===Aroclor mixtures ===
The only North American producer, [[Monsanto Company]], marketed PCBs under the trade name '''Aroclor''' from 1930 to 1977. These were sold under trade names followed by a four-digit number. In general, the first two digits refer to the product series as designated by Monsanto (e.g. 1200 or 1100 series); the second two numbers indicate the percentage of chlorine by mass in the mixture. Thus, Aroclor 1260 is a 1200 series product and contains 60% chlorine by mass. It is a myth that the first two digits referred to the number of carbon atoms; the number of carbon atoms do not change in PCBs. The 1100 series was a crude PCB material which was distilled to create the 1200 series PCB product.<ref>{{cite journal | vauthors = Erickson MD, Kaley RG | title = Applications of polychlorinated biphenyls | journal = Environmental Science and Pollution Research International | volume = 18 | issue = 2 | pages = 135–151 | date = February 2011 | pmid = 20848233 | doi = 10.1007/s11356-010-0392-1 | bibcode = 2011ESPR...18..135E | s2cid = 25260209 }}</ref>

The exception to the naming system is Aroclor 1016 which was produced by distilling 1242 to remove the highly chlorinated congeners to make a more biodegradable product. "1016" was given to this product during Monsanto's research stage for tracking purposes but the name stuck after it was commercialized.

Different Aroclors were used at different times and for different applications. In electrical equipment manufacturing in the US, Aroclor 1260 and Aroclor 1254 were the main mixtures used before 1950; Aroclor 1242 was the main mixture used in the 1950s and 1960s until it was phased out in 1971 and replaced by Aroclor 1016.<ref name="unep"/>{{page needed|date=October 2015}}
