Hydraulic fluid power. Electrically modulated hydraulic control valves - Test methods for four-port directional flow-control valves Ingestion-build-2021391 Scope This part of ISO 10770 describes methods for determining the performance characteristics of electrically modulated, hydraulic, four port directional flow control valves. This type of electrohydraulic valve controls the direction and flow in a hydraulic system.

Due to the strong interrelation between the product and its corresponding graphical representation

PD IEC/TR 62517 gives an outline of the recommended magnetizing field strengths for modern permanent magnets

2 Preparation of samples and test pieces

PD CEN/TS 17274 on explosivity and flammability of powders containing nano-objects nanotechnologies is useful for:

a) Gutters

BS EN ISO 13337 specifies the characteristics of slotted spring-type straight pins

of whole populations

BS EN ISO 4623-1:2018 supersedes BS EN ISO 4623-1:2002

cleaning mixtures

By using the requirements specified by BS EN 13832‑3 the user can produce an improved quality of degradation resistant and permeation resistant footwear and ensure protection to the wearer from hazardous chemicals to gain higher customer satisfaction

The rationale contained in this guidance may also be used to help modify test severities when the conditions found in IEC 60721‑3 do not adequately describe a particular environment or application
