how purolater tests filters (flow rates)

purolater wrote me this:
PureOne filters meet the flow requirements of automotive applications. We
test our filters per SAE specification HS806 Chapter 1, and the standard
flow rate requirement that we follow states that the pressure differential
(between inlet and outlet) shall not exceed 3.0 psi at a flow rate of 3.0
gpm. On the PL30001 filters, flow restriction is 0.8 psi (avg) at 3.0 gpm.

My question is why don't all the people testing oil filters use these SAE specs?????????
Instead of testing at whatever flow rate and temperature theylike??????????

The cynic in me tells me the answer is simple. If they all did standard testing and publicized it it would allow the consumer to directly compare filters and cause the sales of a lot of expensive and over-hyped filters to drop to nothing...

what about all the "home" tests we see.
seems they would try to use the SAE standards of flow and temperature
