Please note that the translations of these standards (from the Spanish originals) have been edited to eliminate repetitions, to make them more readable and more uniform. Thus, the section numbers may not correspond to those in the original standards. In a few standards, the units vary from the "mg per 100 ml" generally used in most Ecuadorian Standards. These units have been changed for uniformity.
The parts per million ("p.p.m") figures do not appear in the original standards, but have been added for ease of comparison with standards from other countries. Whilst every effort has been made to translate the standards accurately, and in full, reference should be made to the original standards for authenticity.
