OECD 113 – Thermal Stability and Stability in Air

OECD 113 is a preliminary assessment to evaluate the stability of a substance with respect to heat and air.

OECD 113 is commonly used to determine stability and is used as guidance in the performance of other tests. The determination of storage stability is applicable to homogeneous solid and liquid substances and to mixtures of these.

OECD 113 is a preliminary assessment to evaluate the stability of a substance with respect to heat and air.Two principle test methods are performed:

  • Accelerated storage test: a 14 day storage test that applies higher temperatures to the test chamber during a short time period.

Accelerated storage testing determines the stability of a material over time.  OECD 113 and similar Shelf life and Accelerating aging tests are commonly performed for Personal Care Products, Pet Care Products, Fuels and Pesticides.

  • Thermal Analysis: samples are heated up to a final temperature in a defined test atmosphere; the weight change of the sample or quantities of heat absorbed or given off is measured and recoded.

Storage stability is a common requirement for many product registrations including US EPA Pesticide registration and re-registration.  The regulatory document 40 CFR Part 158, Data Requirements for Registration, outlines a variety of requirements for pesticide registration.  OECD 113 and EPA 830.6317 are common methods to determine the storage stability of a substance.  Furthermore, OECD 113 includes the Thermal Analysis in air component.

As of 2012, the EPA recommends performing the Accelerated Storage Stability and Corrosion Characteristics Study for pesticide re-registration. However, if the the requirements are not met for this 14 day test, a traditional 1-year study will be recommended. When testing for regulatory purposes, it is highly recommended to review testing requirements with the appropriate regulatory agency prior to testing.
