API 5L, Standard specifies requirements for the manufacture of two product specification levels (PSL 1 and PSL 2) of seamless and welded steel pipes for use in pipeline transportation systems in the Petroleum and natural gas industries.
Level PSL 1 provides a standard quality level for line pipe.
Level PSL 2 has additional mandatory requirements for chemical composition, notch toughness and strength properties and additional NDE.
Requirements that apply to only PSL 1 or to only PSL 2 are so designated.
Requirements that are not designated to a specific PSL designation apply to both PSL 1 and PSL 2.
The pipe grade for PSL 1 pipe is identical to the steel grade (designated by a steel name). It consists of an alpha or alphanumeric designation that identifies the strength level of the pipe and is linked to the chemical composition of the steel
The pipe grade for PSL 2 pipe shall be as given in Table 1 and consists of an alpha or alphanumeric designation that identifies the strength level of the pipe. The steel name (designating a steel grade), linked to
the chemical composition of the steel, additionally includes a suffix that consists of a single letter (R, N, Q or M) that identifies the delivery condition

The different in the psl1 that the requirement is only minimum for all the specifications like tensile strength and yield strength and the percentage of element in the product like carbon , magnesium and sulfur.... but in the PAL2 the requirement is a minimum and maximum.

Dear All
Can you tell the difference between PSL 1 and PSL 2 specification levels as per API 5L.
Thanks and Regards
