Certification marks

Keyboards and other products can be certified with a surprisingly large number of standards and testing agencies around the world. Certification marks found on input devices are listed below. This list is not exhaustive.

The images are presented in the monochrome ink or injection-moulded solid fill form in which they appear on keyboards.

Marks	Agency/Standard	Country	Notes
	ACMA Regulatory Compliance Mark	Australia
	Bureau of Standards, Metrology and Inspection (BSMI)	Taiwan
	Canadian Standards Association	Canada, USA
	C-Tick	Australia
	CE marking (unofficially "Conformité Européenne")	EU
	台灣交通部電信總局DGT認證	Taiwan	Translates to something like "Taiwan Ministry of Communications General Directorate of Telecommunications (DGT) certification" — this may be an obsolete certification, but it was found alongside the BSMI mark (also Taiwan) on a 2003 Logitech Cordless Keyboard (Y-RJ20)
	EurAsian Conformity Mark	Eurasian Customs Union	Replaces the GOST R mark below
	Environment Friendly Use Period of 10 years (China RoHS)	China	The Environment Friendly Use Period (EFUP) is the period of time in years before any restricted substances are likely to leak out; possible periods include 5, 7, 10, 25 and 50 years, with 10 being the period typically found on electrical goods. A circled letter "e" indicates that the product contains less than the maximum concentration value of all six of China's restricted hazardous substances.
	FCC Declaration of Conformity	USA	Old mark
	FCC Declaration of Conformity	USA	New mark
	GS mark (geprüfte Sicherheit)	Germany	Geprüfte Sicherheit certification will be carried out by an organisation such as TÜV Rheinland, TÜV SÜD or (particularly with Cherry) VDE, and the relevant organisation logo will typically appear to its left
	GOST R	Russia	Largely obsolete; replaced with the EurAsian Conformity Mark above
	Korea Communications Commission	South Korea
	Korea Certification	South Korea	With Dell keyboards, the manufacturer details are sometimes recorded on the rear label or box.
	Ministry of Information and Communication	South Korea	Defunct; replaced with the Korea Communications Commission
	Norma Oficial Mexicana	Mexico	Mexican official standards
	NYCE (Normalización y Certificación NYCE, S.C.)	Mexico	Generally accompanies the Mexican NOM mark
	Serbian Conformity Mark	Serbia	Apparently equivalent to the CE mark
	TÜV Mark, TÜV Rheinland	Germany	The design varies greatly, and occasionally the name of TÜV Rheinland is omitted, leaving only the triangle. With keyboards, this is typically used to indicate the organisation responsible for GS certification.
	TÜV SÜD mark	Germany	The design varies; officially the image is in full colour and annotated, but the example at left is how it appears in single-ink printing on a Dell L100 keyboard.
	UkrSEPRO	Ukraine
	UL	USA, Canada	This may be accompanied by a UL File Number identifying the manufacturer.
	UL Recognized Component	USA, Canada	This may be accompanied by a UL File Number identifying the manufacturer.

	VDE Mark	Germany?	Not clear what their jurisdiction is, but the organisation is German
