Introduction
Organic coated aluminium and aluminium alloy strip and sheet products can be used to advantage in
cases where corrosion resistance and decorative appearance are of primary importance. They have
applications throughout the flat products processing industry e.g. in the building, automotive, caravans,
appliances, fabricating and packaging industries.
Organic coated aluminium and aluminium alloy flat products can be delivered in numerous types and
grades, depending on the base material used (various grades of aluminium), on the coating material and
types of coating and on the requirements for the surface appearance and the formability.
The properties of the products can vary within greater or smaller limits depending on the choice and
combination of properties required. It is therefore not practicable to specify in detail minimum
requirements for all properties for all types of products.
As a general rule, material specifications are agreed between manufacturer and user/purchaser using,
when appropriate, the guidelines from Annex C.
Guidelines for proper storage and subsequent processing of organic coated aluminium and aluminium
alloy flat products are given in Annex D.

European foreword
This document (prEN 1396:2022) has been prepared by Technical Committee CEN/TC 132 “Aluminium
and aluminium alloys”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1396:2015.

Introduction
Organic coated aluminium and aluminium alloy strip and sheet products can be used to advantage in
cases where corrosion resistance and decorative appearance are of primary importance. They have
applications throughout the flat products processing industry e.g. in the building, automotive, caravans,
appliances, fabricating and packaging industries.
Organic coated aluminium and aluminium alloy flat products can be delivered in numerous types and
grades, depending on the base material used (various grades of aluminium), on the coating material and
types of coating and on the requirements for the surface appearance and the formability.
The properties of the products can vary within greater or smaller limits depending on the choice and
combination of properties required. It is therefore not practicable to specify in detail minimum
requirements for all properties for all types of products.
As a general rule, material specifications shall be agreed between manufacturer and user/purchaser
using, when appropriate, the guidelines from Annex C.
Guidelines for proper storage and subsequent processing of organic coated aluminium flat products are
given in Annex D.
