This specification covers manually operated fueling hose reels for use with collapsible and noncollapsible hose. Fueling hose reels shall be of one of the following types as specified: type 1, type 2, type 3, and type 4. The hose reel shall be of a durable, rigid construction, as light in weight and compact as practicable. The reel drum may have either smoothly formed flat sides or suitable spoke ribs, so formed as not to damage the hose. Reels shall be provided with a holding brake to lock the reel in any position. The reel shall be fitted with a device for clamping the hose nozzle securely to the reel to prevent unwinding of the hose and damage to the nozzle. The reel hub discharge shall be angled to provide a smooth tangential contact of the hose with the reel drum. The reel shall have an aromatic fuels tight rotating joint between reel inlet connection and the rotating hub on the reel drum. The reel inlet connection shall be flanged, the flange being part of the rotating swivel joint. Hydrostatic tset and operating test shall be performed to meet the requirements prescribed.1.1 This specification covers manually operated fueling hose reels for use with collapsible and noncollapsible hose.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 The following precautionary caveat pertains only to the test methods portion, Section 12 of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers the standard for front wheel retention systems for all bicycles equipped with manually operated retention systems such as a quick release. This specification is only for bicycles equipped with manually operated retention systems, and does not apply to tool-operated wheel fastening systems. Primary retention and secondary retention tests shall be performed to conform to the specified requirements.1.1 These test methods and specifications cover the standard for front wheel retention systems for all bicycles equipped with manually operated retention systems such as a quick release.1.2 This specification is only for bicycles equipped with manually operated retention systems, and does not apply to tool-operated wheel retention systems.1.3 The intent of this specification is to define the performance of primary and secondary wheel retention systems, with the focus on preventing unintended wheel separation and prevention of unintended contact of the retention system with the disc brake rotor or wheel.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.
