Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 20974-2007 "rigid phenolic foam insulation products (PF)". This standard and GB/T 20974-2007
Compared to the main changes are as follows.
--- Cancellation terms according to the density genotyping;
--- Increasing the appearance requirements for products;
--- Increase the size deviation requirements, increasing the requirements flatness, straightness and squareness;
--- Combustion properties increased oxygen index and smoke density requirements of the class;
--- Improving the bending fracture strength requirements;
--- For products increased wall perpendicular to the plate surface tensile strength requirements;
--- Improve the thermal conductivity requirements;
--- Improve the water absorption volume (V/V) requirements;
--- Modify the permeability coefficient of the requirements;
--- Inhabited for long-term indoor environmental products increased formaldehyde emission requirements;
--- Modify the decision rule.
