This European Standard specifies the requirements for and methods of testing of organic coatings which are applied to metallic process engineering equipment that will come in contact with chemical substances (liquids, solids and gases). The requirements specified here may be used for the purposes of quality control (e.g. as agreed between the contract partners or been given by national regulations). The standard does not cover coatings as in EN ISO 12944-1, but it does apply to coatings which serve one or more of the following purposes: — to protect the component from adverse effects of aggressive substances; — to protect waters (e.g. ground water) against hazardous substances; — to protect the charge from becoming contaminated by components released from the substrate material; — to achieve a particular surface properties. * The described coatings are to be used for metallic process engineering equipment that will come in contact with chemical substances. The different coating systems are: — laminate coating systems which contain cold-curing resins; — trowelled coating which contain cold-curing resins; — sprayed coating systems which contain resins (in special cases, such coatings may also be applied by brushing, rolling, flow coating, dipping, or by other means, such as providing sleeving for nozzles); — powder coating systems which contain organic materials (powder coatings may be used as corrosion pro¬tection or for non-stick purposes). For design and preparation of substrate see EN 14879-1.

操作套筒顶部的V型槽允许对圆柱形物体进行可靠的测量。将探头固定在操作套筒上,并放在要测量的物体上。注意:传感器配有坚硬、耐磨的探头杆。但是,应避免在粗糙和坚硬的表面上滑动探头,例如抛丸表面。minitest 1100–2100-3100-4100系列探头先前系列的所有探头都与涂层测厚仪Minitest 2500和Minitest 4500兼容。但是,需要执行传感器与测量电子设备的一次性自适应。...
