Description (English):

Specifies procedures for the sampling of carbon black for use in the rubber industry, delivered in bulk, semi-bulk or packages.

SKU: ISO 1124:1988

Abstract

Overview

ISO 1124:1988 (Third edition) specifies standardized procedures for sampling carbon black used as a rubber compounding ingredient. Intended for the rubber industry, the standard covers sampling from bulk, semi-bulk and package deliveries and defines apparatus, minimal sample sizes, handling and reporting to ensure representative, traceable samples for quality assessment.

Key Topics

Scope and definitions
- Bulk: containers holding not less than 2 000 kg.
- Semi-bulk: containers holding more than 50 kg and less than 2 000 kg.
- Packages: containers of 50 kg or less.
Required apparatus
- Sample Splitter: single-stage riffle-type splitter for reducing portions without bias.
- Sampling device for packages: open tube with a seal lip, diameter not less than 25 mm, to reach the package geometric centre.
- Scoop: designed to minimize pellet breakdown when removing sample material.
- Airtight containers: minimum capacity 3 dm3 for storage of retained samples.
Sampling quantities and procedure highlights
- For bulk compartments: discard at least 5 dm3 from each sampling port, then take at least 1 kg or 3 dm3 from each port and place in an airtight container.
- If no sampling ports are fitted, take 1 kg or 3 dm3 from loading ports approximately 30 mm below the surface to avoid contamination.
- For packages: insert the sampling tube to the geometric centre, discard about 0.5 dm3, then take at least 1 kg or 3 dm3; alternatively use the scoop after removing the top 30 mm of surface material.
- When preparing laboratory test samples, pass individual samples through the riffle-type splitter at least twice; composite samples should be passed at least three times to reduce stratification.
Handling and storage
- Handle sample portions carefully to prevent pellet breakdown.
- Store samples in airtight containers until testing; retain individual or composite portions as required.

Applications

Establishing representative test samples for incoming carbon black shipments.
Supporting quality control and material acceptance procedures in rubber compounding and manufacturing.
Providing traceable, auditable sampling records for supplier verification and dispute resolution.

Related Standards

This document was prepared by ISO/TC 45 (Rubber and rubber products) and is the third edition, replacing the second edition (ISO 1124:1983).
When implementing ISO 1124:1988, consider cross-referencing other ISO standards on material sampling and laboratory testing procedures relevant to carbon black or rubber ingredient analysis.

Practical value: ISO 1124:1988 provides clear, repeatable sampling steps and reporting requirements so laboratories and quality teams can obtain representative samples, reduce variability from poor sampling, and maintain traceable records for shipment acceptance.
