Daily Quiz (32)


The diffusion of colored matter from a substrate through a paint film causing discoloration is called what?


True or false: Though the standard ASTM F2170 requires 72 hours to achieve results, one-day results of relative humidity testing of concrete floors with in-situ probes is typically accurate enough to judge if it is acceptable to apply materials that can tolerate higher moisture content.


True or false: Polyurea coatings require use of low-voltage holiday detectors for continuity testing.


What is another name for a dolly used in coating testing?


True or false: ASTM offers only a visual method for determining the surface profile of concrete.


What inspection instrument uses a wet bulb and a dry bulb?


True or false: For non-conductive coatings up to 20 mils thick applied to conductive substrates, a low-voltage holiday detector is normally used to detect pinholes and other discontinuities.


What is the acronym for an instrument used to conduct the ASTM 4541 test, Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers?


What type of gages are used to measure the dry film thickness of coatings on concrete?


True or false: ASTM D4417 describes three methods for measuring surface profile of blast-cleaned steel using either a digital profile gage or a surface profile comparator or a portable stylus instrument.


True or False: ASTM D3359, “Standard Test Method for Measuring Adhesion by Tape Test,” measures the tensile adhesion of a coating.


How is profile measured in ASTM D4417?


True or false: The Performance Standard for Protective Coatings (PSPC) was created by ISO.


True or false: Prior to being used for measurements, all thermometers should be exposed to the environment they will be used in for sufficient time to allow them to stabilize, according to a recent JPCL article.


True or false: According to a JPCL article, one year is a good starting interval between calibrations of a magnetic dry film thickness gage.


One mil of coating thickness equals approximately how many microns?


A test that requires rubbing a clean black fabric across a painted surface evaluates what attribute of the paint?


What organization developed a standard for measuring concrete surface profile with replica putty?


True or false: There is no quantifiable test method for determining the surface profile on concrete substrates.


True or false: A Tooke gauge can sometimes be used to measure the thickness of individual coats of paint within a multicoat system.


True or false: ASTM has one pull-off adhesion test of coatings on concrete, and a separate one for coatings on metal substrates.


What is another name for a tensile adhesion test of coatings?


Continuity testing of non-conductive coatings applied to a steel substrate is carried out with what type of instrument?


True or False: The more turbid a liquid, the more clear it is.


True or False: ASTM D3359, “Standard Test Method for Measuring Adhesion by Tape Test,” measures the tensile adhesion of a coating.


What organization developed a standard practice for building enclosure commissioning?


Plastic shims are used with what quality-control instruments in coating work?


True or false: The Sealant Waterproofing and Restoration Institute (SWRI) has a Wall Coating Validation Program “to provide specifiers and end-users of wall coating products an unbiased method to judge whether wall coating products will perform at the levels of the manufacturer’s published data sheet for that particular product.”


When production is stopped for inspection of coating work prior to moving on to the next step, what is this quality control step called?


In which one of the following QC applications is a holiday detector (high or low voltage) normally not used?


Which of the following coating adhesion tests is the least quantitative?


What instrument is used for non-destructive measurement of the dry film thickness of coatings on concrete?
