ISO 13043:2011 is restricted to refrigerant systems providing cooling or heating of passenger compartment, battery, etc., in passenger motor vehicles. It provides minimum design requirements for refrigerant containment and safety requirements of these systems. ISO 13043:2011 addresses the use of only R‑134a, R‑1234yf and R‑744 refrigerants in vehicle original equipment manufacturer (OEM) and…

ISO 294-5:2011 specifies a two-cavity mould (designated the type F ISO mould) for the injection moulding of 80 mm x 90 mm plates with a preferred thickness of 2 mm for single-point data acquisition because 2 mm has been found to provide the maximum anisotropic properties, with only a slight sensitivity to the rate of injection. For the design of plastic parts, this will provide upper and lower…
