Aerospace series — Hydraulic filter elements — Test methods — Part 1: Test sequence
ISO 14085-1:2015 specifies a test sequence for evaluation of characteristics of the hydraulic fluid filter elements under standard conditions.
ISO 14085-1:2015 is not intended to qualify a filter element under replicate conditions of service; this can only be done by a specific test protocol developed for the purpose, including actual conditions of use, for example the operating fluid or…
Aerospace series — Hydraulic filter elements — Test methods — Part 2: Conditioning
ISO 14085-2:2015 specifies
- a procedure to thermally condition a hydraulic filter element to presumed aerospace hydraulic system stresses,
- a test procedure to complete cold soaks, hot soaks, and temperature variation in a combined manner, and
- a test procedure to simulate cold starts.
ISO 14085-2:2015 is not intended to qualify a filter element under replicate conditions of…
Aerospace series — Hydraulic filter elements — Test methods — Part 4: Verification of collapse/burst...
ISO 14085-4:2015 describes a method for verifying the collapse/burst pressure rating of an aerospace hydraulic fluid power filter element. This represents the capability of a filter element to withstand a designated differential pressure in the normal (intended) direction of flow, created by flowing contaminated fluid through the filter element until either collapse/burst occurs or the maximum…
Aerospace series — Hydraulic filter elements — Test methods — Part 5: Resistance to flow fatigue
ISO 14085-5:2015 specifies a method for determining the resistance of a filter element to flow fatigue caused by varying flow through the filter in various stages of the filter contaminant loading process. The filter is subjected to a uniform varying flow rate for a specified number of cycles, at a number of predetermined differential pressures.
Although the number of cycles and differential…
Aerospace series — Hydraulic filter elements — Test methods — Part 3: Filtration efficiency and rete...
ISO 14085-3:2015 describes two methods to measure in repeatable conditions the filtration efficiency of filter elements used in aviation and aerospace hydraulic fluid systems. It can be applied when evaluating the overall characteristics of a filter element per ISO 14085‑1, or separately.
Since the filtration efficiency of a filter element can change during its service life as it is clogging,…
Information technology - Device control and management - Part 2: Specification of Device Control and...
ISO/IEC 17811-2:2015 provides the specification of Device Control and Management Protocol (DCMP), which is an application-layer protocol used to control and manage the various devices. DCMP supports the device and network status information retrieval, device initialization, firmware and software update, file transmission, and so on. This part of ISO/IEC 17811 specifies the protocol operations and…

Information technology — Radio frequency identification for item management — Part 4: Parameters for...
ISO/IEC 18000-4:2015 defines the air interface for radio frequency identification (RFID) devices operating in the 2,45 GHz Industrial, Scientific, and Medical (ISM) band used in item management applications. It provides a common technical specification for RFID devices that can be used by ISO committees developing RFID application standards. It is intended to allow for compatibility and to…
