Hydraulic fluid power — Fluid contamination — Determination of particulate contamination by the coun...
This International Standard specifies methods for determining the level of particulate contamination in liquids used in hydraulic systems by counting the number of particles deposited on the surface of a membrane filter using an optical microscope. It includes particle counting by two manual methods and image analysis, using either transmitted or incident lighting systems.
Particle sizes greater…
1.1 Scope
1.1.1
This standard applies to newly produced gas appliance connectors constructed entirely of new, unused parts and materials that:
a. Are intended for use with gas-fired commercial cooking equipment that may be mounted on casters or otherwise be subject to movement for cleaning, and with other large and heavy gas-fired equipment that may be moved;
b.…
This International Standard give guidelines for the inspection, recording procedures, packaging and storage of products, assemblies and components made from vulcanized or thermoplastic rubber prior to being put into circulation.
It is applicable to both solid and cellular rubber products prepared from dry raw rubber, latex or other sources. It is subject only to the requirements or…
Ships and marine technology — Marine environmental protection — Adaptor for joining dissimilar boom ...
ISO 16446 specifies a universal method for the joining of oil-spill-containment booms with dissimilar connectors through the use of a standard adaptor with prescribed mating specifications. This International Standard does not intend to replace the design of existing connectors.
ISO 16446 does not purport to address all of the safety concerns, if any, associated with its use. It is the…
ISO 492 specifies tolerances for boundary dimensions (except chamfer dimensions) and the running accuracy of radial rolling bearings specified in ISO 15, ISO 355 and ISO 8443.
This International Standard does not apply to certain radial bearings of particular types (e.g., drawn cup needle roller bearings) or for particular fields of application (e.g., airframe bearings and instrument precision…
Road vehicles — Measurement of road surface friction
This International Standard specifies test methods for determining the characteristic longitudinal friction force
values of paved surfaces using either a standard reference test tyre or the tyre of a vehicle under test. General test
procedures and their validity are presented for determining peak- and slide-braking coefficients on actual test
surfaces, where the surface conditions are determined…
Safety of machinery — Hygiene requirements for the design of machinery
This International Standard specifies hygiene requirements of machines and provides information for the intended use to be provided by the manufacturer. It applies to all types of machines and associated equipment used in applications where hygiene risks to the consumer of the product can occur.
This International Standard does not cover requirements relative to the uncontrolled egress of…
Condition monitoring and diagnostics of machines — General guidelines on using performance parameter...
This International Standard describes the general conditions and procedures for recording, assessment, evaluation and diagnostics of machine condition by measuring parameters related to machine performance, condition and safety, including thermal, electrical and hydraulic parameters where applicable.
The procedures relate to operational monitoring of machines, and include all components and sub-…
Animal and vegetable fats and oils — Determination of polyethylene-type polymers
This International Standard specifies the reference method for the determination of polyethylene-type polymers in
animal and vegetable fats and oils.
It has been established that below 50 mg of polymers per kilogram the precision of the method is insufficient (see the
results for tallow 1 in Table A.1).
This method is used for animal fats and oils in particular.
Animal and vegetable fats and oils — Determination of content of polar compounds
This International Standard describes a method for the determination of the content of polar compounds in animal and vegetable fats and oils.
Polar compounds are formed during the heating of fats and oils and thus the method serves to assess the deterioration of frying fats and oils with use.
