This is the only type of welding on the list which does not involve creating an electrical arc to weld. This process requires the use of two gases, acetylene and oxygen, to create a flame hot enough to melt steel. Apply this flame to the steel you are welding and it creates a lasting weld.
By eliminating use of both terms, the final intent of the IFT report will be realized by simply using the term Time/Temperature Control for Safety Food or TCS. Stakeholders that use the FDA Food Code will be able to communicate clearly with others and the public more effectively using this simple term. Emphasis on time and temperature in the name of this definition will focus attention on critical elements of food safety that can be effectively controlled.
The report advised that use of both terms (e.g. PHF/TCS) during a transition phase would facilitate migration from one term to the next. Now over a decade since the IFT report, the transition term has been in common use in the FDA Food Code since 2005. The definition of Potentially Hazardous Food (Time/Temperature Control for Safety Food), abbreviated PHF/TCS in the FDA Food Code, has now been in common use for over six years. While it has served its purpose for introducing the new term, the time has come to complete the migration to the new definition.
