ISO 1431-1是關于《塑膠、硫化橡膠或熱塑性橡膠耐臭氧龜裂》的測試方法，現行最近的標準為ISO 1431-1-2012，

ISO 1431標準范圍

ISO 1431這部分指定用于評估在靜態或動態拉伸條件下和溫度中，暴露于含有一定濃度的臭氧的空氣中抗硫化橡膠或熱塑性橡膠開裂時的程序，排除直接光照的影響。

主要注意的是由于不同的橡膠制品的耐臭氧性能在不同的環境下，會有比較為顯著的不同，例如臭氧濃度和溫度的影響。此外由于實際使用中的產品尺寸規格與測試中的樣品不一致，也可能造成測試結果與實際使用過程中出現形變的不一致。因此標準的是使用者需謹慎在測試結果與實際使用過程的相關性進行評估。

ISO 1431英文摘錄

WARNING — Persons using this part of ISO 1431 should be familiar with normal laboratory practice.This part of ISO 1431 does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and toensure compliance with any national regulatory conditions.

1 Scope

This part of ISO 1431 specifies procedures intended for use in estimating the resistance of vulcanized or thermoplastic rubbers to cracking when exposed, under static or dynamic tensile strain, to air containing a definite concentration of ozone and at a definite temperature in circumstances that exclude the effects of direct light.

Great caution is necessary in attempting to relate standard test results to service performance since the relative ozone resistance of different rubbers can vary markedly depending on the conditions, especially ozone concentration and temperature. In addition, tests are carried out on thin test pieces deformed in tension and the significance of attack for articles in service can be quite different owing to the effects of size and of the type and magnitude of the deformation. Explanatory notes on the nature of ozone cracking are given in Annex A.

Reference and alternative methods for determining the ozone concentration are described in ISO 1431-3.
