Kindly Sort this Query of Type 2 coupler

Ques. What should be the actual value to define a rebar coupler’s type i.e. whether type 1 or type 2?

As mechanical splicing is now days a very common procedure to avoid congestion in reinforcement and and even being allowed by standards like an example ACI 12.14.3 says — Mechanical and welded splices

12.14.3.1 — Mechanical and welded splices shall be

permitted.

12.14.3.2 — A full mechanical splice shall develop in

tension or compression, as required, at least 1.25fy of

the bar.

21.1.6 — Mechanical splices in special moment

frames and special structural walls

21.1.6.1 — Mechanical splices shall be classified as

either Type 1 or Type 2 mechanical splices, as follows:

(a) Type 1 mechanical splices shall conform to

12.14.3.2;

(b) Type 2 mechanical splices shall conform to

12.14.3.2 and shall develop the specified tensile

strength of the spliced bar

That means for the Application of couplers categories as Type 1 and Type for different grades of bars should have their testing values in accordance with like this:_

Grade Of Rebar	Fy of rebar	For Type 1 ,UTS VALUE(Min)	For Type 2? Which Min Value we consider?
415	415	415 * 1.25 = 518.75	Type 1 +What value ?
450	450	450*1.25 = 562.5	Type 1 +What value ?
500	500	500*1.25 =625	Type 1 +What value ?
550	550	550*1.25=687.5	Type 1 +What value ?

My query is what should be the minimum value to know which coupler is a type 2 coupler according to standard? Kindly Help!!!
