1.1 General This International Standard provides and describes the usual procedures for the preparation of component surfaces prior to bonding for either laboratory evaluation or the process of construction. This International Standard is applicable to metal and plastic surfaces that are commonly encountered. 1.2 Surfaces These comprise the following metal, metal-alloy and plastic families — the last-mentioned including filled versions and suitable paints: Metals and metal alloys aluminium chromium copper magnesium nickel steel (mild) steel (stainless) tin titanium zinc Paints cataphoretic (water-based) poly-alkyd ester epoxide urethane Plastics Thermoplastic acrylonitrile-butadiene-styrene copolymer poly-acetal acrylate amide butylene terephthalate carbonate ester ether ether ketone ethylene imide methyl methacrylate phenylene oxide propylene styrene sulfone tetrafluoroethylene vinyl chloride Thermoset cellulose-based esters poly-alkyd allyl phthalate amino epoxide ester phenolic urethane urea-based (see poly-amino above) 1.3 Methods The various techniques described for cleaning and modifying surfaces are drawn from the best of current practice. The methods can be used in a variety of combinations to create the most effective preparative process conducive with the environmental durability required of the bonded joint.
