Ethanol Resistance Tester

The Ethanol Resistance Tester is designed to evaluate the durability and chemical resistance of materials when exposed to ethanol under controlled laboratory conditions. It provides objective data on visual, physical, and chemical changes, helping manufacturers and researchers predict material performance, ensure quality control, and guide product development for applications where ethanol contact may occur.

Application

(1) Evaluating the resistance of coatings, paints, inks, and surface finishes to ethanol exposure.

(2) Assessing the ethanol resistance of plastic components and polymer materials.

(3) Testing materials for automotive interiors, fuel systems, and electronic devices.

(4) Quality control to ensure materials meet specified ethanol resistance standards.

(5) Research and development of new materials and surface treatments with improved ethanol resistance.

(6) Predicting the lifespan and performance of materials under ethanol exposure.

(7) Comparing material performance for selection of suitable products in ethanol-containing environments.

Standards

(1) ASTM D1308 – Standard Test Method for Effect of Household Chemicals on Clear and Pigmented Organic Finishes.

(2) ASTM D543 – Standard Practices for Evaluating the Resistance of Plastics to Chemical Reagents.

(3) ISO 2812-1 – Paints and Varnishes – Determination of Resistance to Liquids – Part 1: Immersion Method.

(4) ISO 2812-4 – Paints and Varnishes – Determination of Resistance to Liquids – Part 4: Spotting Method.

Features

(1) Provides standardized testing for immersion, spot, and wipe (rub) methods.

(2) Test containers or chambers made of ethanol-resistant materials to prevent leakage and evaporation.

(3) Fixtures or racks for securely holding specimens during immersion tests.

(4) Spot test accessories such as watch glasses or sealing films for controlled ethanol exposure.

(5) Mechanical wiping/rubbing device to apply controlled force, speed, and stroke numbers with ethanol-saturated media.

(6) Temperature control system for maintaining specified exposure conditions.

(7) Timer for precise control of test durations.

(8) Standardized visual inspection area for evaluating specimen changes.

(9) Optional equipment for quantitative evaluation: gloss meters, colorimeters, hardness testers.

(10) Compact, robust design suitable for laboratory environments.

Parameters

Accessories

(1) Test containers or chambers resistant to ethanol.

(2) Specimen racks or holders for immersion tests.

(3) Watch glasses, sealing films for spot tests.

(4) Mechanical rubbing device with test media for wipe tests.

(5) Temperature control unit (bath or chamber).

(6) Timer for exposure duration control.

(7) Optional: gloss meter, colorimeter, hardness tester.

Test Procedures

(1) Prepare the test specimens according to required dimensions and standards.

(2) Select the test method: immersion, spot, or wipe.

(3) For immersion: place specimens in ethanol-filled containers using racks.

(4) For spot test: place a defined amount of ethanol on the specimen surface and cover it.

(5) For wipe test: attach specimen and rubbing media to the mechanical device, set force, speed, and stroke number.

(6) Set the exposure temperature and duration using the control system.

(7) After completion, remove specimens, clean if necessary, and evaluate changes in visual appearance, weight, dimensions, or mechanical properties.

(8) Record observations or quantitative measurements for analysis.

Maintenance Information

(1) Clean test containers, chambers, and accessories after each test to avoid contamination or chemical residue.

(2) Inspect mechanical rubbing devices regularly for wear and maintain lubrication if required.

(3) Store ethanol and chemicals safely according to laboratory safety guidelines.

(4) Ensure temperature control units are functioning and calibrated.

(5) Periodically calibrate optional measurement instruments (gloss meter, colorimeter, hardness tester).

(6) Handle specimens and accessories carefully to avoid damage.
