This MDS defines the applicable options and/or requirements that supplement or amend the
referenced standard specification.
For ASTM A106, as per referenced standards with the following additional requirements:
C < 0.23%
S < 0.020%
P < 0.025%
CE < 0.43%
Carbon equivalent (CE) = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15
For API 5L pipes, chemical composition shall be as per API 5L PSL-2 standard. Nevertheless, the
maximum carbon content shall be the lower between 0.23% and that specified in API 5L for the
delivered condition.
3. HEAT TREATMENT
General: Microalloying elements (Nb, V, Ti, B) shall not be deliberately added.
As per referenced standards with the following additional requirements:
4. MECHANICAL TESTS
For tempered piping, the minimum tempering temperature shall be 620 ºC (unless a higher
minimum temperature is required by the corresponding standard).
As per referenced standards
5. IMPACT TESTS
For ASTM A106- B/C: thickness above 12.7 mm shall be impact tested. Impact testing shall be
conducted in accordance with ASTM A370. Impact test temperature shall be -29 ºC. Full size
specimens (10 mm x 10 mm) shall be used. Acceptance criteria shall be:
Average of 3 specimens: min 20J
Minimum of 3 specimens: min 16J
For API 5L B: material shall be impact tested in accordance with API 5L PSL-2. For thickness above
12.7 mm, Impact test temperature shall be -29 ºC. The acceptance criteria shall be as below:

9. MARKING
The pipes shall be marked to ensure full traceability to melt and heat treatment lot.
10. CERTIFICATION
The material manufacturer shall have a quality system certified in accordance with ISO 9001 or
equivalent approved by Company.
The inspection documents shall be issued in accordance with EN 10204 Type 3.1 and shall confirm
compliance with this Specification.
11. ADDITIONAL
CERTIFICATION FOR
MARINE SYSTEMS
The inspection documents shall include the following information:
Heat treatment condition. For tempered condition, tempering temperatures shall be
stated.

As per Class Requirement (Class I, Class II, Class III, defined by Class) and EN 10204 Type
3.1, where Class Certification is applicable.

As per EN 10204 Type 3.1, where Class Certification is not applicable.
