CPSI ASTM and CPSC Standards Questions and Answers 3 — Questions and Answers
Question 1: According to ASTM F1292, what property does the standard measure to assess the impact attenuation of playground surfacing materials?
- Coefficient of friction
- HIC (Head Injury Criterion) (Correct answer)
- Compressive strength
- Tensile modulus
Correct answer: HIC (Head Injury Criterion)
ASTM F1292 measures the Head Injury Criterion (HIC) value to evaluate whether a surfacing material adequately attenuates impact forces.
Question 2: The CPSC Handbook for Public Playground Safety recommends that the use zone for a single-axis swing extend in front of and behind the seat by at least how many times the height of the pivot point?
- 1 times
- 2 times (Correct answer)
- 1.5 times
- 2.5 times
Correct answer: 2 times
The CPSC Handbook specifies that the use zone for swings must extend at least twice the height of the pivot point in front of and behind the seat.
Question 3: Under ASTM F1487, which of the following is considered an 'entrapment' hazard on playground equipment?
- An opening between 3.5 and 9 inches (Correct answer)
- A protrusion longer than 0.5 inches
- A handrail diameter over 1.9 inches
- A slide gradient steeper than 50°
Correct answer: An opening between 3.5 and 9 inches
ASTM F1487 identifies openings between 3.5 and 9 inches as head entrapment hazards because a child's body may pass through while the head cannot.
Question 4: ASTM F1292 requires that loose-fill surfacing materials be tested at what two conditions to establish certified fall height performance?
- Wet and dry
- New and aged/compacted (Correct answer)
- Frozen and thawed
- Indoor and outdoor
Correct answer: New and aged/compacted
ASTM F1292 requires testing surfacing both in new/uncompacted and aged/compacted states because compaction significantly reduces impact attenuation.
Question 5: According to CPSC guidelines, what is the minimum depth of loose-fill wood chips or bark required to provide adequate protection for a fall from a height of 7 feet?
- 6 inches
- 9 inches
- 12 inches (Correct answer)
- 15 inches
Correct answer: 12 inches
CPSC guidelines recommend at least 12 inches of loose-fill wood chips or bark to adequately attenuate impact from a 7-foot fall height.
Question 6: Which ASTM standard specifically addresses the safety performance specifications for impact-attenuating surfacing used beneath playground equipment?
- ASTM F1148
- ASTM F1292 (Correct answer)
- ASTM F1487
- ASTM F2075
Correct answer: ASTM F1292
ASTM F1292 is the standard that establishes impact attenuation performance requirements for playground surfacing materials.
Question 7: Under ASTM F1487, what is the maximum permissible angle from vertical for a protrusion on playground equipment before it constitutes an impalement hazard?
- 30 degrees
- 45 degrees (Correct answer)
- 60 degrees
- 90 degrees
Correct answer: 45 degrees
ASTM F1487 considers protrusions that angle 45 degrees or more from vertical, combined with sufficient projection, as potential impalement hazards.
