Practice question

What is the structural difference between a standard trailer body certified to EN 12642 Code L and a reinforced trailer body certified to EN 12642 Code XL?

  1. Code XL bodies are reinforced and certified to absorb cargo forces through their walls (front wall 50% payload, rear wall 30%, side walls 40% when loaded form-fit without gaps >3cm), whereas Code L bodies have significantly lower wall strengths and require auxiliary cargo securing
  2. Code L bodies are for heavy transport (>40t) while Code XL bodies are for light commercial vans (<3.5t)
  3. Code XL requires all cargo to be secured with chains only
  4. There is no strength difference; Code XL only indicates extra internal loading height

Answer: A — Code XL bodies are reinforced and certified to absorb cargo forces through their walls (front wall 50% payload, rear wall 30%, side walls 40% when loaded form-fit without gaps >3cm), whereas Code L bodies have significantly lower wall strengths and require auxiliary cargo securing
