ASTM F2546-06

Standard Test Method for Snowboard Step-in Bindings

SCOPE
1.1 This test method specifies the essential requirements for a snowboard step-in binding-boot system (see ); hereafter referred to as step-in snowboard bindings.
1.2 This test method is applicable to step-in snowboard bindings for adults and children. This type of binding system utilizes a mechanical interlocking mechanism, and the interlock mechanism of the system will be specific to the particular manufacturer. Compatibility between different systems is not expected or anticipated thus each potential combination of boot and binding requires testing.
1.3 For snowboard boots interfacing with ski binding, see ISO 11634.
1.4 For snowboard plate bindings, see ISO 14790.
1.5 For snowboard strap bindings made for soft boots, see ISO 14573.
1.6 For snowboard step-in bindings, see ISO 15344.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

coordinates is agreed to be in the center of the ankle joint
which is located approximately 100 mm from the plantar
surface and 80 mm from the back of the heel.

5. Apparatus
5.1 One artificial leg with fixed ankle joint of 80° without
toe section (see Fig. 2). Test size appropriate to the mid range
of the sizing for the boot-binding system being tested.
5.2 Arigid plate (for example, steel plate of at least 10–mm
thickness) with the appropriate mounting hole pattern for
mounting the binding capable of supporting the applied loads
and moments.
5.3 Test device capable of applying the described forces and
moments. The test device shall be designed to allow applica-
tion of a torque (see Table 1) with a force applied at the upper
