Hose design factors need to be clearly identified and documented, supported by appropriate testing and verification. Hose design factors in line with ARPM standards are intended to provide clear guidance for the design, specification, fabrication and testing of subsequent hose assemblies and what can safely be expected for assembly usage. Fabricators and users of hose assemblies need a clear understanding of what they are specifying, purchasing and how it will perform. Market trends – manufacturers and importers are offering hose constructions that may not meet the Association of Rubber Products Manufacturers (ARPM) standards (listed on page 8) opening the door for a “buyer beware” environment. A list of definitions to clearly spell out what is meant by different terms or labels.List of guidelines for manufacturer hose labelling and associated documentation.Examples and test data illustrating the implications of hose design factors on advertised hose working pressures.Technical information on hose testing to clarify the differences between different design factors (e.g., 3:1, 4:1, 2:1) – and subsequent implications for hose assemblies.Definition of Hose Design Factors, what they mean, and implications for fabricators and end users of hose assemblies.It is intended to represent the consensus of contributing companies and organizations as to the recommended best practices regarding hose design factors, subsequent hose labelling, and implications for end user safety. This whitepaper represents an on-going effort to document best practices for ensuring safety and reliability of hose assembly applications.
