This document specifies two test methods (method A and method B) for determining the longitudinal tensile properties of glass-reinforced thermosetting plastics (GRP) pipes. The properties which can be determined are: — the longitudinal tensile strength, and — the percentage ultimate elongation. Method A uses, for the test piece(s), a longitudinal strip cut from a pipe. Method B uses a specified length of the full cross-section of the pipe. Method A is applicable to pipes with a nominal size of DN 50 or greater with circumferentially-wound filaments, with or without chopped glass and/or woven rovings and/or fillers, and to centrifugally-cast pipes. It is applicable to pipes with helically wound filaments with a nominal size of DN 200 or greater. Method B is applicable to all types of GRP pipe. It is usually used for pipes with a nominal size up to and including DN 150. Results from one method are not necessarily equal to the results derived from any of the alternative methods. However, all methods have equal validity. Annex A describes additional considerations for method B that have been found useful for the testing of thin-walled helically-wound pipes and can be used to supplement the basic text. NOTE This document does not address the determination of longitudinal tensile modulus. Due to the multi-layer construction of many GRP pipes, the accurate measurement of strain, necessary for modulus determination, can be very difficult. If it is desired to determine longitudinal modulus, see ISO 527-4 and/or ISO 527-5.

This document specifies a method to evaluate the capability of portable household air cleaners to reduce the concentration and viability of key experimentally generated bioaerosols in a specified chamber. Indoor air free of harmful microbes is important to the health of occupants. This is particularly relevant with regard to increased time spent indoors. Air cleaners are used to reduce the concentrations of microorganisms in indoor air. The efficiency of such air cleaners to reduce airborne microorganisms can be assessed in test chambers at controlled air temperature and relative air humidity. The test is applicable to portable air cleaners commonly used in single room spaces such as those based on mechanical filtration, ultraviolet (UV), ionizers, photocatalytic oxidation, and ozone generators in-unit technology. If the air cleaner does not claim to have the function of reducing microorganisms, this document may not be applicable unless it is being used to simply evaluate the performance. This document deals with measurement procedures regarding the reduction of the microbial contamination related to electrical air cleaner appliances for household and similar use. This document does not apply to appliances intended to be used in medical, veterinary, or pharmaceutical applications. This document does not address sanitization, disinfection, or sterilization measures. This document does not support, by itself any health-related claims or conclusions about prevention or treatment of a disease or health improvement. NOTE 1 IEC 63086-3-1 is created for household and similar electrical air cleaners and is not intended to conflict with or replace standards for commercial or industrial consumers. NOTE 2 In this document, we do not suggest performance test methods that measure the by-products of either the interaction between microbes or between the air cleaner and the microbes tested in this document. The formation of by-products is an important subject. The subject of measuring by-products is under study, and AHAM will address this in future documents. NOTE 3 This document does not apply to appliances intended for use in medical treatment locations, such as surgical suites, laboratories, medical treatment rooms, etc.

The efficiency of such air cleaners to reduce airborne microorganisms can be assessed in test chambers at controlled air temperature and relative air humidity.
The test is applicable to portable air cleaners commonly used in single room spaces such as those based on mechanical filtration, ultraviolet (UV), ionizers, photocatalytic oxidation, and ozone generators in-unit technology.
If the air cleaner does not claim to have the function of reducing microorganisms, this document may not be applicable unless it is being used to simply evaluate the performance.
This document deals with measurement procedures regarding the reduction of the microbial contamination related to electrical air cleaner appliances for household and similar use.
This document does not apply to appliances intended to be used in medical, veterinary, or pharmaceutical applications.
This document does not address sanitization, disinfection, or sterilization measures.
This document does not support, by itself any health-related claims or conclusions about prevention or treatment of a disease or health improvement.

This document specifies requirements and associated test methods for rubber materials used in gas installations, gas equipment and gas appliances in contact with 1st, 2nd and 3rd family combustible gases as classified in EN 437:2018, additionally LPG, bio methane and bio LPG, in the same quality, are covered. It also establishes a classification based on temperature range and hardness. This document is applicable to materials from which homogeneous seals and homogeneous or reinforced diaphragms are manufactured.
Since the dimensions and shape of the components differ from those of standard test pieces taken from sheet material as used for type testing of the rubber materials according to this document, tolerances have been made in the requirements specified by Annex A for the components with respect to those specified for standard test pieces.
The range of operating temperatures covered by this document is –40 °C to +150 °C.
For applications with potential condensation, this document is not applicable for silicon rubber, e.g. above 200 hPa (200 mbar) nominal pressure or at temperatures below 0 °C with 3rd family gases.

This clause of Part 1 is replaced by the following.
This part of IEC 60335 deals with the safety of electric heat pumps, including sanitary hot
water heat pumps, air conditioners, and dehumidifiers incorporating motor-compressors
and hydronic fan coils units, their maximum rated voltages being not more than 250 V for
single phase appliances and 600 V for all other appliances. Partial units are within the scope
of this International Standard.
Appliances not intended for normal household use but which nevertheless may be a source of
danger to the public, such as appliances intended to be used by laymen in shops, in light
industry and on farms, are within the scope of this standard.
The appliances referenced above may consist of one or more factory-made assemblies. If
provided in more than one assembly, the separate assemblies are to be used together, and
the requirements are based on the use of matched assemblies.
NOTE 101 A definition of ‘motor-compressor’ is given in IEC 60335-2-34, which includes the statement that the
term motor-compressor is used to designate either a hermetic motor-compressor or semi-hermetic motor-
compressor.
NOTE 102 Requirements for refrigerating safety are covered by ISO 5149-1, ISO 5149-2, and ISO 5149-3.
Requirements for containers intended for storage of the heated water included in sanitary hot water heat pumps
are, in addition, covered by IEC 60335-2-21.
This standard does not take into account refrigerants other than group A1, A2L, A2 and A3 as
defined by ISO 817 classification, A2L refrigerants are limited to those of a molar mass of
more than or equal to 42 kg/kmol based on WCF – Worst Case Formulation as specified in
ISO 817.
This standard specifies particular requirements for the use of flammable refrigerants. Unless
specifications are covered by this standard, including the annexes, requirements for
refrigerating safety are covered by ISO 5149.
The parts of ISO 5149 of particular concern to this standard are as follows:
• ISO 5149-1:2014, Refrigerating systems and heat pumps – Safety and environmental
requirements – Part 1: Definitions, classification and selection criteria.
• ISO 5149-2, Refrigerating systems and heat pumps – Safety and environmental
requirements – Part 2: Design, construction, testing, marking and documentation;
• ISO 5149-3:2014, Refrigerating systems and heat pumps – Safety and environmental
requirements – Part 3: Installation site.
Supplementary heaters, or a provision for their separate installation, are within the scope of
this standard, but only heaters which are designed as a part of the appliance package, the
controls being incorporated in the appliance.
NOTE 103 Attention is drawn to the fact that
• for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be
necessary;
• for appliances subjected to pressure, additional requirements may be necessary;
• in many countries, additional requirements are specified, for example, by the national health authorities
responsible for the protection of labour and the national authorities responsible for storage, transportation,
building constructions and installations.
