Product Quality Control: Methods and Procedures
What are the Products?
There are tangible assets that possess unique characteristics and meet the needs of targeted consumers.
What Information Must the Product Description Include?
- Title or name of the product
- Applications of the product
- Good manufacturing conditions, installation, storage, and use
- Physical characteristics
- Features of reliability
- Maintainability characteristics
- Test methods and criteria for acceptance
- Packaging and protection of the product
- Service information number and aftermarket
What is Quality Control?
Quality control is the process by which rules are established and enforced to ensure compliance with the specifications of both the final product and the product throughout the production process.
What are the Steps in Quality Control?
- Establish what is to be controlled.
- Choose a unit of measurement.
- Set the normal value or standard specifications to control.
- Set a measuring instrument.
- Perform measurement magnitude in the chosen unit.
- Interpret the differences between actual and normal value or standard.
- Act on the differences.
What is Inspection?
Inspection is the assessment of the quality of a product feature.
What are the Methods of Inspection?
Define each of them:
- Inspection of discrete units of product: independent.
- Inspection of parts of a mass of a sample being tested: a wine Cuba.
How is the Product Lot-Shaped?
A lot is a set of units of product produced under uniform conditions.
When Can the Intensity of Inspection be 100%?
When it comes to critical products, inspection of large samples, inspection for small samples, and do not inspect.
Explain Inspection Sampling
Inspection sampling is a process of evaluating a randomly chosen part of a product contained in a batch to accept or reject the entire lot. The main advantage is economy. A sampling plan is required to determine lot size, the sample size, and acceptance number.
Benefits of Inspection Sampling
- Economy
What is Needed for Inspection Sampling?
A sampling plan is required to determine lot size, the sample size, and acceptance number.
When Implementing Self-Inspection?
Self-inspection is implemented in the manufacturing processes themselves by enforcement personnel, so operators perform their own inspection operations in their manufacturing jobs.
When Can Self-Inspection be Implemented?
If there are various circumstances:
- If the saturation time of the manufacturing operator allows them to perform the inspection without neglecting their responsibilities.
- If the operator training is sufficient or can be purchased for the inspection.
- If it is possible to use measuring equipment in the workplace.
- If the inspection results cannot adversely affect the wages, work, or personal performance assessment.
Quality in Storage and Expeditions
- Observe the specifications for storage and maintenance.
- Provide the means necessary to prevent product deterioration.
- Set appropriate methods for products in and out of storage areas.
- From time to time, assess the conservation status of the products.
- Apply appropriate packing media.
