Features: This standard is revised based on imported prototype machines and the actual production and usage status of centrifugal molding machines for cement products in China. It expands the scope of application (all centrifugal molding surfaces of centrifugally molded cement products), facilitating its promotion and implementation in China. This standard replaces JC/T822——1988（1996）. The main differences between this standard and JC/T822-1988（1996） are as follows:
— Revised the scope of the standard (1988 edition, section 1; current edition, section 1)
— Revised the notation for referenced standards (1988 edition, section 2; current edition, section 2)
— Removed product classification (1988 edition, section 3)
— Revised technical requirements (1988 edition, section 4; current edition, section 3)
— Revised test methods (1988 edition, section 5; current edition, section 4)
— Revised inspection rules (1988 edition, section 6; current edition, section 5)
— Revised marking, packaging, storage, and transportation (1988 edition, section 7; current edition, section 6)
— Added (see section 3.2)
— Added test requirements for the static balance of the support roller (see section 3.3.3.5)
— Added requirements for the connection of the support roller and the cone sleeve with a key (see section 3.4.1.3)
— Added requirements for the parallelism tolerance of the common axis of adjacent support rollers (see section 3.5.2)
— Added requirements for the deviation of the wheel spacing of the support roller (see section 3.5.4)
— Added requirements for appearance quality (see section 3.6)
— Added a normative appendix "Product Model" (see Appendix A)
