ISO 1135-3:2016 specifies requirements for types of blood-taking sets for medical use in order to ensure functional interchangeability of transfusion equipment. It is applicable to sterilized blood-taking sets intended for single use only.
ISO 1135-3:2016 also aims to provide
a) specifications relating to the quality and performance of materials used in transfusion equipment, and
b) a unified presentation of terms for such equipment.
In some countries, the national pharmacopoeia or other national regulations are legally binding and take precedence over ISO 1135-3:2016.
