## Key facts

| Fact | Value |
| --- | --- |
| Defined in | IMC 2009 (2009 editions transcribed in this corpus) |
| Primary source | IMC 2009 Definitions (model text, not a jurisdiction's adopted text) |
| Chapters using the term | 3 (counted across the codes hosted here) |
| Wording identical across codes | Single code (compare before citing one code's wording under another) |

## Direct answer

Reclaimed refrigerants is a defined term in the International Mechanical Code (IMC) 2009, in Definitions. The code's own words are: “Refrigerants reprocessed to the same specifications as for new refrigerants by means including distillation. Such refrigerants have been chemically analyzed to verify that the specifications have been met. Reclaiming usually implies the use of processes or procedures that are available only at a reprocessing or manufacturing facility.” No other I-Code in this corpus defines it, so the IMC 2009 definition is the one to work from. The term is used in 3 chapters of this corpus, most often in Refrigeration (IMC 2009), Building Services and Systems (IFC 2009), Definitions (IMC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

## The terms reclaimed refrigerants is built out of

The definition above leans on 1 other defined term. Each carries its own code definition, and a local amendment to any of them changes what reclaimed refrigerants covers:

- **[Facility](https://harth.build/resources/glossary/facility.md)** — IBC 2009: All or any portion of buildings, structures, site improvements, elements and pedestrian or vehicular routes located on a site.

Every row is a document this term depends on. The [ICC code library](https://codes.iccsafe.org/codes) and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) cover the middle rows.

## Frequently asked questions

### What is the code definition of reclaimed refrigerants?

The International Mechanical Code (IMC) 2009 defines it in Definitions as: “Refrigerants reprocessed to the same specifications as for new refrigerants by means including distillation. Such refrigerants have been chemically analyzed to verify that the specifications have been met. Reclaiming usually implies the use of processes or procedures that are available only at a reprocessing or manufacturing facility.” 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 reclaimed refrigerants?

In this corpus the term is used across 3 chapters, led by Refrigeration in the IMC 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.
