Answer :
Final answer:
The correct specification for engineered wood fiber as a playground safety surface is ASTM F2075, which ensures material safety and performance standards are met. Therefore the correct answer is: a)
Explanation:
The ASTM (American Society for Testing and Materials) develops and publishes technical standards for a wide range of materials, products, systems, and services, including those used in playground surfaces. While ASTM F1292 focuses on the critical fall height and performance of playground surfacing materials, ASTM F3351 involves the determination of accessibility of surface systems under and around playground equipment.
However, for specifically engineered wood fiber meant for playground safety surfaces, ASTM F2075 is the designated standard, ensuring the material meets certain criteria for particle size, purity, and ability to provide a safe playing environment.
