• There is no correlation in the pass/fail data
  among those labs that run according to the Rule
  or Handbook.
• All of the failures reported by all of the labs
  were due to weight loss. No failures were due to
  burn length.
• The majority of labs recorded greater horizontal
  bottom burn lengths than horizontal top burn
  lengths.
• The air velocity through the burner may be one of
  the reasons that cause the rapid breaching of the
  hook and loop closures and blocking layer into
  the polyurethane foam, resulting in failures of
  those test samples.
• The use of tabs and or a static disk may
  influence test results.
• The thermocouple type used for calibration
  purposes appears to be the wrong type for this
  test.
