New technical standards are now available from NFPA

The National Fluid Power Association (NFPA) represents 250 U.S. and multinational manufacturers of hydraulic and pneumatic products and systems. Based in Milwaukee, Wisconsin, USA, NFPA coordinates standards development for fluid power at the industry, national and international levels. NFPA is Secretariat of the Fluid Power Committee B93, an independent standards development committee accredited by the American National Standards Institute. NFPA also serves as the secretariat of ISO Technical Committee 131 (ISO/TC 131), which is responsible for the development of international standards for fluid power. ISO, ANSI and NFPA standards are intended as guides to aid the manufacturer, the consumer and the user.

Twelve new technical standards have recently been published and are now available from the National Fluid Power Association (NFPA). Each new standard is described briefly below.

ISO 3601-1:2002 Fluid power systems—O-rings—Part 1: Inside diameters, cross-sections, tolerances and size identification code. This part of ISO 3601 specifies the inside diameters, cross-sections, tolerances and size identification code for O-rings used in fluid power systems for general purpose applications (series G), as well as for aerospace and similar applications (series A). The dimensions and tolerances specified in this part of ISO 3601 are suitable for any elastomeric material, provided that suitable tooling is available.

ISO 6162-1:2002 Hydraulic fluid power—Flange connectors with split or one-piece flange clamps and metric or inch screws—Part 1: Flange connectors for use at pressures of 3,5 MPa (35 bar) to 35 MPa (350 bar), DN 13 to DN 127. This part of ISO 6162 specifies complete general and dimensional specifications for flange heads, split flange clamps (FCS), one-piece flange clamps (FC) and ports applicable to four-screw, split and one-piece flange clamp type tube and hose connectors for use at pressures of 3,5 MPa (35 bar) to 35 MPa (350 bar).
Price per copy: $51.00 (list), $44.00 (NFPA members)

ISO 6162-2:2002 Hydraulic fluid power—Flange connectors with split or one-piece flange clamps and metric or inch screws—Part 2: Flange connectors for use at pressures of 35 MPa (350 bar) to 40 MPa (400 bar), DN 13 to DN 51. This part of ISO 6162 specifies complete general and dimensional specifications for flange heads, split flange clamps (FCS), one-piece flange clamps (FC) and ports applicable to four-screw, split and one-piece flange clamp type tube and hose connectors for use at pressures of 35 MPa (350 bar) to 40 MPa (400 bar).
Price per copy: $51.00 (list), $44.00 (NFPA members)

ISO 6195:2002 Fluid power systems and components—Cylinder-rod wiper-ring housings in reciprocating applications—Dimensions and tolerances. This International Standard specifies dimensions and tolerances of housings for wiper rings used in reciprocating rod applications for fluid power cylinders.
Price per copy: $44.00 (list), $37.00 (NFPA members)

ISO 6605:2002 Hydraulic fluid power—Hoses and hose assemblies—Test methods (second edition). This International Standard specifies uniform test methods for evaluating the performance of hose assemblies (hoses and attached hose fittings) used in hydraulic fluid power systems.
Price per copy: $40.00 (list), $34.00 (NFPA members)

ISO/TR 10949:2002 Hydraulic fluid power—Component cleanliness—Guidelines for achieving and controlling cleanliness of components from manufacture to installation (second edition). This Technical Report gives guidelines for achieving, evaluating and controlling the cleanliness of hydraulic fluid power components from the time of their manufacture through to their installation in a hydraulic fluid power system. This document can be used to ensure that hydraulic components are cleaner when they arrive at installation, and cleaner components contribute to cleaner, and thus more reliable, hydraulic systems.
Price per copy: $36.00 (list), $31.00 (NFPA members)

ISO/TR 16144:2002 Hydraulic fluid power—Calibration of liquid automatic particle counters—Procedures used to certify the standard reference material SRM 2806. This Technical Report describes the procedures used by the U. S. National Institute of Standards and Technology (NIST) for the certification of the calibration material SRM 2806, which is used in the primary calibration of liquid automatic particle counters.
Price per copy: $51.00 (list), $44.00 (NFPA members)

ISO 18413:2002 Hydraulic fluid power—Cleanliness of parts and components—Inspection document and principles related to contaminant collection, analysis and data reporting. This International Standard specifies the content of an inspection document that includes both the cleanliness requirement for the specified part or component and the inspection method to be used for evaluating its cleanliness level. This standard can improve communication about component cleanliness between suppliers and users of hydraulic components and provides valuable information about how cleanliness can be specified and verified, subject to agreement.
Price per copy: $68.00 (list), $58.00 (NFPA members)

NFPA/T2.13.2 R4-2002 Hydraulic fluid power—Fire resistant fluids—Information report on company trade names. This information report has been prepared to aid the user in identifying a fire resistant fluid as to its type and supplier.
Price per copy: $33.00 (list), $23.00 (NFPA members)

NFPA/T2.30.4 R1-2002: Recommended practice—Fluid power systems—Application guidelines for selection of fluid power position transducers. This document identifies the factors involved in selecting a reliable and functional position transducer. Because this standard is an application guideline, it is available for free PDF download on the NFPA website at www.nfpa.com, in the Standards/Technical Resources section.

NFPA/T3.12.17-2002 Recommended practice—Pneumatic fluid power—Filters, regulators and lubricators—Application guidelines addresses the application of filters, regulators, and lubricators in a pneumatic fluid power system. This recommended practice also provides guidelines for the selection, sizing, installation, operation, and other good practices for pneumatic filters, regulators and lubricators. Because this standard is an application guideline, it is available for free PDF download on the NFPA website at www.nfpa.com, in the Standards/Technical Resources section.

NFPA/T3.19.25 R1-2002 Information report—Fluid power systems—Sealing devices—Storage, handling and installation of elastomeric seals and exclusion devices. This new information report addresses the storage, handling and installation of elastomer seals in general terms.
Price per copy: $33.00 (list), $23.00 (NFPA members)
