This document specifies requirements for two types, seven classes and three grades of wire- or textile-reinforced dredging hoses with nominal sizes ranging from 100 to 1 300. Within each class, all grades and sizes have the same maximum working pressure. Such hoses are suitable for the delivery or suction of seawater or freshwater mixed with silt, sand, coral and small stones with a specific gravity in the range from 1,0 to 2,3 at ambient temperature ranging from -10 °C to +40 °C or for low-temperature hoses (designated -LT) ranging from -20 °C to +40 °C. This document covers two types of hose, as follows:

—   type 1: floating type, for delivery only, which includes flotation material to give the hose buoyancy;

—   type 2: submarine type for delivery and suction.

This document does not specify requirements concerning the service life of hoses or hose assemblies. Specifying such requirements is the responsibility of the customer, in consultation with the hose manufacturer.

This part of ISO 21013 provides separate calculation methods for determining the required mass flow to be relieved for each specified conditions described in the following table:

Good engineering practice based on well-established theoretical physical science needs to be adopted to determine the required mass flow where an appropriate calculation method is not provided for an applicable condition. Recommendations for pressure relief devices for cryostats are given in Annex A.

This document provides basic requirements for gearboxes to operate industrial valves for manual and automated on/off and modulating duties, this includes manual override gearboxes. It includes guidelines for classification, design and methods for conformity assessment. It does not cover gear systems which are integral part in the design of valves and subsea gearboxes. Other requirements or conditions of use different from those indicated in this document are agreed between the purchaser and the manufacturer or supplier (first party), prior to order.

ISO 3994:2014 specifies the requirements for three types of helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of water, weak aqueous chemical solutions and abrasive solids and slurries, for use in the ambient temperature range from −10 °C to 55 °C. The three types of hose are for light-, medium- and heavy-duty applications.

This document specifies requirements for the attachment of part-turn actuators, with or without gearboxes, to industrial valves. The attachment of part-turn actuators to control valves in accordance with the requirements of this document is subject to an agreement between the supplier and the purchaser. This document specifies: —    flange dimensions necessary for the attachment of part-turn actuators to industrial valves [see Figures 1 a) and 1 c)] or to intermediate supports [see Figures 1 b) and 1 d)]; —    driving component dimensions of part-turn actuators necessary to attach them to the driven components; —    reference values for torques for interfaces and for couplings having the dimensions specified in this document. The attachment of the intermediate support to the valve is out of the scope of this document.

This document describes the use of modal acoustic emission (MAE) testing during periodic inspection and testing of hoop wrapped and fully wrapped composite transportable gas cylinders and tubes, with aluminium-alloy, steel or non-metallic liners construction, intended for compressed and liquefied gases under pressure.

This document addresses the periodic inspection and testing of composite cylinders constructed to ISO 11119‑1, ISO 11119‑2, ISO 11119‑3, ISO 11515 and ISO/TS 17519 and can be applied to other composite cylinders designed to comparable standards when authorized by the competent authority.

Unless noted by exception, the use of “cylinder” in this document refers to both cylinders and tubes.

This document specifies the requirements for the attachment of multi-turn actuators to valves. Throughout this document, “actuator” can be understood as “actuator and/or gearbox” providing a multi-turn and/or linear output. It specifies: —    flange dimensions necessary for the attachment of actuators to industrial valves [see Figure 1 a)] or to intermediate supports [see Figure 1 b)]; —    those driving component dimensions of actuators which are necessary to attach them to the driven components; —    reference values for torque and thrust for flanges having the dimensions specified in this document.

 This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the rehabilitation by means of renovation and trenchless replacement of underground gas supply networks. It is applicable to polyethylene (PE) pipes, fittings and assemblies, as manufactured and as installed. It is not applicable to the existing pipeline. It is applicable to technique families for renovation:

— lining with continuous pipes;

— lining with close-fit pipes; and technique families for trenchless replacement:

— pipe bursting and pipe extraction;

— horizontal directional drilling and impact moling. and intended to be used at an operating temperature of 20 °C as the reference temperature.

NOTE Annex A. For applications operating at constant temperatures greater than 20 °C and up to 40 °C, see ISO 4437-5:2024,

This document is applicable to:

— PE solid wall single layered pipes (nominal outside diameter, dn), including any identification stripes;

— PE pipes with co-extruded layers on either or both the outside and inside of the pipe (total outside diameter, dn), as specified in Annex D, where all layers have the same MRS rating.

Furthermore, when used with lining with continuous pipes and trenchless replacement this document is applicable to:

— PE coated pipes (outside diameter, dn) having a peelable, contiguous, thermoplastics additional layer on the outside of the pipe (“coated pipe”), as specified in Annex D.
