This consolidated version consists of the…
Rice — Determination of amylose content — Part 2: Spectrophotometric routine method without defattin...
This document specifies two simplified routine methods for the determination of the amylose mass fraction of milled rice, non-parboiled. The main difference between the two methods is the dispersion procedure: method A specifies hot dispersion, and method B specifies cold dispersion.
Both methods are applicable to rice with an amylose mass fraction higher than 5 %.
NOTE These methods describe…
Semiconductor devices - Mechanical and climatic test methods - Part 15: Resistance to soldering temp...
IEC 60749-15:2020 describes a test used to determine whether encapsulated solid state devices used for through-hole mounting can withstand the effects of the temperature to which they are subjected during soldering of their leads by using wave soldering. In order to establish a standard test procedure for the most reproducible methods, the solder dip method is used because of its more…
Safety of machinery - Electro-sensitive protective equipment - Part 1: General requirements and test...
IEC 61496-1:2020 specifies general requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons or part of a person as part of a safety-related system. Special attention is directed to functional and design requirements that ensure an appropriate safety-related performance is achieved. An ESPE can…
Surface mounting technology - Part 1: Standard method for the specification of surface mounting comp...
IEC 61760-1:2020 defines requirements for component specifications of electronic components that are intended for usage in surface mounting technology. To this end, it specifies a reference set of process conditions and related test conditions to be considered when compiling component specifications.
The objective of this document is to ensure that a wide variety of SMDs can be subjected to the…

Petroleum products — Determination of the ignition quality of diesel fuels — Cetane engine method
This document establishes the rating of diesel fuel oil in terms of an arbitrary scale of cetane numbers (CNs) using a standard single cylinder, four-stroke cycle, variable compression ratio, indirect injected diesel engine. The CN provides a measure of the ignition characteristics of diesel fuel oil in compression ignition engines. The CN is determined at constant speed in a pre-combustion…
Surface cleaning appliances - Part 4: Cordless dry vacuum cleaners for household or similar use - Me...
IEC 62885-4:2020 is applicable to measurements of the performance of cordless dry vacuum cleaners for household use or under conditions similar to those in households. The results obtained under this document are intended to be comparable to the results obtained under IEC 62885-2 for mains-connected vacuums.
The purpose of this document is to specify essential performance characteristics of…
