JB/T10443 Specification for laminated paperboard is divided into three parts: Part 1: Definitions, classification and general requirements: Part 2: Test methods: Part 3: Specification for single material Specification for laminated pre-pressed paperboard - Type LB3.1.1, LB3.1.2, LB3.3.1 and LB3.3.2. This part is the first part of JB/T10443. This part is formulated for the first time.
This part is modified to adopt the International Electrotechnical Commission (IEC) publication IEC60763-1:1983 "Specification for laminated paperboard Part 1: Definitions, classification and general requirements" (English version). The main difference between this part and IEC60763-1:1983: According to the requirements of GB/T1.1-2000, the chapter "Normative Reference Documents" is added. This difference has been compiled into the text and marked with a single vertical line in the blank space of the corresponding clause. This part was proposed by the China Machinery Industry Federation. This part is under the jurisdiction of the National Technical Committee for Standardization of Insulating Materials.

3 Terms and definitions
The following terms and definitions apply to this part. 3.1
Pressboard
Paperboard made of high chemical purity pulp from plant raw materials, usually made on intermittent paperboard machines, characterized by high density, uniform thickness, smooth surface, good mechanical strength, softness and electrical insulation properties. To meet certain purposes, the surface may have a reticulated pattern. 3.2
Laminatedpressboard
Paperboard made by bonding several sheets of paperboard with an adhesive. 4 Classification
Based on the components and properties, this section lists various types of laminated paperboard in Table 1. The model uses the same model as the paperboard in JB 8989.1, but with "L" to indicate lamination (e.g. LBO.1). Table 1 Classification

5.1 Components
Single paperboard used to make laminated paperboard shall meet the requirements of the corresponding paperboard in JB/T8989.1, except that the thickness is not required to meet the requirements. Laminated paperboard should be made by laying paperboard in the same direction and bonding it with a suitable adhesive. If the adhesive is changed, the purchaser should be notified in time.
Note: If the structure of the laminated paperboard is not laid in the same direction, it should be specially stated. 5.2 Surface state
The surface of the paperboard should be calendered or have a reticulated pattern.
5.3 Machinability
The paperboard should be able to be machined with the tool recommended by the manufacturer suitable for its processing. 6 Size
Preferred thickness is 10mm, 12mm, 15mm, 20mm, 25mm, 30mm, 40mm50mm, etc. as specified in the GB/321 series.
Supply conditions
Paperboard packaging should ensure adequate protection during transportation, loading and unloading and storage. 8 Marking
Delivered paperboard should be clearly and permanently marked with the following: a) Manufacturer's name or trademark;
Paperboard type, such as LB2.1, LB4.3: b)
Nominal thickness:
