The new restrictions were introduced in the months following the launch of the iPhone 6 and 6 Plus and will require case makers to protect Apple devices from drops up to a 1 meter (3.2 feet) onto a hard surface like pavement. That includes protection of the device in any orientation including the usually exposed cover glass on the Apple device.
In addition to this, cases now must also protect the display of the iPhone, iPad, or iPod when lying flat on a surface. Cases have to provide a buffer of at least 1mm between the cover glass and the flat surface. Manufacturers can either cover the glass entirely or have their case protrude slightly from the glass to keep it from touching the surface.
Finally, Apple is restricting manufacturers from using a number of substances/materials including Formaldehyde, Endangered species of flora and fauna, PFOS, PFOA, PBDE, PBB, and Phthalates. Some of the restrictions are due to new environmental regulations and others such as Phthalates are being banned following studies that show adverse health effects.
