These standards represent a starting point or rough gauge to apply to mostmachinery using an absolute vibration reference level by machine condition that isbased on both experience & historical data across many industries and machinetypes. Some examples are as follows:
1) IRD 10816 Charts (Casing Measurements)2) Bernhard Chart (Casing Measurements)3) Vibration Institute Standards (Casing Measurements)4) Update International Standards (Casing Measurements)5) Blake Chart (Casing Measurements)5) Blake Chart (Casing Measurements)6) ISO 10816-1 Standard (Casing Measurements)7) API 612 Standard (Shaft Displacement)8) Dresser-Clark-Jackson Chart (Shaft Displacement)
PROS: No prior machine history is required to perform a general assessment of amachine’s health.
CONS: Fail to account for the vast differences between machine types, bearing types,stiffnesses, system mass, base types, machine speeds, loading, etc.

These machine-specific standards improve in relevance versus general standards for most realproblems as they are adjusted to best fit the unique design and operation of specific types ofmachinery. They are typically based on real historical data from equipment fitting thedescription involved. Some examples are as follows:
1) Technical Associates Standards
2) Sohre-Erskine R/C Standards (shaft vibration, fluid film bearings)
3) ISO 7919 (shaft vibration, fluid film bearings)
4) OEM Specifications
PROS:
a) Can be applied to plant equipment from the beginning of a condition monitoring program.No prior machine history is necessary to make a basic assessment of a machine’s condition.
b) b) Takes into account the basic differences between different types of machinery & base types(ie: pump versus fan, rigid versus isolated base, etc).
CONS:
Your plant’s machinery, process, loading, speed, mounting, etc is no doubt unique in some waysthat can make your final vibration levels end up on the high or low side of these standardswithout anything being wrong with the equipment or in some cases with a whole lot wrong withthe equipment.

R/C Method (fluid-film bearings) Erskine & Sohre have suggested the use of relative shaftvibration (R) and bearing clearance (C) for the evaluation of the condition of machines withfluid film bearings. The state of the bearing is judged by the ratio R/C and rotor speed.This provides a basis that is directly applicable to the specific machine in question. Erskinedivided his results into two speed categories — turbine generators (3,600 RPM) andcentrifugal compressors (10,000 RPM). These could also be applied to other machines suchas motors & pumps with similar speeds. The work of Erskine was refined by Eshlemanand Jackson.

• Before applying these shaft vibration standards, pleasetake into account both the available bearing clearance &the type of fluid film bearing used (use common sense).
• For example, if the standard says 100 micrometersvibration is ok and you only have 120 micrometersbearing clearance to work with, you may want to shiftthe boundary zones as needed (ie: B becomes C or Cbecomes D, etc).becomes D, etc).
• Be aware of not only how much vibration is occurring,but where it is occurring relative to the bearing geometry(shaft position + orbit).

ABSTRACT
Standards are criteria established by authority, custom, or general consent. Good reference standards represent a broad consensus of opinion among users, and are therefore widely accepted and applied. Furthermore, standards should be clear, concise, and easily understood. Numerous standards exist to guide or govern vibration monitoring and analysis, including some that establish classifications for machinery vibration, how measurements should be made, and how the acquired data should be analyzed. This paper will introduce a selection of applicable reference standards, and provide commentary and opinion on each with respect to suitability for various industrial applications. Keywords: vibration, standards 1. INTRODUCTION Standards are documented agreements containing technical specifications or other precise criteria to be used consistently as rules, guidelines, or definitions of characteristics, to ensure that materials, products, processes and services are fit for their purpose. A good standard represents consensus of opinion, is easy to use, and contains no ambiguities or loopholes. 2. ISO STANDARDS FOR VIBRATION MONITORING AND ANALYSIS 2.1 The ISO Standards System In the field of machinery vibration monitoring and analysis, a variety of relevant standards are developed and published by ISO (International Organization for Standardization). ISO is a worldwide federation of national standards bodies from 145 countries, and considers itself a bridge between the public and private sectors. A member body of ISO is the national body "most representative of standardization in its country". Only one such body for each country is accepted for ISO membership. Member bodies are entitled to participate and exercise full voting rights on any technical committee of ISO. In addition to ISO, various trade organizations such as National Electrical Manufacturers Association (NEMA) and American Petroleum Institute (API) have developed and published vibration standards, which are widely accepted and applied (and therefore relevant). In most cases, these standards have been developed by consensus of consumers and manufacturers, and their use is considered voluntary. ISO standards are developed by technical committees comprised of experts on loan from the industrial, technical, and business sectors. The experts participate as national delegations, selected by the ISO national member institute for their respective countries. Technical committees meet to discuss, debate, and argue until they reach consensus on a draft agreement, which is circulated as a Draft International Standard (DIS) to all ISO members for comment and
balloting. After taking into account any feedback, the ISO members formulate their position on the draft standard. Following an affirmative vote†, the document, including any modifications, is re-circulated to the ISO members as a Final Draft International Standard (FDIS) for 2nd ballot. If that vote is positive, the document is then published by ISO as an International Standard. Most of the ISO standards for machinery vibration monitoring and analysis are guided by technical committee TC108, Mechanical vibration and shock. TC108 is comprised of 22 Participating (P-member) countries and 25 Observer countries. As of May 2003, there are a total of 98 published ISO standards related to TC108 and its SCs (subcommittees). Noteworthy subcommittees include; SC1, Balancing, including balancing machines, SC2, Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures, and SC5, Condition monitoring and diagnostics of machines. The stated scope of TC108 is “Standardization in the field of mechanical vibration and shock and condition monitoring and diagnostics of machines, including;
• terminology; • excitation by sources, such as machines and vibration and shock testing devices; • elimination, reduction and control of vibration and shock, especially by balancing,
isolation and damping; • measurement and evaluation of human exposure to vibration and shock; • methods and means of measurement and calibration; • methods of testing; • methods of measurement, handling and processing of the data required to perform
condition monitoring and diagnostics of machines 2.2 ISO Standards For Evaluation Of Vibration Severity Standards for evaluation of vibration severity are considered one of the most important activities of ISO/TC108. Unfortunately, due to the range of machinery categories and classifications, it may also be the most confusing. A wide variety of published standards describe acceptable vibration limits, including the ISO/7919 series (5 parts) “Mechanical vibration of non-reciprocating machines – Measurements on rotating shafts and evaluation criteria” and the ISO/10816 series (6 parts) “Mechanical vibration – Evaluation of machine vibration by measurements on non-rotating parts” As detailed in Table 1, ISO 7919-1 is the basic document describing the general requirements for measurement and evaluation of machinery vibration using shaft measurements. Similarly, ISO 10816-1 is the basic document describing the general requirements for evaluating machinery vibration using casing and/or foundation measurements. Subsequent parts of each series of documents apply to different classes and types of machinery, and include specific evaluation criteria used to assess vibration severity. † In accordance with ISO directives, Part 1, Procedures, 2001, an enquiry draft (DIS) is approved if
a) a two-thirds majority of the votes cast by P-members of the technical committee or subcommittee are in favour, and b) not more than one quarter of the total votes cast are negative.

Table 1 • ISO Standards for Evaluation of Vibration Severity† The evaluation procedures in the ISO/7919 and ISO/10816 series of standards are limited to broadband measurements, without reference to frequency components or phase§. Measurement procedures are detailed in Part 1: General Guidelines of each series, including shaft relative, shaft absolute, and pedestal vibration measurements. At the May 13 – 16, 2003 meeting of ISO/TC108/SC2, Professor Hiroshi Kanki of Japan proposed “Guidelines for selecting vibration evaluation methods by measurement on the rotating shaft and/or on non-rotating parts”, referred to as the “umbrella document”. The scope of the umbrella document is to provide general guidelines for selecting the appropriate vibration standards for a specific machinery classification. The proposed method includes 2 key evaluation criteria; 1) shaft displacement from the journal centerline, and 2) stiffness ratio of pedestal to bearing (which determines the ratio of the shaft relative vibration to the pedestal vibration), as detailed in Figures 1 and 2, below. This was proposed as a work item, and will essentially become a standard on how to select and apply the standards (proposed by ISO/TC108/WG2 as Part 0 of ISO/7919 and/or ISO 10816). † Early ISO vibration severity standards, ISO/2372, ISO 2954, and ISO 3945 “Mechanical vibration of large rotating machines with speed range from 10 to 200 r/s – Measurement and evaluation of vibration severity in situ”, have been superseded by the ISO 7919 and 10816 series. ‡ ISO/10816-7 was developed by Joint Working Group (JWG) 9 of ISO/TC108/SC2 and ISO/TC115 (Pumps), and is presently at the Committee Stage. The Committee Draft (CD) was circulated to P-member countries for comment and vote in January 2003. § Narrowband measurements and spectral analysis are to be dealt with in the ISO/13373 series “Condition monitoring and diagnostics of machines – Vibration condition monitoring”.
Figure 1 • Flow Diagram for selection of measurements and evaluation of vibration severity
Figure 2 • Dynamic Stiffness Ratio Diagram In general, machines equipped with rolling element bearings will tend to have high bearing stiffness, a stiffness ratio less than 1, and are better suited to vibration measurements at the pedestal and/or casing. Conversely, machines using fluid film bearings and supported on relatively soft pedestals, will have a much higher stiffness ratio, and are better suited to shaft vibration measurements. Table 2, below, shows example dynamic stiffness ratios, and the applicable reference standard.

2.3 ISO Standards For Vibration Measurements
ISO 13373-1:2001 Condition monitoring and diagnostics of machines — Vibration condition monitoring — Part1: General procedures provides general guidelines for the measurement of machinery vibration for condition monitoring. Recommendations are provided for the following;
• measurement methods and parameters• transducer selection, location, and attachment• data collection• machine operating conditions• vibration monitoring systems• signal conditioning systems• interfaces with data processing systems• continuous and periodic monitoring
Due to the wide variety of approaches to condition monitoring, specific topics will be addressed in more detail in additional parts of 13373. At the time of writing this article, Part 2: Processing, analysis and diagnostics is at the committee draft stage.
ISO 17359:2003 Condition monitoring and diagnostics of machines — General guidelines sets out guidelines for the general procedures to be considered when setting up a condition monitoring program.
2.4 ISO Standards For Training and Certification
ISO standards for personnel training and certification are a relatively new and significant initiative for ISO/TC108. In August, 2003, ISO 18436-2:2003 Condition monitoring and diagnostics of machines — Requirements for training and certification of personnel — Part 2: Vibration condition monitoring and diagnostics received an affirmative vote at the FDIS stage, and was affirmed as an international standard. 18436-2 describes a 4-category scheme for certification of vibration analysis personnel who perform condition monitoring and diagnostics. Certification candidates are required to meet prerequisite education, training, and experience, and successfully pass a qualification examination.
Future parts of the 18436 series will include;
1. Part 1: Requirements for certifying bodies and the certification process2. Part 3: Requirements for training bodies3. Part 4: Lubrication management and analysis4. Part 5: Thermography5. Part 6: Diagnostics and prognostics6. Part 7: Condition monitoring specialists7. Part 8: Balancing
