Full title and description

ISO 3386-1:1986/Amd 1:2010 — Polymeric materials, cellular flexible — Determination of stress‑strain characteristics in compression — Part 1: Low‑density materials — Amendment 1. This document is an amendment to ISO 3386-1:1986 providing updates to the original compression stress‑strain test method for low‑density flexible cellular polymeric materials.

Abstract

The amendment modifies aspects of the test procedure for determining compression stress‑strain characteristics of low‑density flexible cellular polymeric materials (materials with density up to 250 kg/m³), clarifies calculation methods for compression stress values and updates specific test conditions and equipment requirements.

General information

• Status: Withdrawn / superseded.
• Publication date: April 2010 (Amendment 1 published 2010‑04).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 83.100 (Cellular materials).
• Edition / version: Amendment 1 to ISO 3386-1:1986 (Edition 2; Amd 1:2010).
• Number of pages: 1 (amendment document).

Scope

This amendment applies to ISO 3386-1:1986 (Part 1 — low‑density materials) and introduces targeted changes to the original test standard — chiefly clarifications and updates to test‑machine requirements, specimen conditioning and related procedural details for compression stress‑strain testing of low‑density flexible cellular polymeric materials (up to 250 kg/m³). The amendment itself is short (a one‑page amendment) and was later superseded when ISO 3386‑1 was fully revised.

Key topics and requirements

• Determination of compression stress‑strain characteristics for low‑density flexible cellular polymeric materials (up to 250 kg/m³).
• Clarifications/updates to test‑machine specifications (loading platen, alignment, loading rate and measurement accuracy).
• Requirements for specimen preparation and conditioning prior to testing.
• Formulas and calculation methods for reporting compression stress values and stress‑strain curves.
• Context: this amendment amends the 1986 edition and was later superseded by a full revision published as ISO 3386‑1:2025.

Typical use and users

Used by materials test laboratories, product manufacturers (foam and flexible cellular polymer producers), quality control personnel, research and development teams, and standards committees for ensuring consistent measurement of compression load‑bearing properties of low‑density cellular polymeric materials. The amendment was intended to harmonize machine and conditioning practices for more reproducible results.

Related standards

ISO 3386‑1:1986 (original standard amended by this document) and ISO 3386‑2 (high‑density materials); ISO 2439 (indentation hardness of flexible cellular materials) and ISO 1923 (dimensional measurement of cellular materials). The amendment and the 1986 edition were later incorporated into the revised ISO 3386‑1:2025.

FAQ

Q: What is this standard?

A: ISO 3386-1:1986/Amd 1:2010 is Amendment 1 (published April 2010) to ISO 3386‑1:1986, which provides targeted changes to the compression stress‑strain test method for low‑density flexible cellular polymeric materials.

Q: What does it cover?

A: It covers updates and clarifications to the method for determining compression stress‑strain characteristics (including machine and conditioning requirements and calculation methods) for low‑density flexible cellular polymeric materials (materials up to 250 kg/m³).

Q: Who typically uses it?

A: Testing laboratories, foam and flexible cellular material manufacturers, QA/QC and R&D teams, and standards developers who perform or rely on standardized compression testing for product specification and comparison.

Q: Is it current or superseded?

A: The amendment (and the 1986 base standard) has been withdrawn and superseded by a full revision — ISO 3386‑1:2025. The amendment itself was published in April 2010 and subsequently incorporated into later revisions.

Q: Is it part of a series?

A: Yes — ISO 3386 is a multi‑part series. Part 1 covers low‑density materials (this amendment), and Part 2 covers high‑density materials; related ISO standards (for hardness and dimensional measurement) are often used alongside ISO 3386.

Q: What are the key keywords?

A: Compression stress‑strain, flexible cellular polymeric materials, foam, low‑density, specimen conditioning, test machine, ISO 3386‑1, amendment.
