Hi Dan,
PFC-14 is already present as mole_fraction_of_carbon_tetrafluoride_in_air (
http://vocab.nerc.ac.uk/collection/P07/current/GYGQPPOA/).
Otherwise look fine.
Cheers, Roy.
I have now retired but will continue to be active through an Emeritus Fellowship using this e-mail address.

Subject: [CF-metadata] More trace gas standard names
Hi All,
I'd like to propose the following standard names for trace halogenated compounds measured on our Medusa GCMS instrument:
PFC-14
Standard name: mole_fraction_of_pfc14_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for pfc14 is CF4. The IUPAC name for pfc14 is tetrafluoromethane.
PFC-116
Standard name: mole_fraction_of_pfc116_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for pfc116 is C2F6. The IUPAC name for pfc116 is hexafluoroethane.
PFC-318
Standard name: mole_fraction_of_pfc318_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for pfc318 is c-C4F8. The IUPAC name for pfc318 is octafluorocyclobutane.
NF3
Standard name: mole_fraction_of_nitrogen_trifluoride_in_air (Canonical unit: 1)
Long name: 'Mole fraction is used in the construction mole_fraction_of_X_in_Y, where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". The chemical formula for nitrogen trifluoride is NF3. Nitrogen trifluoride is the IUPAC name.
HFC-227ea
Standard name: mole_fraction_of_hfc227ea_in_air (Canonical unit: 1)
