Aerospace series - Test methods for transparent materials for aircraft glazing - Part 12: Determination of linear thermal expansion

DS/EN 2155-12-1998 发布历史

This standard specifies the method to determine the reversible linear thermal expansion of plastics with exclusion of changes in length due to accidental factors such as changes in moisture content, degree of polymerization and stress release. Since it will not be possible to exclude all these accidental factors, the method can be expected to give only approximate values.
