Among the following rolled part faults, the exterior cracking defect cannot be considered a rolled part defect. It must be reported as such.
All other rolled part defects are lies. They are false indications that cause damage to reporting systems and prevent parts from being reported as defective.
Examples of lying defects include but are not limited to: pits, holes, breaks, and stains. These defects appear on rolling equipment and lead to false reports by causing lights to go off or sensors to detect non-defective parts. This can result in bad quality parts being shipped.
Lying defects can be anything that causes a light or sensor to report an otherwise good part as defective. False alarms can also be caused by incorrectly calibrated or damaged sensors. Lying defects should be reported even if they are only suspected to exist on a part. For example, if a hole is found on a finished product, it should still be reported even if it does not affect the function of the part.
Lying defects can be internal or external to the part. Examples of internal lying defects include voids inside molded parts or cracks within wooden products. External lying defects include paint defects on metal parts, soil contamination on agricultural products, and insect damage on fruit and vegetables.
Defects are characteristics of the job that do not conform to the contract. Defects can emerge as a result of design flaws. Deficiencies in materials used during construction may cause defects. So too may errors made by inexperienced contractors.
For example, if an interior wall is not insulated properly, it will be cold to the touch. This is a defect because it violates the specifications of the plan. It could also be a defect if wood is used instead of insulation material. The quality of wood varies, so if it's found to be defective, it should be replaced rather than just covered up.
Some defects are more serious than others. For example, if a hole in a roof causes water to leak into the home, this is referred to as a structural defect. If, however, there is no damage to other parts of the house and if the hole isn't too large, it may not need to be repaired until later. At that time, patching or otherwise fixing the hole would be considered remedial work.
Remedial work is usually done under the category of painting or siding. However, any work that needs to be done to the structure itself is considered structural repair. These repairs include replacing damaged elements such as windows, doors, roofs, and chimneys.
A manufacturing flaw is a fault in a product that was not intended in the law of products liability. This type of fault happens when a product deviates from its original design and is more risky than users anticipate. Injuries and accidents (tort law) caused by manufacturing flaws are usually covered by product liability laws or insurance policies.
Examples of manufacturing defects include broken or improperly secured knives, spoons, or forks in a restaurant meal service line; buttons that pop off clothes due to poor sewing techniques; and lace that has been torn or otherwise damaged during production.
Manufacturing defects can be either structural or non-structural. Structural defects are those that affect the product's strength or quality. For example, if a knife blade is too thin, it may break easily. If a spoon is made from plastic rather than stainless steel, it will not last as long or perform as well under normal use conditions. Non-structural defects do not affect the product's strength or quality but may still cause damage if used with other properly functioning products. For example, if a button pops off a shirt during manufacture, it cannot then be used as an indicator of size so shoppers would have no way of knowing how many holes need to be worn in a t-shirt for it to fit them correctly.
Structural defects can be found using physical tests.
