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!!!

India, our country full of every sort of resources which can be gifted to any country by god touch wood we have all……we are a developing nation with having Excellency in many fields and along with a strong defense system, talent hidden in every part of the 35 provinces. youth is arising everything is going good with some problems but what’s new in this problems are all across the globe, but apart from solving these issues some our politicians or a term use “netaji” are diverting our route. Who gave them the right to diversify the country on the basis or language and caste.Raj Thackeray who calls him as a netas of Marathi, can he tells on which resource the Marathi’s are not given their rights? They are completely equal to any other Indian belonging to meghalaya, mizoram,u.p and Bihar. I am shocked that they call them selves “neta”.”Neta” was a term which was used for netaji subash Chandra Bose they were neta with their complete goals and perspectives in mind they knew in which directions they were guiding the nation.
Shaeed e azam Bhagat Singh a son of our country who in 1930’s also was completely aware of every thing happening in the world, such a great thinker they knew and understand their responsbilites, Gentleman I would like to appeal to all the youth of our country that “lets take a pledge in ourselves that what ever we do whatever decision we take,what ever step we take whether even it is of our studies think in this way how this step of our is going to effect my beloved nation.
