Direct answer
Self-closing is a defined term in the International Building Code (IBC) 2009, in Fire and Smoke Protection Features. The code's own words are: “As applied to a fire door or other opening protective, means equipped with an device that will ensure closing after having been opened.” The IFC 2009 defines the same term with different wording, so the controlling text depends on which code governs the question in front of you — the comparison below sets the versions side by side. The term is used in 30 chapters of this corpus, most often in Flammable and Combustible Liquids (IFC 2009), Special Detailed Requirements Based on Use and Occupancy (IBC 2009), Fire and Smoke Protection Features (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

The term in use
How the code actually writes about self-closing, quoted from the 2009 text hosted here:
Doors shall be well fitted, self-closing and equipped with a three-point latch.
Corridor doors, other than those in a wall required to be rated by Section 508.2.5 or for the enclosure of a vertical opening or an exit, shall not have a required fire protection rating and shall not be required to be equipped with self-closing or automatic-closing devices, but shall provide an effective barrier to limit the transfer of smoke and …
Automatic-closing fire door assemblies shall be self-closing in accordance with NFPA 80.

The definition above leans on 2 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what self-closing covers:
- Approved — IBC 2009: Acceptable to the code official or authority having jurisdiction.
- Device — IRC 2009: Aunit of an electrical system that carries or controls electrical energy as it principal function.

Frequently asked questions
What is the code definition of self-closing?
The International Building Code (IBC) 2009 defines it in Fire and Smoke Protection Features as: “As applied to a fire door or other opening protective, means equipped with an device that will ensure closing after having been opened.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.
Which parts of the code depend on self-closing?
In this corpus the term is used across 30 chapters, led by Flammable and Combustible Liquids in the IFC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.
What is considered a self-closing door?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Fire and Smoke Protection Features: “As applied to a fire door or other opening protective, means equipped with an device that will ensure closing after having been opened.” It is defined in IBC 2009, IFC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
What is a self-closing faucet?
In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Fire and Smoke Protection Features: “As applied to a fire door or other opening protective, means equipped with an device that will ensure closing after having been opened.” It is defined in IBC 2009, IFC 2009. It is not the same as Faucet, which the IPC 2009 defines separately as “A valve end of a water pipe through which water is drawn from or held within the pipe.” Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
