Method 1220B corresponds to method B (Regression with time as the independent variable) of EN 705:1994. Method 1220C
10、 corresponds to method C (Second order polynomial relationships) of EN 705:1994. These methods are incorporated into BS 2782 for association with related test methods for plastics materials and plastics piping components. This test method has been prepared for reference by other standards under prep
11、aration by CEN for specification of reinforced plastics piping systems and components. It has been implemented as a national standard to enable experience of the method to be gained and for use for other fresh applications. It is also for use for the revision or amendment of other national standards
