D1230-22 – Standard Test Method Technical Guide
📐 Scope and Application
This test method covers the evaluation of the flammability of textile fabrics as they reach the consumer for apparel. It employs a 26-gauge hypodermic needle as the ignition source to classify apparel textiles and identify those with burning characteristics unsuitable for clothing.
The standard is applicable for specific categories of tight fitting children’s sleepwear under 16 CFR 1615 and 1616, but shall not be used for evaluating textiles in children’s sleepwear covered by Test Method D6545. It also excludes decorative fabrics and protective clothing such as those worn by fire service individuals.
⚙️ Test Apparatus and Procedure
The test uses a 26-gauge hypodermic needle as the ignition source to measure the response of materials under controlled conditions. The procedure involves exposing fabric samples to the ignition source and observing their burning behavior for classification.
Fire testing is inherently hazardous, so adequate safeguards for personnel and property must be employed. The values stated in SI units are to be regarded as standard. It is the responsibility of the user to establish appropriate safety and regulatory compliance.
📊 Key Measured Properties
The test method sets forth a classification system for apparel textiles based on their burning characteristics. It identifies textiles that are unsuitable for use in clothing. The response of materials to heat and flame is measured under controlled conditions, but this test does not incorporate all factors for fire hazard assessment.
