美国材料试验协会D 522 Standard Test Methods for Mandrel Bend Test of Attached Organic Coatings
国际标准化组织 6860 油漆和清漆 – Bend test (conical mandrel)
锥形芯轴测试仪
介绍
The varying mandrel diameter (3.2 毫米 – 38.1 毫米) stretches a coating
through a gradient of distension, allowing precise determination of adhesion characteristics.
1.Panels up to 20 cm and 1.6 mm thickness can be tested
2.Durable sturdy stainless steel mandrel
程序
– Cover test panel with paper between mandrel and draw bar and clamp the probe.
– Fold the panel around the cone by using the manually operated arm.
– Bend uniformly at 180 degrees within 15 秒.
– Remove panel and examine the coating for cracks.
– Mark the point at which the cracking stops.
– Measure the distance from the farthest end of the crack to the small end of the mandrel.
– Appropriate calibration curves also permit determination of the elongation values of the paint film.
