The Rubber Manufacturers Association (RMA), now known as the Association for Rubber Products Manufacturers (ARPM) since its rebranding in 2020, serves as a pivotal trade association for manufacturers of rubber products in the United States and across North America. This organization plays a crucial role in establishing technical standards and engineering guidelines that are widely adopted within the rubber industry, particularly for products such as belts, hoses, gaskets, seals, and other industrial rubber goods. The ARPM's standards are vital for ensuring consistency, safety, and performance in rubber product manufacturing and usage.
ARPM publishes several significant standards, including IP-20 for classic V-belts, IP-22 for narrow V-belts, IP-24 for synchronous belts, and IP-26 for Poly-V belts. These standards help engineers and manufacturers select the appropriate belts for specific applications and ensure that they meet industry requirements. Additionally, ARPM provides hose standards that cover a variety of applications such as hydraulic, industrial, and material handling hoses. The organization also produces the Power Transmission Belt Handbook, which is considered the definitive reference for belt drive engineering in North America, containing essential design procedures and power rating tables that facilitate effective belt drive system design.
The development of ARPM standards involves collaboration between technical committees composed of both manufacturers and users, ensuring that the guidelines reflect practical industry needs. These standards are recognized by the American National Standards Institute (ANSI), further legitimizing their importance in the industry. In Mexico and throughout Latin America, ARPM/RMA standards are frequently utilized alongside ISO and DIN standards as primary references for selecting belts and designing drive systems. Leading belt manufacturers, such as Gates, Continental, and Optibelt, reference ARPM standards in their product catalogs, underscoring their relevance and authority in the market.
