Which covers the popular manufacturing formula including 0.5% Cu.

I see that in that article

Tin pest in Sn-0.5 wt.% Cu lead-free solder

Sliver solder does not supress tinpest, very much reduces its growth, but
not supressed like leaded solder.

I wonder just what we have waiting in store for us.

I had considered applying to the Comission for exemption for all goods
regularly subjected to vibration (such as used on location video and sound
recording) and which also might be subjected to freezing temps in use or
transit which could at least exempt pro A/V gear.

It seems one (at least one) loudspeaker manufacturer successfully got an
exemption on these grounds.
