to cracking when they are exposed to low temperatures
Cold cracking resistant
The products resistance to deterioration by a chemical or electro chemical reaction resulting from exposure to moisture, chemicals, or other elements. This is typically a problem when metal products are supposed to moisture
Corrosion resistance
The resistance of a finish to change or loss of color when exposed to light, most commonly the ultraviolet light of the sun
Colorfastness
Materials resistance to the transfer of color from the wall covering surface when rubbed
CRocking resistance
The measure of how will a product is assembled in the factory. Each industry establishes measures of fabrication quality. For example, woodwork is measured according to three great economy, custom, and premium has established by the architectural woodwork Institute
Fabrication quality
The wall coverings resistance to deterioration caused by high temperatures over an extended time
Heat aging resistance
The ability of paint or other finishes to resist loss of color when exposed to sunlight. It is similar to colorfastness
Lightfastness
Materials ability to be cleaned repeatedly with a brush or detergent
Scrub ability
A decrease in dimension when a material is exposed to moisture. This characteristic is most typically applied to fabrics
Shrinkage
Materials resistance to a change in appearance after an application and removal of another material. As with chemical resistance, all products are resistant to some agents more than others, so manufactures literature should be consulted to verify the material is resistant to this agent likely to be present in a particular application
Stain resistant
