Paints, varnishes and binders - Determination of MEQ value of water-based coating materials and binders (ISO 15880:2000)

Specification of a titrimetric method for determining the MEQ (milli-equivalent) value of water-based binders and coating materials, either as MEQ(acid) value or an MEQ(alkali) value.

Peintures, vernis et liants - Détermination de la valeur MEQ des produits de peinture et liants à base d'eau (ISO 15880:2000)

L'ISO 15880:2000 spécifie une méthode titrimétrique de détermination de la valeur MEQ (milli-équivalent) des liants et produits de peinture à base d'eau, en valeur MEQ(acide) ou en valeur MEQ(alcaline).
Contrairement aux autres valeurs, par exemple l'indice d'acidité, la valeur de saponification ou l'indice hydroxyle, la valeur MEQ est toujours liée à l'extrait sec du liant ou du produit de peinture.

Overview

EN ISO 15880:2004 is a European and international standard specifying a reliable titrimetric method for determining the MEQ (milli-equivalent) value of water-based paints, varnishes, and binders. Developed by ISO Technical Committee ISO/TC 35 and adopted by CEN, it defines how to measure the acid or alkali MEQ value relative to the non-volatile matter content in coating materials and binders. The standard is crucial for quality control and formulation of water-based coatings, ensuring consistent chemical properties and performance.

Key Topics

  • Scope and Purpose
    The standard applies specifically to water-based coating materials and binders. It measures the acid or alkali MEQ value, unlike other values such as acid value or hydroxyl value, which are not normalized to non-volatile content.

  • Titrimetric Determination Method
    Utilizes volumetric titration with standard solutions of potassium hydroxide, hydrochloric acid, or perchloric acid depending on whether the MEQ value of acid or alkali is being tested. The method includes sample dissolution, titration using potentiometric apparatus, and titration curve analysis.

  • Sample Preparation and Testing

    • Representative sampling according to ISO 15528
    • Determination of non-volatile matter content as per ISO 3251
    • Use of suitable solvents (e.g., methoxypropanol) and possibly emulsifiers for sample dissolution
    • Duplicate determinations to ensure precision
  • Precision and Accuracy

    • Repeatability limits of 5% for MEQ(acid) and 3% for MEQ(alkali) reflect within-laboratory consistency
    • Reproducibility limits of 8% (acid) and 6% (alkali) ensure reliable inter-laboratory results
  • Reporting Requirements
    Includes reference to ISO 15880, product identification, test results, deviations, and test date. Results are reported as mean values with appropriate significant figures.

Applications

  • Quality Control in Paint and Coating Manufacturing
    Ensures correct acid/base balance in water-based binders and coatings, critical for product stability, drying times, and surface adherence.

  • Formulation and R&D
    Assists formulation chemists in adjusting binder acidity or alkalinity to optimize coating performance and durability.

  • Regulatory and Compliance Testing
    Facilitates compliance with industry standards by providing standardized, reproducible chemical measurements.

  • Supplier and Batch Verification
    Enables verification of raw material consistency and batch-to-batch reproducibility for water-based coating components.

Related Standards

  • ISO 3251: Specifies determination of non-volatile matter content in paints and varnishes, which is essential to normalize MEQ values.
  • ISO 15528: Defines sampling procedures for paints, varnishes, and raw materials to obtain representative test samples.
  • Other paint and binder standards from ISO/TC 35 providing complementary methods and specifications for coatings quality assessment.
