For the course RENG 1005 Engineering Materials there are two practicals:
Practical Number Practical Room
Practical 1 Effect of Cold Working on Mechanical Properties M1-15
Practical 2 Comparison of Tensile Properties M1-09
Read through each practical before your session to determine where it is held and any preparation required and any particular safety precautions.
Practicals are designed to allow students to experience the variation of properties in materials and the effect of design and processing on properties and hence performance in service.
All practicals will be assessed for each student. Attendance records for all sessions will be maintained by staff and considered in the assessment of progress in the practical sessions. It is emphasised that attendance at ALL practicals sessions is compulsory. The “report” in this practical book should be completed within two weeks of the actual practical session. References in practical reports must follow a standard format such as:
Askeland, D.R. and Phule, P. R., “The Science and Engineering of Materials”, Fifth Edition, 2006, Thomson.
Instructions regarding writing a practical report can be found on the university webpage
http://www.unisa.edu.au/ltu/students/study/assessment/practical.asp or in University library.
2. GENERAL INFORMATION
LABORATORY CONDUCT PROCEDURES
The University of South Australia recognises its obligation to take all reasonable precautions to safeguard the health, safety and welfare of its staff while they are at work. The University of South Australia also believes that students leaving this University must take with them an attitude which accepts good health and safety principles as standard practice. To this end, the following Laboratory Conduct Procedures have been developed and must be adhered to by all who work in laboratories.
PERSONS WHO FAIL TO COMPLY WITH THESE PROCEDURES WILL NOT BE ALLOWED TO WORK IN THE LABORATORY
GENERAL SAFETY RULES
Eating, drinking and the application of cosmetics in laboratories are prohibited.
Do not store food and/or drink in laboratory refrigerators or laboratory storage units.
Do not run or indulge in horseplay.
No smoking in laboratories.
Do not leave open flames unattended. Open flames must not be used near any flammable solvents.
Chemical waste and radioactive substances should not be disposed of down sinks, drains or stormwater channels. Departments must provide suitable waste disposal containers and are responsible for removal by an approved waste disposal contractor. Waste containers must be clearly labelled to indicate waste content.
Keep fire evacuation routes clear at all times.
Be familiar with FIRE PROCEDURES within the laboratory.
Be familiar with the use of fire-fighting equipment.
Approved safety spectacles, goggles or safety shields must be worn in laboratories and all areas where tools or substances such as chemicals, liquids, UV light lasers or radiation may cause eye injury.
Laboratory coats or gowns tied at the back should be worn. Gloves should be worn at the discretion of the supervisor.
Wear closed-in footwear at all times. Bare feet, thongs and sandals are prohibited.
Cover all open wounds when handling chemicals and animals.
Wash hands after work and before leaving the laboratory.
Use disinfectants after handling suspected infectious materials.
Do not pipette by mouth, use mechanical pipetting devices.
Avoid lifting heavy objects – use trolleys where appropriate. Where lifting is unavoidable, seek assistance (share the load).
Do not use any machines or laboratory apparatus without pri
