AI Overview

ASTM F963 Yo-Yo Ball Test Equipment, such as the GESTER GT-MB19B and similar models from Labtesting, measures the safety of elastic tethered yo-yo balls. It tests for neck strangulation hazards by measuring initial length and elongation under load, ensuring compliance with ASTM F963 Sections 4.37 and 8.24, usually at a 80rpm rotation speed.

Key Features and Test Method (per ASTM F963/GESTER)

Purpose: Measures the length and elastic constant of the yo-yo ball to prevent neck injuries.
Measurement: Tests initial length and length under strain using 0.1kg and 0.2kg masses, with specific clamping methods.
Standards: Adheres to ASTM F963-16/17 and other relevant international standards (e.g., ISO 8124-1, EN 71-1).
Equipment Components: Usually consists of a steel ruler, clamping fixtures, measuring scale, and weights.
Operation: Some advanced versions (like GT-MB19B) utilize a rotary motor to test the cord under 80 RPM while calculating the stretch.
Safety Requirements: Evaluates if the elastic cord, when fully extended, presents a strangulation hazard (typically length should not exceed 1000mm).

Clamping: Attach a fixed clamping device to the tether, 15±5mm from the ball.
Initial Length: Apply a mass (including the clamp) of 0.1±0.005kg, and measure the distance (
$cap L sub 1$
) between the two clamps.
Extended Length: Remove the weight, allow it to relax, then apply a 0.2±0.005kg mass and measure the new distance (
$cap L sub 2$
).
Verification: Check if the stretched length and material properties meet standard safety requirements.
