Electrodeposited metallic coatings and related finishes - Sampling procedures for inspection by attributes (ISO 4519:1980)
The sampling plans are applicable to the inspection of end items, components, materials in process and finished products in storage. The plan are intended to be used for a continuing series and lots, but they may also be used for isolated lots. ISO 4510 is not applicable to the sampling and testing of mechanical fasteners having electrodeposited metallic coatings or related finishes. These sampling plans are based on AQL's of 1,5 and 4,0 %.

Galvansko nanašanje kovinskih in sorodnih prevlek - Naključno vzorčenje za kontrolo kakovosti (ISO 4519:1980)
Ta mednarodni standard vzpostavlja načrte in postopke vzorčenja za kontrolo galvanskih nanosov kovinskih prevlek po opisnih spremenljivkah. Uporablja se lahko za sorodne prevleke po dogovoru med dobaviteljem in kupcem. Temelji na standardu ISO 2859 (glej tudi dodatek 1 k standardu ISO 2859). Načrti vzorčenja v tem mednarodnem standardu se med drugim uporabljajo za kontrolo končnih izdelkov, komponent ter materialov v predelanih in končnih skladiščenih izdelkih. Načrti so namenjeni predvsem za uporabo v trajnih sklopih serij, vendar se lahko uporabljajo tudi za kontrolo izoliranih sklopov. Vendar je zagotovilo za izolirane sklope manjše od tistega za trajne sklope serij. Ta mednarodni standard se ne uporablja za vzorčenje in preskušanje mehanskih veznih elementov z galvanskim nanosom kovinskih ali sorodnih prevlek v vseh okoliščinah, katerih postopki za te komponente so določeni v standardu ISO 3269. Načrti vzorčenja v tem mednarodnem standardu temeljijo na 1,5- in 4-odstotni prevzemni meji kakovosti1). Druge prevzemne meje kakovosti se lahko uporabljajo, če so določene v specifikaciji izdelka, pri čemer je treba upoštevati standard ISO 2859 in dodatek 1 tega standarda. Poleg tega je načrte vzorčenja mogoče oblikovati tudi na podlagi kontrole po številskih spremenljivkah.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards institutes (IS0 member bodies). The work of developing Inter-
national Standards is carried out through IS0 technical committees. Every member
body interested in a subject for which a technical committee has been set up has the
right to be represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council.
International Standard IS0 4519 was developed by Technical Committee ISO/TC 107,
Meta//ic and other non-organic coatings, and was circulated to the member bodies in
March 1979.
It has been approved by the member bodies of the following countries :
Bulgaria Israel South Africa, Rep. of
Canada Italy Spain
Czechoslovakia Japan Sweden
France Korea, Rep, of Switzerland
Germany, F. R. Libyan Arab Jamahiriya Turkey
