ASTM E10, “Standard Test Method for Brinell Hardness of Metallic Materials,” has been updated yet again! The new 2015a Edition is available from Document Center Inc. now in both paper format and for pdf download. And as I have mentioned before, ASTM standards that are updated frequently are perfect candidates for our multi-user Standards Online subscription service, since updates are posted to your account immediately with no additional charge.
Of course, I’ve described how the standard provides you with everything you need to know in order to conduct tests to determine the brinell hardness of various metallic materials in previous posts. So it’s likely that you already use this standard in your operations.
I’m sure that you’re now interested in finding out what the changes are in the 2015a Edition that’s just been released. But first, since I last reviewed the standard when the 2014 Edition came out, there’s a missing review of the 2015 Edition that has been in effect since July. So let’s take a look at those changes first, and then we’ll review the 2015a changes after that.
In July, ASTM E10 had changes made to the Annex A. These can be found is section A220.127.116.11, which covers how many hardness tests you need to make for the daily verification test blocks.
The new 2015a revision (approved by the committee at the beginning of December) is also a technical revision, this time updating the calculation found in section 3.2.4, for determining the error E in the performance of a Brinell hardness machine. Additionally, the section on tests for flat surfaces (7.6.3) has been modified. The ambient temperature section has been updated (7.8). And Table 5’s values have been completely redone (for the summary of statistical information).
This is indeed a change to the 32-page standard that you’ll want to review, so you’ll want to purchase your copy asap. Go directly to the Document Center webstore to purchase an authorized copy. It’s at www.document-center.com. And here’s the direct link to the order page for ASTM E10!
And if you want to make sure that you’re able to identify all the changes, contact our staff and ask for the redline edition of this standard. You’ll receive two copies, one with the mark-up provided by the committee and the other clean copy of the new edition. Just check in with our staff for more information — you can reach them by phone (650-591-7600) or email (email@example.com). We’ve been selling authorized copies of the ASTM standards since the 1980’s. Make us your Standards Experts!
