The assessment of snap attachment strength is an important criterion especially in the design and manufacturer of garments of infants’ and children wear. The measurement of an uniform force applied to the snap attachment shall be recorded by means of a force-measuring device (in this case a Calibrated Qinsun Push/Pull Scale is utilized) known as Snap Button Pullout Tester.

1. The assessment of snap attachment strength is an important criterion
especially in the design and manufacturer of garments of infants’ and children
wear. The measurement of an uniform force applied to the snap attachment
shall be recorded by means of a force-measuring device (in this case a
Calibrated Qinsun Push/Pull Scale is utilized) known as Snap Button Pullout
Tester. Once the appropriate force is registered on the Qinsun’s Button pull
test machine, a stop clock is used for recording a set period of time.
To define the garments manufacturer responsibilities and duties to ensure that
snaps are applied appropriately to all garments. Qinsun’s Button Pullout Tester
is used to perform button pullout test to prevent separation between the snap
and the garment, which represents a dangerous situation if the loose snap is
swallowed .
This test method cover an uniform force required to pull a snap attachment
perpendicular to the garment. The snap attachment is not forced to separate
from the garment. This method is required attachment of snaps to specimens
using specifications provided by the producers of the snaps. This test method
is used to establish correlation to wear conditions and for comparing different
brands and types of snap fasteners.
Snap Tester
Testing Standards:
ASTM D7142-2/F963, CFR 1500, EN 71 PART 1, GB 6675, ISO 8124, M&S
P115A
Applications:
Snap Tester is used to determine the holding or breaking strength of prong-ring
attached snap fasteners onto garments.
Product Information:
The Snap Tester consists of an Upper Snap Clamp, a Lower Fabric Clamp &
Force Gauge mounted on a stand. The snap component is gripped by the
Upper Snap Clamp and the garment is fixed to the lower Fabric Clamp. By
turning the Top Flywheel, the operator can apply a specific force and the

2. holding force or the breaking strength can be recorded. Capability can be
enhanced with clamps & accessories for testing of other Snaps, Jean Buttons,
Four Hole Buttons & Garments Accessories such as Zippers, Bows, Appliqué,
Toggles, Hooks/Bars, and D-Rings, among others.
