Irrigation equipment. Safety devices for chemigation - Chemigation valve assemblies from DN 75 (3”) to DN 350 (14”)1 Scope This part of ISO 13693 specifies the construction and performance requirement and test methods for metal bodied chemigation valves with water at temperatures not exceeding 50 C, which might contain fertilizers and chemicals of the types and concentration used in agriculture. The valve is designed to prohibit backflow caused by either back pressure or back siphonage. It is not designed for use in potable water systems. It is not to be confused

this standard does not specify a test procedure for this because it has not been possible to devise an objective and reproducible test

• Protection from burning

Rotodynamic pumps A pump is a mechanical device generally used for raising liquid from a lower level to a higher one

Some of the definitions represent discussion points aimed at refocusing their terms in the specific context of computed tomography

such that results obtained on different types of apparatus are correlatable

BS EN 60079-1:2004 provides information on:

- Type IV: Inflatable craft propelled by sail with a maximum sail area of 6 m2 (see normative annex B)

This document is intended to assist the design of oil-based lubrication systems for hydrodynamic plain bearings mainly to be used in large-scale rotating machinery for power generation

BS EN 61158-5-16 provides migration paths from previously existing industrial communications protocols

The main purpose of ISO 8289 is to provide low-voltage test methods for detecting and locating defects

provided its surfaces are flat and non-defusing
