Unit Summary
In this unit pupils will develop technical principles knowledge with an explicit focus on exam technique.
Lesson Summary
You will learn to identify and explain different Quality Control methods to check that a product meets its specifications.
Key Notes
- Quality Control is about checking products against standards.
- There are a range of Quality Control methods that go beyond visual inspections.
- Depending on the product, some Quality Control methods are more appropriate than others.
Vocabulary To Learn
- Quality Control (QC): checks made on a product before, during and after its production, so it meets quality and safety standards
- technical specification: a detailed description of a product's requirements and features
- tolerance: the acceptable range of variation in a product's measurements
- standardised component: a part that's made the same way every time so it can be used in a range of products
Common Mistakes To Avoid
- Quality control is only about looking at the product at the very end of production.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Quality Control is about checking products against standards. There are a range of Quality Control methods that go beyond visual inspections.
2. What does this key word mean in this lesson? 'Quality Control (QC)'
checks made on a product before, during and after its production, so it meets quality and safety standards.
3. Correct this common mistake.
Mistake: Quality control is only about looking at the product at the very end of production. Correction: Quality Control can happen throughout production (in-process checks, sampling, functional tests), not just at the end.
