After my lunch and i will continue share BS ISO 10928:2009,Plastics piping systems – Glass-reinforced thermosetting plastics (GRP) pipes and fittings – Methods for regression analysis and their use.
It is not very easy for me to find this standard.Some of my friend helped me a lot.
BS ISO 10928:2009 describes the procedures intended for analysing the regression of test data,usually with respect to time and the use of the results in design and assessment of conformity with performance requirements. Its applicability is limited to use with data obtained from tests carried out on samples. The referring standards require estimates to be made of the long-term properties of the pipe for such parameters as circumferential tensile strength, long-term ring deflection, strain-corrosion and creep or relaxation stiffness.
The referring standards specify limiting requirements for the long-term properties and performance of aproduct. Some of these are based on destructive tests, for example hoop tensile strength whilst others are based on actual or derived physical properties, such as creep or relaxation stiffness.
