This International Standard specifies principles for the design and selection – independent of the nature of the energy source – of interlocking devices associated with guards.
It also provides requirements specifically intended for electrical interlocking devices.
This International Standard covers the parts of guards which actuate interlocking devices.
NOTE Requirements for guards are given in ISO 14120. The processing of the signal from the interlocking device to stop and immobilize the machine is dealt with in ISO 13849-1.
This International standard is intended to provide measures to minimize defeat of interlocking devices in a reasonably foreseeable manner.
This document specifies methods for reducing combined samples to laboratory samples and laboratory samples to sub-samples and general analysis samples. The methods described in this document may be used for sample preparation, for example, when the samples are to be tested for bulk density, biomass determination, durability, particle size distribution, moisture content, ash content, ash melting behaviour, calorific value, chemical composition, and impurities. The methods are not intended to be applied to the very large samples required for the testing of bridging properties.
This document specifies a method to determine the amounts of polycyclic aromatic hydrocarbons (PAH) in footwear and footwear components.
NOTE A list of relevant materials can be found in ISO/TR 16178, Table 1.
This document specifies requirements and recommendations for using simultaneous interpreting delivery platforms at communicative events where the interpreters are not at the same venue as participants, speakers and signers.
In cases where interpreters are at the same venue as participants, speakers and signers, ISO 20109 shall apply to ensure a high level working environment and the acoustic performance of the overall conference system.
In conjunction with ISO 20108, this document provides requirements and recommendations for ensuring the quality of sound and images and their transmission to interpreters and from interpreters to participants, and for the configuration of the interpreter’s working environment.
This document specifies a method to determine the amounts of dimethylformamide (DMF) in footwear and footwear components containing polyurethane (PU) coated material.
NOTE 1 In footwear industry, when PU is injected (reaction moulded), this process does not need the use of DMF. For PU coated material, the use of DMF is possible.
NOTE 2 Several abbreviations can be used for dimethylformamide DMF, DMFa, DMFo. This document recommends to use DMF.
CEN ISO/TR 16178, table 1 defines which materials are concerned by this determination.
This document is for passive infrared detectors installed in buildings and provides for security grades 1 to 4 (see EN 50131 1), specific or non-specific wired or wire-free detectors, and uses environmental classes I to IV (see EN 50130 5). This document does not include requirements for detectors intended for use outdoors.
The purpose of the detector is to detect the broad spectrum infrared radiation emitted by an intruder, to analyse the resulting signals and to provide the necessary range of signals or messages to be used by the rest of the intrusion alarm system.
The grade-dependent requirements of this document apply and it is essential that a detector fulfils all the requirements of the specified grade.
Functions additional to the mandatory functions specified in this document can be included in the detector, providing they do not influence the correct operation of the mandatory functions.
Requirements for system interconnections are not included in this document.
This part of ISO 12312 is applicable to all afocal (plano power) sunglasses and clip-ons for general use, including road use and driving, intended for protection against solar radiation.
Information on the use of sunglass filters is given in Annex A. Requirements for unmounted filters used as replacement or alternative filters are given in Annex C.
This part of ISO 12312 is not applicable to:
a) eyewear for protection against radiation from artificial light sources, such as those used in solaria;
b) eye protectors intended for specific sports (e.g. ski goggles or other types);
c) sunglasses that have been medically prescribed for attenuating solar radiation;
d) products intended for direct observation of the sun, such as for viewing a partial or annular solar eclipse;
e) products intended for occupational eye protection.
This document specifies requirements for the qualification and certification of personnel who perform industrial non-destructive testing (NDT) in the following methods.
a) acoustic emission testing;
b) eddy current testing;
c) thermographic testing;
d) leak testing (hydraulic pressure tests excluded);
e) magnetic testing;
f) penetrant testing;
g) radiographic testing;
h) strain gauge testing;
i) ultrasonic testing;
j) visual testing (direct unaided visual tests and visual tests carried out during the application of another NDT method are excluded).
The system specified in this document is also applicable to other NDT methods or to NDT techniques within an established NDT method, provided a comprehensive scheme of certification exists and the NDT method or NDT technique is covered by International, regional or national standards or the NDT method or NDT technique has been demonstrated to be effective to the satisfaction of the certification body.
NOTE 1 The term "industrial" implies the exclusion of applications in the field of medicine.
NOTE 2 CEN/TR 14748 provides guidance for methodology for qualification of NDT systems.
NOTE 3 This document specifies requirements for what are, in effect, third party conformity assessment schemes. These requirements do not directly apply to conformity assessment by second or first parties, but relevant parts of this document can be referred to in such arrangements.
NOTE 4 The term “direct unaided visual testing” implies where there is an uninterrupted optical path from the observer’s eye to the test area and the observer uses no tools or devices (e.g. mirror, lens, endoscope, fibre optic, etc…).
NOTE 5 Calculations of strain based on other NDT methods are excluded.
This document specifies methods for the determination of the liquid and plastic limits of a soil. These comprise two of the Atterberg limits for soils.
The liquid limit is the water content at which a soil changes from the liquid to the plastic state.
This document describes the determination of the liquid limit of a specimen of natural soil, or of a specimen of soil from which material larger than about 0,4 mm has been removed. This document describes two methods: the fall cone method and the Casagrande method.
NOTE The fall cone method in this document should not be confused with that of ISO 17892‑6.
The plastic limit of a soil is the water content at which a soil ceases to be plastic when dried further.
The determination of the plastic limit is normally made in conjunction with the determination of the liquid limit. It is recognized that the results of the test are subject to the judgement of the operator, and that some variability in results will occur.
This document identifies requirements and gives recommendations for the performance, dimensional and functional interchangeability, design, materials, testing, inspection, welding, marking, handling, storing, shipment, and purchasing of wellhead and tree equipment for use in the petroleum and natural gas industries.
This document does not apply to field use or field testing. This document also does not apply to repair of wellhead and tree equipment except for weld repair in conjunction with manufacturing. Tools used for installation and service (e.g. running tools, test tools, wash tools, wear bushings, and lubricators) are outside the scope of this document.
This document supplements API Spec 6A, 21st edition, the requirements of which are applicable with the exceptions specified in this document.
This document specifies the methodology to determine if a laboratory is in control in the execution of a standard test method. By using statistical control charts and following this document the 'in-statistical-control' status is established and validated. In-statistical-control means the test results produced by the lab on control samples are reasonably consistent with expectation over time; with random variation scattered around a stable expected centre due to common causes only
This document explicitly defines ‘site precision’ conditions as single apparatus, multi-operators, over a long time horizon. It specifies control charts that are most appropriate for ISO TC28 test methods where the dominant common cause variation is associated with the long term, multiple operator conditions as described by "site precision" conditions. The control charts specified for determination of in-statistical-control are: Individual (I), Moving Range of 2 (MR2), Exponentially Weighted Moving Average (EWMA), and zone-based run rules (commonly known as Western Electric (WE)run rules.
The procedures in this document have been designed specifically for petroleum and petroleum related products, which are normally considered as homogeneous and for test methods which show normality in obtaining their results. However, the procedures described in this document can also be applied to other types of homogeneous products and test methods.
This document specifies minimum requirements for self-contained closed-circuit breathing RPDs for escape (short: oxygen escape RPD)
