Unfortunately, there is no industry standard for 12” record weight. They can range from 80-200g.
What? What makes you say that? Just because you can buy records weighing in from 80 to 200g doesn’t mean that it’s a standard. I have played a custom made record weghing more than 1Kg for a customer once. The RIAA standards are fairly clear. And you’ll be surprised how much is non-standard. Martin
Strictly speaking Mark-sf is correct. The RIAA standard for records give dimensions, not weight. However, if you look at the standard, it requires 301.6mm diameter and 1.9mm (+- 0.3mm) thickness. This gives a volume of about 134cc, and hence a standard weight of about 185 gr (standard PVC @ 1.4 g/cc), or a range of about 160 – 210g if you take into account the thickness variation. So all those old 120g records are the ones which are non-standard, not the 180g ones.
