66. Frage
What is it called when moisture causes wood flooring to expand, resulting in the edges being higher than the center across the width of the board?
Antwort: B
Begründung:
Cuppingis the correct term used in the IICRC WRT body of knowledge to describe a condition where wood flooring expands due to moisture, causing the edges of each board to rise higher than the center. This deformation occurs because moisture is absorbed unevenly-typically from below-causing differential expansion across the board's thickness.
The WRT manual explains that cupping is most commonly associated with moisture intrusion affecting subflooring or elevated humidity conditions beneath the flooring. As the underside of the board absorbs moisture, it expands more than the top surface, resulting in a concave shape across the width.
This condition is distinct fromcrowning, which is the opposite deformation where the center is higher than the edges, often occurring after sanding cupped floors before moisture equilibrium is restored.Bucklingrefers to extreme deformation where boards lift completely from the subfloor, anddelaminationapplies to layered materials separating.
Understanding cupping is essential for restorers because it influences drying strategy, expectations, and post- drying recommendations. The WRT standard emphasizes careful moisture control and adequate acclimation time to allow wood flooring to return as close as possible to its original profile before repairs or refinishing are attempted.
67. Frage
If indoor conditions are 90°F (32°C) and 60% relative humidity, at what surface temperature does condensation begin to occur?
Antwort: A
Begründung:
Condensation occurs when a surface temperature reaches or drops below thedew point temperatureof the surrounding air. The IICRC WRT body of knowledge emphasizes that dew point-not relative humidity alone-determines when condensation will form.
At90°F and 60% RH, the corresponding dew point is approximately74°F. Any surface at or below this temperature will experience condensation as water vapor changes phase from gas to liquid.
This principle is critical in restoration drying because unintended condensation can re-wet materials and cause secondary damage. The WRT curriculum trains restorers to monitor both air dew point and material surface temperatures to prevent this condition.
Lower temperature options listed would represent colder surfaces but condensation would already occur once the surface reaches the dew point. Therefore, 74°F is the correct threshold.
68. Frage
Which term is defined as the process of water changing from a liquid to a gas?
Antwort: C
Begründung:
The IICRC WRT body of knowledge definesevaporationas the process by which water changes from a liquid state to a gaseous (vapor) state. This process is central to restorative drying because it is how moisture leaves wet materials.
The WRT manual explains that evaporation occurs at the surface of materials and is influenced by airflow, surface temperature, humidity, and vapor pressure differential. Evaporation alone does not remove moisture from the structure; it must be paired with dehumidification or ventilation to remove the vapor from the air.
Hydrostatic refers to water pressure, sublimation is the change from solid to gas, and dehumidification removes vapor from air-not liquid from materials. Understanding evaporation allows restorers to design drying systems that maximize moisture release while preventing condensation and secondary damage.
69. Frage
As the humidity ratio and dew point increase or decrease, what other psychrometric measurement also increases or decreases proportionally?
Antwort: B
Begründung:
The IICRC WRT body of knowledge explains thathumidity ratio, dew point, and vapor pressure are directly related psychrometric measurements. When humidity ratio increases or decreases, both dew point and vapor pressure change proportionally.
Vapor pressure represents the energy exerted by water vapor molecules in the air. As more moisture is added to the air (higher humidity ratio), vapor pressure increases; when moisture is removed, vapor pressure decreases. Dew point follows the same pattern because it reflects the temperature at which that vapor pressure results in saturation.
Temperature and permeability are not directly proportional to humidity ratio, and dehumidification rate is a performance outcome rather than a psychrometric property.
Because vapor pressure governs moisture movement between materials and air, its proportional relationship to humidity ratio and dew point makes it one of the most important measurements in WRT drying science.
70. Frage
Which device is used to measure the temperature and relative humidity of the air?
Antwort: D
Begründung:
Athermo-hygrometeris the instrument identified in the IICRC WRT body of knowledge for measuring both air temperature and relative humidity. These two measurements are fundamental inputs for psychrometric evaluation and drying documentation.
The WRT curriculum explains that accurate air readings allow restorers to calculate additional psychrometric values such as humidity ratio, dew point, and vapor pressure-either manually or using built-in instrument calculations. These values are critical for assessing drying conditions, equipment performance, and the effectiveness of the drying strategy.
Moisture meters and moisture sensors are used to measure moisture in materials, not air. A thermometer measures temperature only and cannot determine moisture content or humidity conditions. The thermo- hygrometer integrates both functions into a single instrument, making it a required tool for daily monitoring under the WRT standard of care.
The WRT manual further stresses consistency in air measurements, recommending similar measurement locations and procedures during each monitoring visit to ensure defensible documentation.
