Objectives

The main objective of this unit is to provide to the students the necessary knowledge in order to comply with the accreditation requirements and to manage an accreditation process in chemical testing laboratories according to NP EN ISO/IEC 17025

Learning outcomes and competences

It is intended that at the end of this course, students show skills that enable them to:

1 Understand the fundamental concepts of quality assurance and quality control of a chemical laboratory;
2 Organize and design a quality assurance program in conformity with a reference to international standard NP EN ISO/IEC 17025;
3 Organize the documentation for accreditation of chemical Laboratories.

Teaching methods and learning activities

The lectures are detailed exposition of the content of the program, illustrated by study cases. The audio-visual aids are used to support the presentations. Guest lectures are given by laboratory managers on how to run an analytical laboratory. It is foreseen a set of planned visits to accredited laboratories.

Eligibility for exams

In this course it is mandatory to comply with the attendance in classes.

The students must attend a minimum of 75% of the total number of classes and to obtain a positive mark in written works done during the semester.

Students with the status of student work are not covered by the fulfillment of the previous condition.

Calculation formula of final grade

Final exam – individual evaluation - 35%: lowest mark 8.0/20 (round off to decimals)

Written Works performed in the context of classes: 25%: oral presentations, problems resolutions, homeworks. Lowest mark 9.5/20 (round off to decimals).

Two quizzes: 40%: lowest mark 8.0/20 (round off to decimals

Final evaluation: 25% Exam + 35% written works + 40 average of two quizzes

Students with the status of student work may be assessed by a final written test.

For the students with final mark greater than 17, there will be an extra oral exam in order to confirm, or not, the final mark.

Examinations or Special Assignments

Are not provided

Internship work/project

Not applicable

Special assessment (TE, DA, ...)

The special assessment shall be a written examination

Classification improvement

Distributed evaluation can not be improved.

The final mark can be improved only by final exam.
