ISO 10619-1-2017橡胶,塑料软管和管材.曲挠性和刚性的测量.第1部分:环境温度下的弯曲试验

This document specifies three methods for measuring the flexibility of rubber and plastics hoses and tubing (methods A1, B and C1), where the deformation of the hose or tubing is measured, and two methods for measuring the stiffness (methods A2 and C2) by measuring the force required to bend rubber or plastics hoses or tubing to a specific radius at ambient temperature. Methods A1 and A2 are suitable for rubber and plastics hoses and tubing with inside diameter of up to and including 80 mm. Method A1 allows the measurement of the flexibility of the hose or tubing by measuring the reduction in outside diameter when the hose is compressed between two plates. Method A2 provides a means of measuring the force required to reach a specific bend radius when the hose or tubing is compressed, as between two plates. The test can be carried out at a specified internal pressure. Method B is suitable for rubber and plastics hoses and tubing with inside diameter of up to and including 100 mm, and pr

ISO 10619-2-2021橡胶, 塑料软管和管材. 曲挠性和刚性的测量. 第2部分: 低于环境温度的弯曲试验

This document specifies two methods for measuring the stiffness and one method for the determination of the flexibility of rubber and plastics hoses and tubing when they are bent to a specific radius at subambient temperatures. Method A is suitable for non-collapsible rubber and plastics hoses and tubing with a bore of up to and including 25 mm. This method provides a means of measuring the stiffness of the hose or tubing when the temperature is reduced from a standard laboratory temperature. Method B is suitable for rubber and plastics hoses and tubing with a bore of up to 100 mm and provides a means of assessing the flexibility of the hose or tubing when bent around a mandrel at a specified subambient temperature. It can also be used as a routine quality control test. Method C is suitable for rubber and plastics hoses and tubing with a bore of 100 mm and greater. This method provides a means of measuring the stiffness of the hose and tubing at sub-ambient temperatures. This method is

ISO 10619-3-2011橡胶,塑料软管和管材.曲挠性和刚性的测量.第3部分:高温和低温下的弯曲试验

This part of ISO 10619 specifies a method for the determinationnof the bending characteristics of rubber and plastics hoses andntubing, including the force required for bending, over a range ofntemperatures from −60 ºC to +200 ºC. The nature of the apparatus,nhowever, limits its applicability to rubber and plastics hoses andntubing of small internal diameter, i.e. up to 12,5 mm.

This Uganda Standard specifies two methods for measuring the stiffness and one method for the determination of the flexibility of rubber and plastics hoses and tubing when they are bent to a specific radius at sub-ambient temperatures. Method A is suitable for non-collapsible rubber and plastics hoses and tubing with a bore of up to and including 25 mm. This method provides a means of measuring the stiffness of the hose or tubing when the temperature is reduced from a standard laboratory temperature.

This Uganda Standard specifies a test method for measuring the low-temperature brittleness of rubber and plastics hoses with a textile reinforcement and tubing at sub-ambient temperatures by crushing a test piece of the hose. This Standard is only applicable to hoses with a nominal bore up to and including 100 mm.

GSO ISO 10619-1-2013橡胶和塑料软管和管材.柔韧性和刚度的测量.第1部分：环境温度下的弯曲试验

This part of ISO 10619 specifies three methods for measuring the flexibility of rubber and plastics hoses and tubing (methods A1, B and C1), where the deformation of the hose or tubing is measured, and two methods for measuring the stiffness (methods A2 and C2) by measuring the force to bend the hose or tubing when rubber or plastics hoses or tubing are bent to a specific radius at ambient temperature. Methods A1 and A2 are suitable for rubber and plastics hoses and tubing with inside diameter of up to and including 80 mm. Method A1 allows the measurement of the flexibility of the hose or tubing by measuring the reduction in outside diameter when the hose is compressed between two plates. Method A2 provides a means of measuring the force required to reach a specific bend radius, when the hose or tubing is compressed, as between two plates. The test can be carried out at a specified internal pressure. Method B is suitable for rubber and plastics hoses and tubing with inside diameter of up to and including 100 mm, and provides a means of assessing the behaviour of the hose and tubing when bent around a mandrel. The final mandrel diameter used can be taken as the minimum bend radius of the hose or tubing. As this value is determined by the reduction of the outside diameter which can be used as a measure of the flexibility of the hose or tubing. The hose or tubing being tested can be unpressurized, pressurized or under vacuum and, if required, with the curvature or against the curvature of the hose or tubing, if such curvature is present. Methods C1 and C2 are suitable for rubber and plastics hoses and tubing with inside diameter of 100 mm and greater. Method C1 provides a means of determining the flexibility of the hose and tubing at the minimum bend radius. Method C2 provides a method of measuring the stiffness of the hose and tubing at the minimum bend radius.
