Specifies values of the physical properties of annealed copper and how the conductivity of commercial annealed copper can be calculated and expressed as a percentage of standard annealed copper.
Cranes — Proof of competence of steel structures — Part 1: General
ISO 20332-1:2008 sets forth general conditions, requirements, methods and parameter values for performing proof-of-competence determinations of the steel structures of cranes based upon the limit state method. It is intended to be used together with the loads and load combinations of the applicable parts of ISO 8686.
ISO 20332-1:2008 is general and covers cranes of all types. Other International…
Adhesives — Test methods for the selection of adhesives for indoor wood products
ISO 26842:2008 gives guidelines for the selection, by means of durability tests, of adhesives for use in wood products placed in indoor environments.
A series of exposure cycles at various temperatures and humidities is provided to verify that the adhesive selected, or a product bonded with the adhesive, meets the necessary durability requirements.
This International Standard is intended to help…
Oilseeds — Application of near infrared spectrometry
This International Standard gives a procedure for the prediction by near infrared spectroscopy of constituents such as moisture, fat and protein and some minor parameters such as total glucosinolates in oilseeds and oilseeds meals. The determinations are based on spectrometric measurement in the near infrared spectral region.
Tyre abrasion rate measurement methods — Part 1: Outdoor test method by using vehicles on road
This international standard (part 1 or part 2) specifies the method for measuring tread abrasion mass loss of a candidate tyre per unit distance travelled, under loaded conditions, by using vehicles on road (part 1) or an external drum tester (part 2).
Each test method specified in Part 1 and Part 2 measures abrasion performance of a candidate tyre on the running mode representing vehicle driving…
Medical electrical equipment — Part 2-31: Particular requirements for the basic safety and essential...
IEC 60601-2-31:2020 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of EXTERNAL PACEMAKERS powered by an INTERNAL ELECTRICAL POWER SOURCE, hereafter referred to as ME EQUIPMENT. This document applies to PATIENT CABLES as defined in 201.3.209, but does not apply to LEADS as defined in 201.3.206. HAZARDS inherent in the intended physiological function of ME EQUIPMENT within the scope of this…
An adhesion evaluation method for microcircuits on PCB (Printed Circuit Board) by scratch test
This document describes a method for measuring adhesion strength between microcircuits and substrates by scratching with the wedged-shape diamond stylus. Using the traditional adhesion test, it is difficult to evaluate the adhesion strength of the microcircuits with a narrower scratching stylus.
During the test, applying stylus force is constant or progressive and normal to the surface. This…
