TCO recently revised their requirements for the TCO 03 certification. An earlier requirement specified that the frame should not be too dark or too light was removed in October 2005. All other strictly specified requirements are kept intact.
TCO'03 is the fourth certification standard from TCO Development of Sweden. TCO are the initials (in Swedish) for the Swedish Confederation of Professional Employees. TCO'03 covers the same areas as the previous TCO'99 standard, but stricter regarding ecological and ergonomics requirements.
