Pump system energy assessment (ISO/ASME 14414:2019)
This document sets the requirements for conducting and reporting the results of a pumping system energy assessment (hereafter referenced as "assessment") that considers the entire pumping system, from energy inputs to the work performed as the result of these inputs. The objective of a pumping system energy assessment is to determine the current energy consumption of an existing system and identify ways to improve system efficiency. These requirements consist of — organizing and conducting an assessment, — analysing the data from the assessment, and — reporting and documenting assessment findings. This document is designed to be applied, to open and closed loop pumping systems typically used at industrial, institutional, commercial, and municipal facilities, when requested. This document is focused on assessing electrically-driven pumping systems, which are dominant in most facilities, but is also applicable with other types of drivers, such as steam turbines and engines. The document does not a) specify how to design a pumping system, b) give detailed qualifications and expertise required of the person using the International Standard although provides a list of body of knowledge in Annex C, c) address the training or certification of persons, d) specify how to implement the recommendations developed during the assessment, but does include requirements for an action plan, e) specify how to measure and validate the energy savings that result from implementing assessment recommendations, f) specify how to make measurements and how to calibrate test equipment used during the assessment, g) specify how to estimate the implementation cost or conduct financial analysis for recommendations developed during the assessment, h) specify specific steps required for safe operation of equipment during the assessment. The facility personnel in charge of normal operation of the equipment are responsible for ensuring that it is operated safely during the data collection phase of the assessment, i) address issues of intellectual property, security, confidentiality, and safety.

Polyolefin pipes and fittings -- Determination of carbon black content by calcination and pyrolysis -- Test method
This document specifies test methods for the determination of the carbon black content of polyolefin compositions used in particular for the manufacture of pipes and fittings, and provides a basic specification for polyethylene pipes and fittings. This document applies equally to the material for manufacture and to any material taken from a pipe or fitting.

Crosslinked polyethylene (PE-X) and crosslinked medium density polyethylene (PE-MDX) -- Effect of time and temperature on expected strength
This document specifies the minimum values for expected strength as a function of time and temperature in the form of reference lines, for use in calculations on crosslinked polyethylene (PE-X) pipes and crosslinked medium density polyethylene (PE-MDX) pipes. NOTE 1 This document is applicable for pipes with the minimum level of crosslinking after production in accordance with Clause 4. NOTE 2 The density range for medium density polyethylene is 926 kg/m3 to 940 kg/m3 in accordance with ISO 17855-1:2014[2].

Pump system energy assessment (ISO/ASME 14414:2015)
The purpose of this standard is to prepare methodologies for the evaluation of the efficiency of pump systems. The pump systems of immediate interest are those in Buildings, Water Utilities and Chemical processes. This International Standard deals with evaluation of systems where a significant component of the energy consumed is by pumps on water applications (centrifugal, mixed flow and axial pumps). It may be applied to pumps of any size and to any pumped liquids that behave as clean cold water. This standard may also be used with care with systems with pumps for sludges, slurries or viscous liquids or those with suspended solids where special design rotodynamic and positive displacement pumps are used.

Rubber hoses, textile-reinforced, for general-purpose water applications - Specification (ISO/DIS 1403:2019)
This document specifies the requirements for three types of general-purpose textile-reinforced rubber water hose with an operating temperature range of −25 °C to +70 °C and a maximum working pressure of up to 2,5 MPa (25 bar).These hoses are not intended to be used for conveyance of potable (drinking) water, for washing-machine inlets, as firefighting hoses, for special agricultural machines or as collapsible water hoses.These hoses can be used with additives which lower the freezing point of water.
