What is ISO 1920?

ISO 1920 is a multipart standard titled:

"Testing of concrete"

It includes various parts that specify test methods for concrete properties, including:

  1. Sampling fresh concrete
  2. Determination of compressive strength
  3. Flexural strength testing
  4. Water content, density, and air content measurements
  5. Testing hardened concrete properties such as permeability, shrinkage, and durability

This comprehensive suite of test methods enables accurate assessment of concrete quality, which directly affects the safety and performance of buildings, bridges, roads, and other infrastructure.

Why is ISO 1920 important?

Concrete quality is paramount in construction safety and longevity. Without standardized testing methods:

  1. Structural failures and defects may occur
  2. Projects may face delays due to quality issues
  3. Material wastage and cost overruns can increase
  4. Compliance with local and international building codes is compromised

ISO 1920 standardizes testing procedures to ensure consistent, reliable, and repeatable evaluation of concrete, helping stakeholders make informed decisions.

What are the benefits of ISO 1920?
