    Urea-formaldehyde resins may be safely used as the food-contact 
surface of molded articles intended for use in contact with food, in 
accordance with the following prescribed conditions:
    (a) For the purpose of this section, urea-formaldehyde resins are 
those produced when 1 mole of urea is made to react with not more than 2 
moles of formaldehyde in water solution.

conditions of time and temperature characterizing the conditions of its 
intended use as determined from tables 1 and 2 of Sec.  175.300(d) of 
this chapter, yields total extractives in each extracting solvent not to 
exceed 0.5 milligram per square inch of food-contact surface as 
determined by the methods described in Sec.  175.300(e) of this chapter.
    Note: In testing the finished food-contact article, use a separate 
test sample for each required extracting solvent.
