ASTM C-76 vs C-478

ASTM C-76 vs C-478

ASTM C-76 vs C-478

In a nutshell.......what's the difference?

I initially thought the C-76 was thicker but found that was not the case.  It is my understanding that C-76 is more robust due to more rebar but having a hard time verifying.  I may need to break down and buy the ASTM standards but wouldn't have much need for them beyond this question.

Any help would be appreciated.  Thanks.

RE: ASTM C-76 vs C-478

one is for storm drain pipe the other is for manholes

Designation: C76 – 11 Standard Specification for Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe

Designation: C478 – 11 Standard Specification for Precast Reinforced Concrete Manhole Sections

RE: ASTM C-76 vs C-478

Appreciate that.  That's the typical use but what about material differences?
