Metrology Course code: MET 331110 | 6 ECTS credits

Basic information
Level of Studies: Undergraduate applied studies
Year of Study: 2
Semester: 4
Requirements:
Goal: Introducing the students to the importance of measuring, statistical processing of the results and experimental testing in the textile industry.
Outcome: Upon finishing the course, the students should: know and use scientific terminology, understand terms related to measuring; posess the ability to apply statistic methods. They are able to choose an appropriate measuring process and keep up with contemporary testing methods in the textile industry.
