Direct Answer: The Random Tumble Pilling Tester evaluates resistance to pilling in fabrics and textiles by producing a controlled random rubbing motion at constant speed, per ASTM D-3512 and GM-96532-P.

What is the Random Tumble Pilling Tester?

The DSI‑55RTP Random Tumble Pilling Tester is used to measure the resistance of textiles, fabrics, and upholstery to pilling—the formation of tangled fiber balls on material surfaces caused by wear.

Which standards does it support?

• ASTM D-3512: Random Tumble Pilling Test Method
• GM-96532-P: Automotive materials specification

How does it work?

The apparatus generates a random rubbing motion at a precise, constant speed, following the test standards. The cycle duration is easily adjusted at the control panel. Samples are tumbled under controlled conditions to simulate wear and generate pilling.

Applications

Materials tested include clothing, textiles, upholstery, automotive seat belts, automotive seat covers, fabrics for railroad passenger cars, and materials for marine and airline industries.

Key features

• Consistent random rubbing motion per ASTM and GM methods
• Adjustable test cycle duration via control panel
• Designed for versatility across diverse textile and upholstery materials
• Durable, precision-machined build by DEK‑TRON instrument makers

Model and specifications

• Model: DSI‑55RTP (D/CS‑53 older models)
• Approx. size (W × H × D): 24 × 20 × 15 in.
• Approx. weight: 120 lbs
• Electricals: 115 V, 60 Hz, 1 phase (other options available)

FAQs

What is a pill?
A pill is a ball of tangled fibers that forms on fabric surfaces after wear, typically held to the surface by remaining fibers.

What types of materials can be tested?
Clothing textiles, upholstery, seat belts, seat cover materials, and fabrics used in automotive, railroad, marine, and airline industries.

How is test duration controlled?
Via the instrument’s control panel, which allows easy adjustment of cycle duration.
