This International Standard is applicable to dry-cleaning robots for household use or under conditions similar to those in households.

 

The purpose of this standard is to specify the essential performance characteristics of dry- cleaning robots which are of interest to users and to describe methods for measuring these characteristics.

 

This standard is neither concerned with safety requirements nor with performance requirements.

This part of IEC 60749 provides a means of assessing the resistance to soldering heat of semiconductors packaged as plastic encapsulated surface mount devices (SMDs). This test is destructive.

This part of IEC 60749 establishes a standard procedure for determining the preconditioning of non-hermetic surface mount devices (SMDs) prior to reliability testing.

The test method defines the preconditioning flow for non-hermetic solid-state SMDs representative of a typical industry multiple solder reflow operation.

These SMDs are subjected to the appropriate preconditioning sequence described in this standard prior to being submitted to specific in-house reliability testing (qualification and/or reliability monitoring) in order to evaluate long term reliability (impacted by soldering stress).

NOTE 1 Correlation of moisture-induced stress sensitivity conditions (or moisture sensitivity levels (MSL)) in accordance with IEC 60749-20 and this specification and actual reflow conditions used are dependent upon identical temperature measurement by both the semiconductor manufacturer and the board assembler. Therefore, it is recommended that the temperature at the top of the package on the hottest moisture sensitive SMD during assembly be monitored to ensure that it does not exceed the temperature at which the components are evaluated.

NOTE 2  For the purpose of this standard, SMD is restricted to include only plastic-encapsulated SMDs and other packages made with moisture-permeable materials.

This document gives the rules of definition and interpretation of general specifications defined according to ISO 8015 (general tolerancing) applicable on the whole workpiece.

The general specifications can be applied to integral surfaces only, i.e. integral lines are excluded.

The general geometrical and dimensional specifications defined in this document applies to the following:

—    for dimensional specifications:

—    for features of size:

—    linear size (±) (according to ISO 14405‑1);

—    angular size (±)(according to ISO 14405‑3);

—    for geometrical specifications:

—    for integral features:

—    geometrical specifications with the characteristic surface profile (⌓).

This International Standard specifies a method of determining the particle size distribution of metallic powders by dry sieving into size fractions.

The method is applicable to dry, unlubricated metallic powders, but not applicable to powders in which the morphology differs markedly from being equiaxial, for example flake-type powders.

The method is not applicable to metallic powders having a particle size wholly or mostly under 44 µm.

This part of ISO 12004 specifies the testing conditions to be used when constructing a forming-limit curve (FLC) at ambient temperature and using linear strain paths. The material considered is flat, metallic and of thickness between 0,3 mm and 4 mm.

NOTE          The limitation in thickness of up to 4 mm is proposed, giving a maximum allowable thickness to the punch diameter ratio.

For steel sheet, a maximum thickness of 2,5 mm is recommended.

This International Standard specifies three methods (two titrimetric and one potentiometric) for the determination of the acidity in animal and vegetable fats and oils, hereinafter referred to as fats. The acidity is expressed preferably as acid value, or alternatively as acidity calculated conventionally.

This International Standard is applicable to refined and crude vegetable or animal fats and oils, soap stock fatty acids or technical fatty acids. The methods are not applicable to waxes.

Since the methods are completely non-specific, they cannot be used to differentiate between mineral acids, free fatty acids, and other organic acids. The acid value, therefore, also includes any mineral acids that may be present.

Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of ISO 660.
