ASTM D8618

ASTM D8618 is the ASTM standard for determining the degree of disintegration of items under defined in-field composting conditions using article dosing. It provides a structured way to evaluate how a product behaves in a composting environment, helping manufacturers, buyers, and testing teams compare performance with greater consistency. As a technical document, it supports more reliable product assessment where compostability-related claims and field-relevant testing conditions matter.

What is ASTM D8618?

ASTM D8618, titled Standard Test Method for Determination of the Degree of Disintegration of Items Under Defined In-Field Composting Conditions Using Article Dosing, describes a test approach focused on disintegration rather than broad environmental claims. The standard is intended to measure how items break down when exposed to defined composting conditions in the field. It is especially useful when a consistent method is needed to evaluate physical breakdown and compare results across products, materials, or test programs.

Where is ASTM D8618 used?

This standard is commonly used in product development, certification support, and quality control workflows involving items intended for composting environments. It may be applied when evaluating articles made from compostable or compost-related materials, especially where field conditions are part of the performance question. Laboratories, material suppliers, and procurement teams can use ASTM D8618 to support testing programs that rely on defined composting exposure and repeatable article dosing procedures.

Why is ASTM D8618 important?

ASTM D8618 helps bring consistency to a test area that can otherwise be difficult to compare across products and sites. By defining how disintegration is assessed under in-field composting conditions, it supports more credible test results, better procurement decisions, and clearer compliance documentation. For organizations evaluating composting-related performance, the standard can reduce uncertainty and help align testing practices with a recognized ASTM method. ASTM D8618 is therefore useful for both product evaluation and risk reduction.
