What You Should Know about ASTM for Indoor Playground?
If you have the purchase plan for indoor playground, you'd better equipment yourself with some basic safety standard to help you avoid unprofessional manufacturer or sellers. The below are some basics for your quick understand, and hope they'd be a great help for you.
6.2.1 Accessible Openings - A completely bounced rigid opening is accessible when it is possible to insert the torso test probe into the opening to a depth of 4.0 in. (100mm) or more.
6.2.2 Nonrigid Completely Bounded Openings - A nonrigid opening such as may be found in but not limited to flexible torso probe will penetrate the opening to a depth of 4.0 in. (100mm) or more when tested in accordance with the test procedure outlined in 188.8.131.52 (See Figs. A1.1 and A1.2 for probe dimensions).
6.2.3 Angular Portions Openings - Angled formed by the surface of an opening (that is, adjacent surfaces or surfaces that intersect when projected with a distance between surfaces greater than 9.0 in. (230mm)) should be at least 55°unless one of the conditions defined in 184.108.40.206 exists.
· Flat open chutes should have slides at least 4 inches high extending along both
sides of the chute for the entire length of the inclined sliding surface.
· Slides may have an open chute with a circular, semicircular or curved cross section
A. The vertical height of the slide is no less than 4 inches when measured at right
angles to a horizontal line that is 8 inches long when the slide is intended for
Toddlers, 12 inches long when the slide is intended for preschool-age-children,
and 16 inches long when the slide intended for school-age-children; or
B. For any age group, the vertical height of the slides is no less than 4 inches
minus two times the width of the slide chute divided by the radius of the slide
Chute Exit Region
All slides should have an exit region to help children maintain their balance and facilitate a smooth transition from sitting to standing when exiting. The chute exit region should:
· Be between 0 and -4°as measured from a plane parallel to the ground.
· Have edges that are rounded or curved to prevent lacerations or other injuries
that could result from impact with a sharp or straight edge.
· For toddlers the chute exit region should:
- Be between 7 and 10 inches long if any portion of the chute exceeds a 24°
- Be no more than 6 inches above the protective surfacing.
- Have a transition from the sliding portion to the exit region with a radius of
curvature of at least 18 inches.
· For preschool and school-age the chute exit region should:
- Be at least 11 inches long.
- Be no more than 11 inches above the protective surfacing if the slide is no
greater than 4 feet high.
- Be at least 7 inches but no more than 15 inches above the protective surfacing
if the slide is 4 feet high.
