This standard specifies quality standards and test methods for four types of rigid foam plastics used for building insulation. This standard covers rigid foam plastics in the form of flat or shaped plates and includes processed or unprocessed surfaces. It also includes surfaces laminated with other plastics or thin layers in the form of metal films, inorganic coatings, paperboard, etc. This standard does not apply to materials for insulation of containers and pipes and to shock sound absorbing or sound insulating materials. This standard does not apply. is a rigid foam plastic for building insulation, covering the following materials: EPS Based on expandable polystyrene. XPS Based on extruded polystyrene. Based on PUR polyurethane. Based on PF phenolic resin. .The quality standard values of this standard are used only as material specifications between the manufacturer and the purchaser and are not used for design purposes. In case of application for special purposes, additional requirements shall be determined by agreement between the manufacturer and the purchaser in accordance with the requirements set in this standard.
