Full title and description

STB BS ISO 1126-2015 — Rubber compounding ingredients — Carbon black — Determination of loss on heating. This entry corresponds to the International Standard ISO 1126:2015 (adopted and published in national catalogues as BS ISO 1126:2015); it specifies standard test procedures for determining the loss on heating (primarily moisture and other volatiles) of carbon black used in rubber compounding.

Abstract

ISO 1126:2015 defines three laboratory methods to measure loss on heating of carbon black: method 1 (gravity‑convection oven — preferred), method 2 (moisture balance), and method 3 (infrared irradiation — rapid). The procedures, apparatus requirements, expressions of results and precision information are given; the methods do not apply to treated carbon blacks that contain added volatile materials.

General information

• Publisher: International Organization for Standardization (ISO); adopted/published in national catalogues as BS ISO 1126:2015 (British Standards Institution).
• ICS / categories: 83.040.20 (Rubber compounding ingredients).
• Edition / version: Edition 5 (2015).
• Number of pages: 7 (ISO PDF edition).

Scope

Specifies laboratory methods for determining the loss on heating of carbon black intended for the rubber industry. The measured loss is primarily due to moisture but may include traces of other volatiles. The standard applies to untreated carbon blacks; it excludes treated carbon blacks containing intentionally added volatile materials. Three alternative methods are provided to suit different laboratory equipment and throughput needs (gravity‑convection oven, moisture balance, and infrared rapid method).

Key topics and requirements

• Three specified test methods: method 1 (gravity‑convection oven — preferred), method 2 (moisture balance), method 3 (infrared irradiation rapid method).
• Oven temperature and control requirements (125 °C for method 1 and related tolerances), sample handling and desiccation procedures.
• Apparatus performance and measurement accuracy (balance sensitivity, oven uniformity, criteria for end point in rapid methods).
• Recommended sample sizes and procedural precautions to ensure repeatability and comparability of results.
• Instructions for calculation and expression of results, precision data and required content for the test report.

Typical use and users

Used by quality control and test laboratories in the rubber and elastomers industry, carbon black producers and suppliers, R&D departments working on rubber compounds, and conformity/inspection bodies. The standard supports product specification, incoming inspection of carbon black consignments, and comparative testing between suppliers.

Related standards

Standards referenced or related by subject include earlier editions of ISO 1126 (2006, 1992) and complementary methods for carbon black analysis such as ISO 21870 (determination of high‑temperature loss on heating by thermogravimetry); national adoptions (for example BS ISO 1126:2015) implement the ISO text for local use.

FAQ

Q: What is this standard?

A: ISO 1126:2015 (published/adopted as BS ISO 1126:2015) is an international laboratory test standard that specifies methods for determining the loss on heating of carbon black used in rubber compounding.

Q: What does it cover?

A: It covers three test procedures (gravity‑convection oven, moisture balance, infrared rapid method), apparatus and measurement accuracy requirements, sample handling, calculation and reporting of results, and precision information. It excludes treated carbon blacks containing added volatile materials.

Q: Who typically uses it?

A: Quality control and analytical laboratories in the rubber industry, carbon black manufacturers and suppliers, R&D teams, and inspection/conformity bodies use the standard to verify moisture and volatile content of carbon black.

Q: Is it current or superseded?

A: ISO 1126:2015 is the current published edition (edition 5, published September 2015) that replaced earlier editions (for example the 2006 edition). The ISO catalogue shows the 2015 edition as published/confirmed. National editions (for example BS ISO 1126:2015) represent the same text adopted for local use.

Q: Is it part of a series?

A: It is part of the family of standards and test methods for carbon black and rubber compounding ingredients — related documents include other ISO and BS methods dealing with different aspects of carbon black characterization (for example ISO 21870 for high‑temperature loss by thermogravimetry).

Q: What are the key keywords?

A: Key keywords are: carbon black, loss on heating, moisture determination, gravimetric oven method, moisture balance, infrared method, rubber compounding ingredients, ISO 1126.
