Other relevant standards
Other relevant standards
There are a number of other standards which come into the picture during the course of this case.
The most important is not, strictly speaking, a sterility standard at all. It is EN 13795-1. That standard is entitled: “Surgical clothing and drapes – Requirements and test methods” and covers performance in matters such as resistance to penetration of liquids, the degree of mechanical stress on the materials and electrostatic performance.
Linked to this standard are standards such as EN 17141 relating to clean controlled environments in manufacturing areas where medical devices are produced.
Also occurring in the references within the material are:
EN ISO 13485 – “Quality systems — Medical devices — Particular requirements for the application of EN/ISO 9001” ([Model for quality assurance in design/development, production, installation and servicing]). These are the foundational standards on top of which ISO 11137 sits;
EN 550, 552 and 554 which deal with various other types of sterilisation procedures;
EN 1174 - sterilization of medical devices — Estimation of the population of micro-organisms on product.
