Changes in ASTM Standards

reference standards can - and do - change without notice

keep up to date with Jim Hojnacki's monthly column, ASTM Standards That are Modified

In a typical construction project, there may well be thousands of individual components that must be specified. CSI recognizes several methods of specifying: descriptive, performance, reference standard, and proprietary. Use of reference standards is quite common, but often carelessly done.

The problem is that specifiers are too often unfamiliar with the reference standards they use. Proprietary specifications can be very simple, and it is easy to grasp the intent of descriptive and performance specs. But most specifiers don't take the time to read and understand their reference standards.

The result is conflicting requirements, incomplete specifications, and sometimes completely erroneous references. One amusing error I found while reviewing a specification was a requirement that topsoil meet a particular MnDOT standard. When I looked up the standard, I found that it was a specification for hot-dip galvanizing. I doubt if the sod grew very well, but the topsoil should last a long time.

Jack Lindeman recently compiled a list of standards, including ASTM, AAMA, AASHTO, ANSI, AWI, FGMA, MnDOT, NFPA, SDI, SSPC, UL, and several other sources. Printed single spaced in three columns, it is almost five pages long.

Following are a few of the ASTM standards that were changed in 1996. Jack's challenge to our industry members: Look up those standards that apply to your products and tell us what has changed. Responses will be published in specifics.
