Acoustics -- Laboratory tests on noise emission from appliances and equipment used in water supply installations -- Part 3: Mounting and operating conditions for in-line valves and appliances
ISO 3822-3:2018 specifies the mounting and operating conditions to be used for in-line valves and appliances which control the flow, pressure or temperature of the water in water supply installations, when measuring noise emission resulting from water flow. ISO 3822-3:2018 is applicable to in-line valves and appliances of maximum nominal size DN 32 and to systems in which the maximum water flow rate does not exceed 1,6 l/s. NOTE See ISO 6708; DN is the symbol for "nominal size". The number of the nominal size is loosely related to the inside diameter (in millimetres) of the in-tine valves and appliances. The procedures described are for general use for all types of in-line valves of conventional design.

Toote geomeetrilised spetsifikatsioonid (GPS). Töödeldavate detailide ja mõõtevahendite kontrollimine mõõtmete alusel. Osa 1: Spetsifikatsioonile vastavuse või mittevastavuse tõendamise reeglid
See osa standardist ISO 14253 kehtestab reeglid, et määratleda konkreetse töödeldava detaili (või detailide kogumi) karakteristiku vastavust või mittevastavust antud tolerantsile või maksimaalselt lubatava mõõtehälbe piiridele mõõtevahendite korral, võttes arvesse mõõtemääramatust. Need reeglid erinevad üksikute töödeldavate detailide tolerantside ja detailide kogumite tolerantside korral. Standard esitab ka reeglid, kuidas lahendada olukordi, milles ühest otsust (spetsifikatsioonile vastavuse või mittevastavuse kohta) ei ole võimalik teha, st kui mõõtetulemus jääb spetsifikatsiooni piire ümbritsevasse määramatuse piirkonda (vt jaotis 3.23). See osa standardist ISO 14253 rakendub üldistele, st ISO/TC 213 koostatud GPS-standardites määratletud spetsifikatsioonidele (vt ISO/TR 14638), mis hõlmavad: — töödeldava detaili/detailide kogumi spetsifikatsioone (harilikult esitatud kui ülemine tolerantsipiir või alumine tolerantsipiir või mõlemad), ja — mõõtevahendi spetsifikatsioone (harilikult esitatud kui maksimaalselt lubatavad mõõtehälbed). See osa standardist ISO 14253 rakendub ainult suuruse väärtusarvuga väljendatud karakteristikutele.
This part of ISO 14253 establishes the rules for determining the conformity or nonconformity with a given tolerance for a characteristic of a workpiece (or a population of workpieces) or limits of maximum permissible errors for a metrological characteristic of a measuring equipment, taking into account the measurement uncertainty. These rules are different for tolerances to individual workpieces and tolerances to workpiece populations. It also gives rules on how to deal with cases where a clear decision (conformity or nonconformity with specification) cannot be taken, i.e. when the measurement result falls within the uncertainty range (see 3.23) that exists around the specification limits. This part of ISO 14253 applies to specifications defined in general GPS standards (see ISO/TR 14638), i.e. standards prepared by ISO/TC 213, including: — workpiece/population of workpieces specifications (usually given as an upper tolerance limit or a lower tolerance limit or both), and; — measuring equipment specifications (usually given as maximum permissible errors). This part of ISO 14253 only applies for characteristics expressed as numerical quantity values. This part of ISO 14253 does not apply to inspection using limit gauges. Inspection with limit gauges is covered by ISO 1938-1.

Liquid pumps and pump units - Noise test code - Grades 2 and 3 of accuracy (ISO/DIS 20361:2018)
This International Standard specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration, and verification of the airborne noise emission of liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test. Noise emission characteristics include emission sound pressure levels at specified positions and the sound power level. The determination of these quantities is necessary for — declaring the noise emission values, and — purpose of noise control at source at the design stage. The determination of these quantities is also necessary for comparing the noise emitted by liquid pumps on the market. The use of this International Standard ensures the reproducibility of the determination of the airborne noise-emission characteristics within specified limits determined by the grade of accuracy of the basic airborne noise measurement method used. Noise measurement methods according to this International Standard are engineering methods (grade 2) and survey methods (grade 3). This International Standard does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps. NOTE This International Standard is specified in EN 809+A1 for noise measurements of the Pump (or Pump Unit).
