I just did a quick search and found that the B898-05 from 2005 replaced the previous B898-99 from 1999.

I did not see any other earlier historic standards, but I am not on that particular subcommittee. Often, subcommittee members have more access to other old records and work groups that create working documents and the ultimate standards.

It is very possible/probable that B898 was a part of a previous standard and was split off in the never-ending chore of keeping standards current and viable.

Perhaps someone on the committee responsible for B898 or ASTM itself could help you.

Before you order any documents, consider joining and getting on a committee of your interest (not always easy). As a member of ASTM for less than $100, you get a complete volume (comtaining several hundred similar standards) free (value over $150). You also get big discounts on other standards. It is a real bargain if you get involved in stanards for any discipline.

2nd paragraph of footnote 1 of B 898 says:

Quote:

Current edition approved May 1, 2005. Published June 2005. Originally approved in 1999. Last previous edition approved in 1999 as B 898 – 99.

The footnotes on the first page of each ASTM standard mention the publication dates of both the original and most recent previous editions.

Also, the free, on-line document summary for each standard has a link

ASTM B898 seems first published in July 1999 (I have hard copy & nothing earlier is mentioned): http://www.astm.org/cgi-bin/SoftCart.exe/DATABASE.CART/REDLINE_PAGES/B898.htm?L+mystore+tokx9492
 

Thanks all of you

As per B898

1.1 This specification covers plate consisting of a base metal to which is bonded, integrally and continuously, on one or both sides a layer of one of the following: titanium, zirconium, tantalum, niobium, and their alloys. The material generally is intended for   pressure vessel use.

Where as Pressure vessels are dealt by ASME.
ASME Sec II B does not list this under Section II B.

Does this mean we can still use this for Pressure vessels?
If no how can ASTM declare that the material is good for Pressure Vessels.

It is my understanding that it is ASME who decideds the use of ASTM material and if suitable for Pressure vessel adopts into ASME Sec II B.

Am i missing something???

The ASTM standard for a material gives the properties the material must have. It also gives the associated test procedures that are used to determine those properties.

It does not prescribe how the material must be used. The phase "The material generally is intended for pressure vessel use" is just informational regarding an inteded use, but does not say it is suitable for all pressure vessels.

There may be a number of ASTM materials standards that are also intended for pressure vessels depending on the properties needed. Specifying the material to be used is up to the designer and the ASTM material standard designation is how to signify which material should be used.

You look to see if there is an SB898, then you will know what the design guidelines are.
With some clad materials the core is tested and qualified to meet a particular spec, and the cladding is just along for the ride.

Remember that there are a lot of systems (piping, vessels, tanks) that are built that do not need to conform to the B&PV Code.  The Code usually addresses situations where public safety is a critical concern.

Often the difference between the ASTM spec and the version adopted by ASME is that certain testing is required by ASME.

And, JOIN ASTM.  You can vote by email and never attend a meeting, but it is a valuable experience, and you meet some great people at the meetings.
