For specialized applications, consult the Technical Services Department for advice. Thermal Movement Coefficient of linear expansion 0.5 x 10 -4 / o C temperature rise, i.e. 1mm per 2m length for a temperature rise of 10 o C. An allowance is made for expansion of pipes and pipe fittings in each socket. Effect of Solar Radiation Prolonged exposure to sunlight will cause the colour to fade. It may also result in slight loss of impact strength. We would not expect this to seriously affect the performance of the system. Effect of Frost Frost does not affect the performance of the system. However, impact strength is
