Hi
a question to professional pcb designers in this forum:
What is the standard for the reference name of electronic components in circuit and pcb designs? (R1 = Resistor, D1 = Diode, K1 = Relais ...)
I was pointed to DIN EN 81346-2 that replaced the old DIN 40719-2.
Example: The new standard says a Diode is now "R" and not "D". 
Any thoughts about this? Do you follow this new standard?
Thank you!

The list below is the most commonly used 'industry standard':
R=resistor
D=diode (sometimes zeners have a Z)
C=capacitor
L=inductor
Q or T=transistor
TR=transformer
IC=chip
REL or K=relay
J=jumper/header
P or CON=connector
F=fuse
TP=test point
