Shandong provincial standards for plastic runway went into effect recently. Many of the terms are even stricter than those of the existing national standards.

The local standard contains specifications for the use of raw materials, construction requirements, acceptance requirements and maintenance specifications. A positive list of raw materials that can be used for the production of plastic runways is also included.

“There is a more specific positive list for the construction process of plastic runways in middle and primary schools,”said Wang Weishan, director of Shandong provincial packaging and material safety testing center, “The list will ensure the source of raw material. And it is initiated by Shandong province.”

The Shandong standards stipulate the harmful substances of raw materials and set limit of their use. Among them, the limit for benzene is 2.5 times stricter than the national standard. And for the first time nationwide, Shandong puts forward solvent-free construction.
