Kata Pengantar
ISO (Organisasi Internasional untuk Standardisasi) adalah aliansi global badan standar nasional (badan anggota ISO). Pengembangan standar internasional biasanya dilakukan melalui komite teknis ISO. Setiap lembaga anggota yang berminat pada suatu mata pelajaran yang telah dibentuk panitia teknisnya berhak untuk diwakili dalam panitia tersebut. Organisasi internasional pemerintah dan non-pemerintah yang berhubungan dengan organisasi standardisasi juga terlibat dalam pekerjaan ini.

Draft international standards adopted by technical committees are circulated to member bodies for approval before they are accepted as international standards by the ISO Council. They are approved according to ISO procedures that require at least 75% approval by voting member institutions.

The international standard ISO7252 was developed by Technical committee ISO/TC 35, Paints and varnishments.
