1.1 This part of ISO 527 specifies the general principles for determining the tensile properties of plastics and plastic composites under defined conditions. Several different types of test specimen are defined to suit different types of material which are detailed in subsequent parts of ISO 527.

1.2 The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus and other aspects of the tensile stress/strain relationship under the conditions defined.

1.3 The methods are selectively suitable for use with the following materials:

— rigid and semi-rigid (see 3.12 and 3.13, respectively) moulding, extrusion and cast thermoplastic materials, including filled and reinforced compounds in addition to unfilled types; rigid and semi-rigid thermoplastics sheets and films;

— rigid and semi-rigid thermosetting moulding materials, including filled and reinforced compounds; rigid and semi-rigid thermosetting sheets, including laminates;

— fibre-reinforced thermosets and thermoplastic composites incorporating unidirectional or non-unidirectional reinforcements, such as mat, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforcement, rovings and milled fibres; sheet made from pre-impregnated materials (prepregs),

— thermotropic liquid crystal polymers.

The methods are not normally suitable for use with rigid cellular materials, for which ISO 1926 is used, or for sandwich structures containing cellular materials.

This International Standard specifies test methods and the environmental conditions for evaluating the performance of reciprocating positive displacement pumps and centrifugal pumps designed for crop protection equipment.

This standard is applicable to define the performance of the pump when stand alone or installed on a sprayer.

Some of the tests indicated in this document are suited only for specific pump types.

It is not applicable to pesticide metering pumps for injection systems.

The Standard specifies test conditions and test procedures for determining the performance characteristics of air source heat pump water heaters for space heating with electrically driven compressors with or without supplementary heater. The purpose of this standard is to rate performance of the heat pump water heaters for space heating with no operation of any supplementary heater In the case of heat pump water heaters for space heating consisting of several parts with refrigerant or water connections, this standard applies only to those designed and supplied as a complete package.

NOTE Testing procedures for simultaneous operation for hot water supply and space heating are not treated in this standard. Simultaneous means that hot water supply and space heating generation occur at the same time and may interact.

This document provides requirements to govern the application of explicit algebraic equation sets to the calculation of fire phenomena. This document is an implementation of the general requirements provided in ISO 16730-1 for the case of fire dynamics calculations involving sets of explicit algebraic equations.

This document is arranged in the form of a template, where specific information relevant to algebraic equations are provided to satisfy the following types of general requirements:

a) Requirements governing description of physical phenomena;

b) Requirements governing calculation process;

c) Requirements governing limitations;

d) Requirements governing input parameters;

e) Requirements governing domain of applicability.

This part of ISO 16000 concerns a method for the determination of primary, secondary and tertiary aliphatic and aromatic amines in indoor air using accumulated sampling and high-performance liquid-chromatography (HPLC) coupled with tandem mass spectrometry (MS-MS) or high resolution mass spectrometry (HRMS). This standard specifies the sampling procedure for determining the mass concentration of amines as mean values by sampling the amines on phosphoric acid impregnated filters. The analytical procedure of the measurement method is covered by ISO 16000-39.

Measurements, performed with samplers containing phosphoric acid-impregnated inert supporting material and operating at specified flow rates for specified sampling periods are described in this document. Requirements regarding sample volume are defined.

The range of application of this International Standard concerning the concentrations of amines in indoor air depends on the linear range of the calibration line and hence on the gas sample volume (here: from 5 l up to 100 l), the eluate volume (from 1 ml up to 5 ml), the injection volume (from 1 μl up to 10 μl) and the sensitivity of the analytical equipment (e.g. linear range from 2 pg up to 2 ng amine). The range of application can be expected to be from approximately 0,002 μg/m3 (100 l sample) up to 2 000 μg/m3 (5 l sample) for a common analytical equipment (e.g. Waters „TQ-D") for the majority of the amines listed in Annex A. The analysis of derivatives of ethanolamine is usually about 10 times more sensitive and the analysis of short-chained aliphatic amines is usually about 10 times less sensitive than the analysis of an average amine.

Although primarily intended for the measurement of amines listed in Annex A, this International Standard may be used also for the measurement of other amines in indoor air.

This International Standard describes procedures for the fabrication and gives requirements for the use of glass tubes containing impregnated filters out of phosphoric acid-impregnated glass wool as samplers, but does not exclude other samplers with proven equal or improved properties. This Standard also gives procedures for the demonstration of equivalence of other sampler types or methods.

This International Standard does not cover the determination of amines in other media like water or soil. Furthermore, it does not cover the determination of isocyanates in indoor air as corresponding amines (covered by ISO 17734 Part 1 and 2). Also quaternary amines are not included in this International Standard.

ISO 16000 Part 39 – in combination with ISO 16000 Part 38 – specifies the measurement method for determining the mass concentration of primary, secondary and tertiary aliphatic and aromatic amines in indoor air using accumulated sampling and high-performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS-MS) or high resolution mass spectrometry (HRMS). The analytical procedure is covered by this standard. The sampling procedure and the manufacturing of the samplers are covered by ISO 16000 Part 38.

ISO 16000-39 mentions specifications for the chromatography and the mass spectroscopy for the amines. Measurement results are expressed in μg/m3.

Although primarily intended for the measurement of amines listed in Table A.1 in Annex A of this International Standard, it may be used also for the measurement of other amines in indoor air. This International Standard gives instructions and describes procedures for the inclusion of other amines.

The range of application of this International Standard concerning the concentrations of amines in indoor air depends on the linear range of the calibration line and hence on the gas sample volume (here: from 5 l up to 100 l), the eluate volume (from 1 ml up to 5 ml), the injection volume (from 1 μl up to 10 μl) and the sensitivity of the analytical equipment (e.g. linear range from 2 pg up to 2 ng amine). The range of application can be expected to be from approximately 0,002 μg/m3 (100 l sample) up to 2 000 μg/m3 (5 l sample) for a common analytical equipment (e.g. Waters „TQ-D") for the majority of the amines listed in Table A.1 in Annex A. The analysis of derivatives of ethanolamine is usually about 10 times more sensitive and the analysis of short-chained aliphatic amines is usually about 10 times less sensitive than the analysis of an average amine.

This International Standard can be used also for the determination of amines in water if the detection limit is sufficient.

This International Standard does not cover the determination of isocyanates in indoor air (nor in water samples) as corresponding amines (covered by ISO 17734 Part 1 and 2).
