History and explanation of the SMS 1586 standard

What SMS 1586 is

SMS (Sveriges Mekanstandardisering) size lists keep Nordic equipment and spare-parts catalogs consistent. You will see SMS callouts even when the same millimeter size also exists in ISO or DIN tables.

Why a dedicated chart helps

Nordic manuals and distributor books often say SMS explicitly. Matching that name on a handbook page is faster than hunting a generic metric list - and it avoids mixing up a “close” JIS or AS568 size.

Using this chart

Measure or read ID × CS in mm, open the CS group, confirm the row, then pick compound for the fluid and temperature.
