Impact-attenuating surfaces, like this one installed
by TotTurf at a Portland,
Oregon, park, can include
multiple types of materials.

task group ever had a chance to review that information, a letter ballot
was distributed to the full subcommittee, which then voted to approve the
changes to the standard.
By way of background, the standard for surfaces installed under and
around playground equipment is
based primarily on two factors: Head
Injury Criterion (HIC), which is a
score for the measure of head injury
severity, and g-max, a gravity-based,
instrumented measurement that represents the maximum deceleration
experienced at the point of impact in
a fall, usually calculated in milliseconds. The recently approved change
to the existing ASTM standard reduces the HIC from 1000, the level it
has been since 1991, to 700. A lower
HIC number and lower g-max value
indicates better performance by surfaces in absorbing impact.
The implications of this new standard, F1292-14, if formally adopted,
will be highly significant for public
parks and recreation because the
higher standard for impact attenuation may require the surfaces of
many playgrounds to be replaced or
upgraded, or the playgrounds to be
taken out of service.
	

Although ASTM standards for
playground surfacing materials do
not constitute law or regulation in
and of themselves, they may be codified within state regulations that require local adherence to the ASTM
standard. No matter whether they
are adopted as regulation or not, the
ASTM standard for playground surfacing is influential in determining
contract specifications by park and
recreation agencies when deciding
how shock absorbing they want their
installed playground surfaces to be.
The HIC score is one of the determining factors in making that decision. Agencies that contract out the
installation of playground surfaces
decide what HIC rating they want
their playgrounds to meet, and then
installers generally provide proof that
their surfacing system has been tested
in a lab or in the field to determine
that it meets the specifications set
forth in the contract.
The Consumer Product Safety
Commission (CPSC) first issued
guidelines in 1981 and has updated
them regularly in the Handbook for
Public Playground Safety (www.cpsc.
gov/pagefiles/122149/325.pdf).
