Описание (английский):

This International Standard describes a test procedure for assessing the protection offered by coatings of paints or varnishes on aluminium and aluminium alloys against corrosion arising from a scribe mark cut through the coating, when the coated panel is subjected to a test regime of alternate immersion in and removal from a dilute salt solution.

Overview

ISO 15710:2002 is an international standard developed by the International Organization for Standardization (ISO) that specifies a test method for evaluating the corrosion resistance of paints and varnishes applied to aluminum and its alloys. The standard focuses on corrosion testing by subjecting coated panels, featuring a deliberate scribe mark cutting through the coating, to alternate immersion in and removal from a buffered sodium chloride (salt) solution. This method simulates the aggressive environmental conditions that coatings may encounter, especially in aerospace applications, and helps determine their protective performance against corrosion initiated at coating breaches.

Key Topics

Scope and Purpose
The standard defines a practical and reproducible laboratory procedure to assess how effectively coatings protect aluminum substrates from corrosion at scribed locations during cycling between immersion in saline solution and exposure to high humidity air.

Test Solution and Conditions
The test solution consists of sodium chloride buffered with phosphate disodium and boric acid at a precise pH of 8±0.2. The test panels undergo alternating 2-hour cycles of immersion in this solution at 35°C followed by 2 hours of exposure to greater than 80% relative humidity.

Test Panels and Preparation
Aluminum test panels are prepared and coated per related ISO standards, with edges and backs coated with an inert or equivalent protective layer. Two perpendicular scribe marks are made on each panel to expose the bare metal. The depth and width of the scribe are controlled to ensure consistency.

Testing Apparatus
Equipment includes an enclosure that controls temperature and humidity and supports automated vertical cycling of panels into and out of saline solution baths, ensuring uniform and repeatable exposure.

Evaluation and Reporting
Corrosion around the scribe is periodically assessed according to ISO degradation criteria. After test completion, panels are rinsed and dried before final examination. The test report must include product identification, reference to ISO 15710, test conditions, solution preparation details, scribing method, and corrosion observations.

Applications

ISO 15710:2002 is highly applicable for:

Aerospace Industry
Aircraft coatings often face rapidly changing environmental conditions, including salt exposure and humidity fluctuations at altitude. This standard’s test method provides valuable insight into the durability and corrosion resistance of aerospace-grade paints and varnishes.

Quality Control and Product Development
Manufacturers of protective coatings can utilize this standard to verify coating performance consistency, compare new formulations, and support certification processes.

Research and Comparative Studies
Allows controlled laboratory simulation of complex environmental stresses with reproducible parameters, facilitating comparative corrosion resistance studies of different coating systems under saline mist and immersion cycling.

Related Standards

The ISO 15710:2002 procedure references and complements several other ISO standards, including but not limited to:

ISO 1513 – Sample preparation and examination for paint and varnish testing

ISO 1514 – Standard test panels for paints and varnishes

ISO 2808 – Measurement of dry film thickness of coatings

ISO 3270 – Conditioning and testing temperature and humidity requirements

ISO 3696 – Specifies analytical grade water quality required for test solutions

ISO 4628-1 & ISO 4628-8 – Evaluation and classification of coating degradation and corrosion around scratches

These related standards define essential preparatory and evaluative methods ensuring consistent implementation of the corrosion test.

ISO 15710:2002 establishes a standardized and reliable alternate immersion corrosion test that safeguards coating performance in saline environments, proving indispensable for industries demanding high corrosion resistance, such as aerospace and automotive coatings. Its controlled laboratory approach aids manufacturers, researchers, and engineers in the development, validation, and quality assurance of protective paint and varnish systems on aluminum substrates.
