1 Scope 1.1 General This Standard covers two types of polypropylene (PP) pipe and fittings – polypropylene random copolymer (PP-R) and polypropylene random copolymer with modified crystallinity and temperature resistance (PP-RCT) intended for use in pressure applications such as hot and cold potable water distribution systems, process piping, reclaimed/recycled water systems, water service,…

1 Scope 1.1 General This Standard covers polyamide (PA) pipe, tubing, and fittings for use in gas mains and services, including the gathering, transmission, and distribution of gases that can contain aromatic hydrocarbons. 1.2 Fittings and connections This Standard covers all types of fittings and connections used in PA piping systems for gas services, including plastic-to-metal transition…

1 Scope 1.1 General This Standard specifies requirements for polyethylene of raised temperature (PE-RT) tubing systems that comprise tubing, with or without a barrier layer, and fittings. Tubing covered by this Standard is made in SDR 9. Systems are pressure rated at two temperatures: 1105 kPa at 23 °C and 690 kPa at 82 °C. Systems are intended for use in potable water distribution systems or…

1 Scope 1.1 General This Standard covers crosslinked polyethylene (PEX) pipe and fittings for use in gas mains and services, including gas gathering, gas transmission, and distribution of fuel gases. 1.2 Pipe This Standard covers PEX pipes in metric nominal sizes DN 16 to DN 1000 or nominal pipe sizes NPS-3 to NPS-54 that are a) pressure-rated using the hydrostatic design basis (HDB) rating…

1 Scope 1.1 General This Standard provides criteria for the analysis and design of new buildings and assessment of existing buildings to resist blast loading. Notes: 1) The main objective of this Standard is to reduce human casualties and damage to assets due to an air blast. 2) It should be recognized that the extent and severity of an explosion and resulting damage cannot be predicted…

This document describes the enterprise view (see ISO/TS 14812:2022, 3.1.4.3) of integrated mobility based on the role and responsibility models in the mobility as a service (MaaS) and mobility on demand (MOD) ecosystems as described in ISO/TR 4447. Other ISO documents (e.g. ISO 24014-1, ISO 17573-1 and ISO/TR 21724-1) have been reviewed in order to enhance and merge the MaaS and MOD role models.…

IEC 61098:2023 applies to contamination monitors that include warning assembles and meters used for the monitoring of radioactive contamination on the surface of personnel whether they be clothed or not. The document is applicable only to that type of equipment where the user stays at the monitor. This document is applicable to the monitoring of the whole body (including the head), hands and feet…

This document provides information about cast iron materials so that users and designers are in a better position to understand cast iron as a design material in its own right and to correctly specify cast iron for suitable applications. This document suggests what can be achieved, and what is not achievable when cast irons are specified as well as the reasons why. It is not designed to be a…

This document specifies a method for quantitative determination of 17 2,3,7,8-chlorine substituted dibenzo-p-dioxins and dibenzofurans and dioxin-like polychlorinated biphenyls in sludge, treated biowaste and soil using liquid column chromatographic clean-up methods and GC/HRMS. The analytes to be determined with this document are listed in Table 1. The limit of detection depends on the kind of…
