ASTM A888 Properties (Chem., Mech. & Rankings) 2022

In this post I'll talk about and give details about ASTM A888. First let's describe it and then have a look at its material's properties.

What is ASTM A888?

ASTM A888 is a Specification for Hubless Cast Iron Soil Pipe and Fittings for Sanitary and Storm Drain, Waste, and Vent Piping Applications

Category

Pipe and Fittings

Scope

This specification covers hubless cast iron soil pipe and fittings for use in gravity flow applications. It establishes standards covering material, manufacture, mechanical and chemical properties, dimensions, coating, test methods, inspection, certification and product marking for hubless cast iron soil pipe and fittings. These pipe and fittings are intended for non-pressure applications, as the selection of the proper size for sanitary drain, waste, vent, and storm drain systems allows free air space for gravity drainage.

Ok let's start with ASTM A888 chemical composition.

Chemical Composition

The castings shall be made of cast iron, produced by an established commercial method that provides adequate control over chemical and mechanical properties.

Learn more about chemical composition.

Now it's the mechanical properties turn:

Tensile Strength

21 ksi (145 MPa) min.

Learn more about what is tensile strength.

Allowable Stress

Depends on the project (And its factor of safety).

Learn more about the what is allowable stress.

My Material's Rank

While engineers will often look for the cheapest material they can use, I took a different approach to material's selection to help newbie students.

I ranked materials according to their yield strengths and ASTM A888 currently ranks 171 in my yield strength index. This means there are other 170 materials that are more resistant.

Note: I've analysed 134 materials in order to create an yield strength index. Check my astm material's comparison post for more details.

References

Citation

When you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information.

That gives credibility to your paper and it is sometimes required in higher education.

To make your life (and citation) easier just copy & paste the information below into your assignment or essay:

Luz, Gelson. ASTM A888 Properties (Chem., Mech. & Rankings). Materials Blog. Gelsonluz.com. dd mmmm. yyyy. <URL>

Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. Also replace URL for the actual url of this page (The < and > stay, ok?). This citation format is based on MLA.
