# §1610.8. Reporting results.

- (a) The reported result shall be the classification before or after refurbishing, whichever is the more severe; and based on this result, the textile shall be placed in the proper final classification as described in [§ 1610.4](/cfr/16/1610.4.md).
- (b) **Test result codes.** The following are definitions for the test result codes, which shall be used for recording flammability results for each specimen that is burned.
  - (1) **For Plain Surface Textile Fabrics—**
    - (i) **DNI Did not ignite.**
    - (ii) **IBE Ignited, but extinguished.**
    - (iii) _._sec. Actual burn time measured and recorded by the timing device.
  - (2) **For Raised Surface Textile Fabrics—**
    - (i) _._SFBB Time in seconds, surface flash base burn starting at places other than the point of impingement as a result of surface flash.
    - (ii) _._SFBB poi Time in seconds, surface flash base burn starting at the point of impingement.
    - (iii) _._SFBB poi* Time in seconds, surface flash base burn possibly starting at the point of impingement. The asterisk is accompanied by the following statement: “Unable to make absolute determination as to source of base burns.” This statement is added to the result of any specimen if there is a question as to origin of the base burn.
    - (iv) _._SF only Time in seconds, surface flash only. No damage to the base fabric.
    - (v) SF poi Surface flash, at the point of impingement only (equivalent to “did not ignite” for plain surfaces).
    - (vi) **SF uc Surface flash, under the stop thread, but does not break the stop thread.**
    - (vii) **SF pw Surface flash, part way.** No time shown because the surface flash did not reach the stop thread.
