Regardless of the gloss level of the surface of a product, the manufacturer has to ensure that there is consistency in meeting the designed engineering requirements. For a product of high gloss, such as a motor vehicle, customer's perception of uniform gloss throughout the car body is critical, whereas for military vehicles it would be more beneficial to have a matt finish to avoid detection, For this reason, quality control requires a high degree of accuracy. Gloss limit standards are acceptable tolerance levels as defined by the user allowing them to compare readings to pre-defined values or approved samples (standards) this allows the user to ensure that the product and parts have consistency, on a car production line for example.Using the Elcometer 480 Glossmeter, you can save and store up to 40 different limit standards that consist of the nominal or target value that is required for readings and differential, low and high limits for gloss and haze. This then allows the user to take a reading that they deem as "good" and ensure the following samples meet the same standard.
