The OECD Guidelines for the Testing of Chemicals is a collection of about 150 of the most relevant internationally agreed testing methods used by government, industry and independent laboratories to identify and characterise potential hazards of chemicals. Every year new and updated Test Guidelines are adopted to meet the regulatory needs in OECD member countries. The most recent Test Guidelines were adopted in July 2016.
New deadlines for comments: Draft updated TG 492 on RhCE for eye hazard potential and draft updated performance standards for the validation of similar methods. The deadline for public comments of 3 October 2016.

This new Advisory Document replaces the 1995 consensus document on the Application of the Principles of GLP to Computerised Systems. It retains all of the key text from the original 1995 document, but includes new text to reflect the current state-of-the art in this field.

The objective of the present Guidance Document (GD) is to establish an Integrated 2 Approach to Testing and Assessment (IATA) for hazard identification of serious eye 3 damage and eye irritation potential of test chemicals (or the absence thereof) that 4 provides adequate information for classification and labelling according to the United 5 Nations Globally Harmonised System (UN GHS, 2015).
This work describes the various endeavours of OECD countries to develop harmonised methodologies for birds toxicity testing, including the successful outcomes or the reasons for stopping activities in some cases. The work has required commitment from countries and industry in terms of staffing and laboratory resources to perform experimental testing and generate data.
A new report has been launched by the OECD Ad Hoc Group on Substitution of Harmful Chemicals. The report identifies where gaps remain in terms of possible missing tools, guidance and research to support stakeholders engaged in alternatives assessment and substitution of harmful chemicals.

This Test Guideline describes procedures designed to estimate the acute oral toxicity of substances to birds, and it provides three testing options: (1) limit dose test, (2) LD50-slope test, and (3) LD50-only test.

This Test Guideline is designed for assessing the effects of chemicals on the reproductive output of the collembolans in soil. It is based on existing procedures (1) (2). The parthenogenetic Folsomia candida and sexually reproducing Folsomia fimetaria are two of the most accessible species of Collembola, and they are culturable and commercially available.
