Abstract: The industry standard YY/T 1274-2025 "Peritoneal Dialysis Equipment" was released in 2025 and is scheduled for implementation in 2027. This standard will replace YY/T 1493-2016, "Gravity-Controlled Peritoneal Dialysis Equipment" and YY/T 1274-2016, "Pressure-Controlled Peritoneal Dialysis Equipment". By comparing the main technical differences between the new edition and the previous editions, this paper interprets the key clauses of the new standard, aiming to provide references for the industry to understand and implement the standard, so as to improve the safety of peritoneal dialysis equipment and promote the high-quality development of the industry.
