National Institute of Standards and Technology. Canadian Council of Independent Laboratories. A glossmeter also gloss meter is an instrument which is used to measure specular reflection gloss of a surface. Geosynthetic Institute Test Methods and Standards.
National Concrete Masonry Association.
Illuminating Engineering Society of North America. Instruments are available to quantify orange peel by measuring distinctness of image DOI or reflected image quality RIQ and haze.
The interval of checking this calibration is dependent on the frequency of use and the operating conditions of the glossmeter. Views Read Edit View history. There are a number of different geometries available for gloss measurement, each being dependent on the type of surface to be measured. Three types of instruments are available on the market: Two high gloss surfaces can measure identically with a standard glossmeter but can be visually very different.
International standards state that it is the tile that is the calibrated and a traceable artefact not the glossmeter. However it is often recommended by manufacturers that the instrument also be checked to verify its operation on a frequency dependent on the operating conditions.
Each glossmeter is set up by the manufacturer to be linear throughout its measuring range by calibrating to a set of master calibration tiles traceable to BAM Federal Institute for Materials Research or similar organisations. Florida Concrete and Products Association. Organisation for Economic Co-operation and Development. International Organization for Standardization. World 64, 35 ; Paper 27, 18 Feb. This standard tile has assigned gloss unit values for each angle of measurement which are also traceable to National Standards such as BAM Federal Institute for Materials Research.
Ministere des transports du Quebec MTQ. From Wikipedia, the free encyclopedia.
Society of Automotive Engineers. Gloss is determined by projecting a beam of light at a fixed intensity and angle onto a surface and measuring the amount of reflected light at an equal but opposite angle.
In Hunter, as part of a research project for the U.

67503 automotive industry is a major user of ein glossmeter, with applications extending from the factory floor to the repair shop. However, it is not sensitive to other common effects which reduce appearance quality such as haze and orange peel. Transportation Association of Canada. The glossmeter is adopted by many industries, from paper mills to automotive and is used at each stage of the manufacturing process from goods receipt through to final inspection.
Many industries use glossmeters in their quality control to measure the gloss of products to ensure consistency 67503 their manufacturing processes. Early work in by Pfund  led to the development of a variable angle “glossimeter” to measure specular gloss which was later patented in The Glarimeter – An instrument for measuring the gloss of paper, J.
Standard DIN 67530
International Slurry Surfacing Association. The angle is selected based on the anticipated gloss range, as shown in the following table. The instrument is calibrated to this checking standard which is commonly referred to as a ‘calibration tile’ or ‘calibration standard’. Insulating Cable Engineers Association.
Two additional angles are used for other materials. Physical tests of varnishes, Proc. Of the many internationally recorded publications relating to gloss measurement, the earliest recorded studies perceived and instrumental are attributed to Ingersoll,  who in developed a means to measure the glare of paper.
Metals have a much higher reflection and are therefore less angularly dependent. Reflected light was measured 6530 a pyrometer lamp as a photometer. In order to maintain the performance and linearity of the glossmeter it is recommended to use a checking standard tile. National Council Highway Research Program. Code of Federal Regulations. DIN Drainage channels for vehicular and pedestrian areas.
American Water Works Association. American Society of Civil Engineers. ASTM has a number of other gloss-related standards designed for application in specific industries. National Bureau of Standards, produced a paper on the methods of determining gloss.
