What is the difference between Raymond and ISO Die Springs and what are their colour codes?

• Both types of indicated die springs are produced by Associated Spring Raymond with the highest quality standard
• The ISO springs with the designation 0R... were defined subsequently by the ISO standardization organization and are intended for use with stamping and forming dies
• Many dimensions of the two series of springs are absolutely identical in terms of external measurements; however, the series have different color coding systems
• It should be kept in mind that the ISO has set such large tolerances that e.g. the rounding of the edges and the profile cross-sections can exhibit great variation with the resulting solid lengths
• Our products traditionally have a demonstrably long service life, which is due to very good quality.
