DB's Corner: ASTM

By Dennis Buirge

It would be surprising to find someone using construction documents who has not ‘heard’ of ASTM standards.  How many, though, have an introductory understanding regarding the meaning of those letters and numbers?  Specification writers in particular are familiar with those 4 letters, ASTM, as standards are frequently used when preparing a specification, especially in the ‘reference standard’ method.  The intent of this blog is to give an introduction to various meanings so that one could at least call themselves an introductory neophyte regarding an understanding of ASTM standards. 

If your specification Section incorporates a PART 1 Article entitled ‘References’ and includes “ASTM - American Society for Testing and Materials”, you are now about a decade behind the times.  With ASTM founded in 1898 as the American Section of the International Association for Testing and Materials, it predates other standards organizations such as BSI (1901), DIN (1917), ANSI (1918) and AFNOR (1926).  The organization's headquarters located in West Conshohocken, PA, is about 5 miles NW of Philadelphia.  ASTM currently includes members from more than 120 nations, and with about one of every five members living outside the United States and the standards being used around the world in many applications, a new name, ASTM International, Inc. was established in 2001.  In addition, a new logo was included to underscore their international scope and message.  There are now about 12,000 standards that can be searched for titles, scopes, adoptions, referenced documents, index terms, number of pages, and prices on the ASTM website. 

In a specification, one might see a standard reference of ASTM B 221, where there is at least a letter and up to a four digit number, but may also include a dash and a two digit number.  So what is the meaning of that designation in ASTM standards?  The first letter identifies a general designation, followed by its serial number, which is separated from the standard’s year designation by a dash.  The general designation legend is as follows:  A = Ferrous Metals, B = Nonferrous Metals, C = Cementitious, Ceramic, Concrete, and Masonry Materials, D = Miscellaneous Materials, E = Miscellaneous Subjects, F = Materials for Specific Applications, G = Corrosion, Deterioration, and Degradation of Materials, and H = Joint Committee and District Recipients.  One would then know that ASTM B 221 falls into the nonferrous metals category and happens to be extruded aluminum; B 209 identifies sheet aluminum.  The year need not be referenced in Divisions 02 - 49 specifications, if there is a statement in Division 01 that the most current standard at the time of bidding is valid. 

All ASTM standards fall into 15 sections with each section containing many volumes.  The example for construction relates to its falling in Section 4, where there are 13 volumes (4.01 - 4.13).   If one were interested in obtaining all 12,000 standards in all 82 volumes, get out your checkbook, as the 2010 edition is available for approximately $9,700 (verify actual amount with the ASTM website).  About 1,300 construction related standards in a 4 volume set are available, however their website indicates only electronic files are now available and no longer in book form.  The beginning of each construction related volume first includes an alphabetic listing of standards by “content” and then by “list of subjects”, which identifies each standard in one of the six different types explained in the next paragraph. 

The standards are uniform in format and follow the same rigorous approval procedures.  In general, there are six different types of ASTM standards: Test Method - a definitive procedure that produces a test result [Example - E 283-04 Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen]; Specification - an explicit set of requirements to be satisfied by a material, product, system, or service [Example - B 2-08 Standard Specification for Medium-Hard-Drawn Copper Wire]; Guide - information or series of options that does not recommend a specific course of action [Example - C 1193-09 Standard Guide for Use of Joint Sealants]; Practice - a definitive set of instructions for performing one or more specific operations that does not produce a test result [Example - A 807-08 Standard Practice for Installing Corrugated Steel Structural Plate Pipe for Sewers and Other Applications]; Classification - a systematic arrangement or division of materials, products, systems, or services into groups based on similar characteristics such as origin, composition, properties, or use [Example - D 448-08 Standard Classification for Sizes of Aggregates for Road and Bridge Construction]; and Terminology - a document comprising definitions of terms; explanations of symbols, abbreviations, or acronyms [Example - D 16-08 Standard Terminology for Paint, Related Coatings, Materials, and Applications]. 

In addition to all of the aforementioned information, there can still be up to 5 callouts with additional numbers and letters that could cause severe confusion.  One example for a classification type standard would be: ASTM D 4066-01 PA0610G33A49360UA067.  Have fun with that one!  Anyone seeking more detailed information regarding ASTM standards can ‘google’ various websites. 

Lastly, MasterSpec and other specification software generally incorporate ASTM standards that include references to both Imperial and SI (metric) units.  An example relating to guy and tie wires for planting stabilization in Section 329300 would be ASTM A 641/A 641M.  If the project manual is not specifying SI units for the project, the specification writer(s) SHOULD NOT include those SI references.  The previous example would be correctly written as ‘ASTM A 641’.  Removing those SI references could be physically deleted or ‘turned off’ via electronic software.

The NG-SEC Series Continues... Physical Security

By Lori Kleckner

This installment in the NG-SEC series discusses physical security guidelines. Although one may not think of physical security as a topic in a cyber security arena, without physical security, network devices are left unprotected from the surrounding environment. All NG9-1-1 information resources must be kept physically secured and protected from theft, misappropriation, misuse, unauthorized access and damage. NG-SEC section 8, Physical Security Guidelines includes:

• Building and Physical Access Control
• Authorized Physical Entry
• Storage Media and Output
• Mobile Devices
• Environmental Controls
• Server Room
• Data Communications Network

During PSAP assessments L.R. Kimball observes PSAPs are generally cognizant of physical security. Among positive findings are closed circuit cameras, keypad entry, attended reception area, and logging visitors. However, once access is gained to the facility, it is common to find the doors to the call center and equipment rooms left open and unattended.

A particular concern for physical security is third-party vendors with open access to the facility. While it is understood that there is a need for certain vendor employees to gain access to the facility on a 24 hour basis, it is not to say that their presence should be completely unattended. It is recommended that such personnel be logged in and their actions while in the facility monitored. It is important that the PSAP is aware of tasks that are performed by all personnel who have access to sensitive areas to prevent mishaps and to remain informed of actions taken.

Another point of concern during assessments is minimal concern afforded to areas with environmental controls. Physically securing the environmental controls is an important and often overlooked aspect of security. With server rooms and workstations that are reliant upon proper temperature and humidity control to operate, environmental controls are necessary. If equipment is not properly cooled, it will overheat resulting in system shutdown, data loss and possible equipment and software damage.

Similar areas of physical concern are:

• Commercial power rooms
• Emergency power rooms
• Communications rooms
• Cable vaults
• Switch rooms
• HVAC equipment rooms
• Operations control rooms

As PSAPs become connected via IP enabled networks, physical security is a growing responsibility that requires further attention. Unattended areas provide the opportunity for data theft and network interruptions. PSAPs should address physical security throughout the facility to assure restricted areas are available only to personnel with a business need.

Our next post will discuss network and remote access security.

Shale gas: Changing the oil and gas industry

In the modern classic ‘Zen and the Art of Motorcycle Maintenance’ author Robert Pirsig uses the chemical process of crystal formation to describe how a small thought can ‘seed’ the formation of larger ideas.  Recently I was reminded of Pirsig’s analogy when a random observation got me to thinking.   In this case, the seed crystal was a question asked to me about the success rate of Appalachian shale gas wells.  Later in the day I became aware that the seed had been growing in the quiet of the dim recesses of my mind.  Apparently, it had fallen into a goop of tidbits of information that had collected there about the nature of the oil and gas industry and the impact that Steven Jobs had on modern life.

Since the untimely passing of Steven Jobs, many have chronicled the ways in which his ideas changed technology.   Like Watt’s steam engine, Bell’s telephone and Edison’s light bulb, Jobs’ achievement is a stunning and revolutionary technologic leap forward.   However, it is not the mere invention of technology that separates the everyday from the revolutionary; instead it is the degree to which Watts, Bell, Edison and Jobs changed every facet of our lives, the way we relate to one another, and the way we interact with our environment. 

So it is with shale gas.  Sure the technological advances, like the ability to bend heavy steel pipes to drill horizontal and ‘turn-azontial’ holes, are really cool.  But, the revolutionary part of shale gas is the way it is changing the oil and gas industry.  For instance, the shales being tapped are thought to be the sediments in which the hydrocarbons formed.  Except where the rock has ‘cooked’ too much from tectonic forces, or where it outcrops at the surface, it will contain gas.   In fact, Range Resources reported that, in the 3^rd quarter of 2011, they drilled 77 wells and ‘[a] 100% success rate was achieved’.

This is a significant change for an industry used to risk.   In the past an exploration and production company would sort through huge lease holdings hoping to find economic plays.  Today’s shale gas companies, free of much of the risk, see the lease holding as an investment.  In a recent Forbes magazine interview Chesapeake CEO Aubrey McClendon said ‘…the game changed…and land acquisition became the key to capturing the greatest value from the unconventional play.  [A] lease situated in the heart of any shale play is essentially a very cheap call option on the right to develop oil and natural gas…’ 

When such significant changes are being wrought to the very foundation of an entire industry it is unlikely that the change will stop there.  Markets will shift, geopolitics will reshape themselves, and the way we live will be affected.  Unless I’m reading the tea leaves wrong, shale gas is ‘revolutionary’ and as important of a leap forward as the Apple computer or the I-Phone. 

Talking Consolidation - with Mike Fischel

By Mike Fischel, ENP - Vice President, Business Development

Last month, I had the pleasure of talking to a group of public safety communications professionals from New England and New York about 9-1-1 and dispatch center consolidation  at the Atlantic Coast Association of Public Safety Communications Officials Conference .  This is an important and growing issue in the public safety field because of the challenges that 9-1-1 and  centers face to improve service, coordinate services, and achieve cost efficiencies in the face of a difficult economy,  new technologies, and a growing expectation from the public about the capabilities of  the “9-1-1 System” to protect life and property.  

The expertise of our staff members have lead us to believe that 9-1-1 consolidation initiatives can provide significant benefits to the public, telecommunicators and first responders if approached in the right way.

These initiatives typically are comprised of three phases:  Feasibility Study, Implementation Planning, and the actual transition to consolidated operations.  The feasibility study phase is a critical step in any initiative because it examines current operations, service, cost, technologies, and facilities in order to determine options, requirements, political environment, and will to support a consolidation among potential municipalities and/or agencies. This study usually is the basis for making decisions regarding the practicality to move forward with detailed planning for the consolidation of 9-1-1/dispatch  centers.  

If the decision is made to move forward with a consolidation, there are several key requirements that are essential to the planning process.  They include development of a governance agreement that addresses authority, control, and policies for the consolidated organization.  A funding approach will be required to establish the source of funds to establish the new organization and its continued operations.  Service offerings and levels of performance must be established. Staffing and human resources including pay, benefits, position classifications, training, and quality assurance programs must be determined.  Finally facility and technology requirements must be specifically defined and secured. 

In our work supporting these initiatives, we have found there are some common lessons to be considered. 

• First, consolidation initiatives based solely on the expectation of saving money are not typically successful.  Successful initiatives are more often based on the desire to improve service, capacity, coordination, and interoperability among agencies and municipalities. 
• Another important lesson is that leadership and program management established early in the consolidation process is a key predictor of a successful consolidation process. 
• Finally, we have found it is helpful to view a consolidation  initiative as a once in a lifetime opportunity to establish an organization and program of services that will bring substantial improvement to the delivery of emergency communication services to the public and first responders.
