Electroacoustics - Measurement microphones - Part 5: Methods for pressure calibration of working sta...
IEC 61094-5:2016 is applicable to working standard microphones with removable protection grids meeting the requirements of IEC 61094-4 and to laboratory standard microphones meeting the requirements of IEC 61094-1. This part of IEC 61094 describes methods of determining the pressure sensitivity by comparison with either a laboratory standard microphone or another working standard microphone with…
Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-0...
IEC 61010-2-020:2016 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 61010-2-020:2016 is applicable to electrically powered LABORATORY CENTRIFUGES. This third edition cancels and…
Testing methods for pervious concrete — Part 1: Infiltration rate
ISO 17785-1:2016 specifies the procedure for testing the infiltration rate of hardened pervious concrete pavement specimens in the laboratory. It is not a method for measuring the permeability of pervious concrete. The specimens can either be prepared in the laboratory or cored from field placements, but not representing field conditions. This part of ISO 17785 also specifies procedures to make…
Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-0...
IEC 61010-2-020:2016 is applicable to electrically powered LABORATORY CENTRIFUGES. This third edition cancels and replaces the second edition published in 2006. It constitutes a technical revision and includes the following significant changes from the second edition:
a) This Part 2 is established on the basis of the third edition (2010) of IEC 61010-1. The changes listed in its foreword affect…
Optics and photonics — Environmental test methods — Part 9: Solar radiation and weathering
ISO 9022-9:2016 specifies the methods relating to the environmental tests of optical instruments including additional assemblies from other fields (e.g. mechanical, chemical and electronic devices), under equivalent conditions, for their ability to resist the effects of simulated solar radiation or laboratory weathering, which is a combination of simulated solar radiation, heat, and moisture. It…
Rubber, vulcanized or thermoplastic — Determination of adhesion to a rigid substrate — 90 degree pee...
ISO 813:2016 specifies a method for the determination of the adhesive strength of a vulcanized or thermoplastic rubber bonded to a rigid substrate, using a test piece comprising a strip of rubber bonded to a single plate of rigid material. The test is carried out at a peel angle of 90°.
The method is applicable primarily to test pieces prepared in the laboratory under standard conditions, such as…
Dentistry — Nominal diameters and designation code numbers for rotary instruments
ISO 2157:2016 specifies the nominal diameters of the working parts of dental rotary instruments, for example burs, laboratory burs, grinding instruments, diamond instruments, mandrels and the corresponding designation.
Excluded are the diameters of endodontic instruments and scaler tips.
Dentistry — Laboratory cutters — Part 1: Steel laboratory cutters
ISO 7787-1:2016 specifies dimensional and other requirements for the nine most commonly used steel cutters which are predominantly used in the dental laboratory.
Other characteristics of laboratory cutters, for example, spiralled blades or cross-cut, are not covered by this part of ISO 7787.
NOTE These cutters are also used in podiatry.
Plastics — Methods of exposure to laboratory light sources — Part 1: General guidance
ISO 4892-1:2016 provides information and general guidance relevant to the selection and operation of the methods of exposure described in detail in subsequent parts. It also describes general performance requirements for devices used for exposing plastics to laboratory light sources. Information regarding performance requirements is for producers of artificial accelerated weathering or artificial…
Fertilizers and liming materials — Sampling and sample preparation — Part 2: Sample preparation
ISO 14820-2:2016 specifies methods for the reduction and preparation of samples of fertilizers and liming materials and sets out the requirements for sample preparation reports. It also specifies methods for the preparation of test samples and test portions from laboratory samples of fertilizer for subsequent chemical or physical analysis. It does not cover the preparation of samples for certain…
