ISO 9717-2010 pdf free.Metallic and other inorganic coatings – Phosphate conversion coating of metals.
ISO 9717 specifies requirements for the processing of ferrous metals, aluminium, zinc, cadmium and their alloys to produce coatings consisting essentially of inorganic phosphates, which are intended to be used in conjunction with supplementary treatments for the protection of the basis metal against corrosion and to provide anti-wear properties to sliding surfaces, adhesion to organic finishes and ease of cold-forming operations.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1463, ISO 2064, ISO 2080, ISO 2819, ISO 9587 and ISO 9588 and the following apply.
free acid of a phosphating solution
number of millilitres of 0.4 % mass fraction of sodium hydroxide solution required to neutralize 10 ml of the phosphating solution to pH 4. using methyl orange or an equivalent indicator system
3.2 pointage measure of the total acidity of a phosphating solution, i.e. the number of millilitres of 0,4 % mass fraction of sodium hydroxide solution required to neutralize 10 ml of the phosphating solution to pH 10 using phenolphthalein as an indicator
3.3 accelerated process process where the processing solution is of the metal phosphate/phosphoric acid type containing additions such as oxidizing agents, e.g. nitroguanidine, nitrate, nitrite, or chlorate, which accelerate the coating formation
3.4 unaccelerated process process where the processing solution is of the plain metal phosphate/phosphoric acid type and no accelerating agents are employed
3.5 sealing application of a supplementary coating to the phosphate surface immediately after phosphating, rinsing and drying, to form a complete protective or Iubncation system.ISO 9717 pdf free download.
