Electromagnetic compatibility (EMC) — Part 4-18: Testing and measurement techniques — Damped oscilla...
1 Scope and object
This part of IEC 61000-4 relates to the immunity requirements and test methods for electrical
and electronic equipment, under operational conditions, with regard to:
a) repetitive damped oscillatory waves occurring mainly in power, control and signal cables
installed in high voltage and medium voltage (HV/MV) substations;
b) repetitive damped oscillatory waves occurring…
1.1 General
This Standard specifies requirements for
a) mortar for use in bedding, jointing, and bonding of masonry units; and
b) grout for use in filling core, cell, or cavity space in unit masonry construction.
Notes:
1) The term “unit masonry” refers to masonry construction using clay (shale), calcium silicate (sand-lime), or
concrete masonry units, with individual units not more than 200 mm…

Soils – Determination of the Water Content-Dry Density Relation – Standard Compaction Effort Test(60...
1 PURPOSE AND SCOPE
This standard specifies the test method to determine the relation between the water content and the
dry density of soil and soil aggregates mixes when they are compacted in a standard mould by a
2,495 kg rammer dropped from a height of 305 mm. Three methods are used to determine this
relation (see Chapter 5).
NOTE — The laboratory compaction test methods described in this…
Soils – Determination of the Water Content-Dry Density Relation – Modified Compaction Effort Test(27...
1 PURPOSE AND SCOPE
This standard specifies the test method to determine the relation between the water content and the
dry density of soil and soil aggregates mixes when they are compacted in a standard mould by a
4,536 kg rammers dropped from a height of 457 mm. Three methods are used to determine this
relation (see Chapter 5).
NOTE — The laboratory compaction test methods described in…
Rubber, vulcanized or thermoplastic — Determination of ageing characteristics by measurement of stre...
ISO 6914:2013 describes three methods for the measurement of the change of stress in a test piece at a given elongation for the purpose of determining the ageing characteristics of a rubber.
Method A is intended for measurement under continuous strain conditions.
Method B is the preferred method for measurement under intermittent strain conditions.
In the case of both methods A and B, a…
Paints and varnishes — Methods of exposure to laboratory light sources — Part 3: Fluorescent UV lamp...
ISO 16474-3:2013 specifies methods for exposing coatings to fluorescent UV lamps, heat and water in apparatus designed to reproduce the weathering effects that occur when materials are exposed in actual end-use environments to daylight, or to daylight through window glass.
The coatings are exposed to different types of fluorescent UV lamps under controlled environmental conditions (temperature,…
Paints and varnishes — Methods of exposure to laboratory light sources — Part 1: General guidance
ISO 16474-1:2013 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 paints and varnishes to laboratory light sources. Information about such performance requirements is required only by producers of artificial…
Paints and varnishes — Methods of exposure to laboratory light sources — Part 2: Xenon-arc lamps
ISO 16474-2:2013 specifies methods for exposing specimens to xenon-arc light in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end-use environments to daylight or to daylight filtered through window glass.
The specimens are exposed to filtered xenon-arc light under controlled conditions (temperature, humidity and/or wetting). Various…
Paints and varnishes — Methods of exposure to laboratory light sources — Part 4: Open-flame carbon-a...
ISO 16474-4:2013 specifies methods for exposing specimens to open-flame carbon-arc lamps in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end-use environments to daylight or to daylight filtered through window glass.
The specimens are exposed to filtered open-flame carbon-arc light under controlled conditions (temperature, humidity…
