Ergonomics principles in the design of work systems (ISO 6385:2016, IDT) (First revision)
MS ISO 6385:2020
Status : 1st Revision
Format : PDF

This International Standard establishes the fundamental principles of ergonomics as basic guidelines
for the design of work systems and defines relevant basic terms. It describes an integrated a ....Read more pproach
to the design of work systems, where ergonomists will cooperate with others involved in the design.
with attention to the human, the social and the technical requirements in a balanced manner during the
design process.
Users of this International Standard will include executives, managers, workers (and their
representatives, when appropriate) and professionals, such as ergonomists, project managers and
designers who are involved in the design or redesign of work systems. Those who use this International
Standard can find a general knowledge of ergonomics (human factors),engineering, design, quality and
project management helpful.
The term "work system" in this International Standard is used to indicate a large variety of working
situations, including permanent and flexible work places. The intention of this International Standard is
to assist in the improvement, redesign or change of work systems. Work systems involve combinations
of workers and equipment, within a given space and environment, and the interactions between these
components within a work organization. Work systems vary in complexity and characteristics for
example, the use of temporary work systems. Some examples of work systems in different areas are the
following:
- Production, eg: machine operator and machine, worker and assembly line.
- Transportation, eg: driver and car or lorry, personnel in an airport.
- Support, e.g. maintenance technician with work equipment;
- Commercial, eg: office worker with workstation, mobile worker with a tablet computer, cook in a
restaurant kitchen;
- Other areas like health care, teaching and training.
The observance of ergonomic principles applies to all phases throughout the life cycle of the work system
from conception through development, realization and implementation, utilization, maintenance and
support to decommissioning.
The systems approach in this International Standard gives guidance to the users of this International
Standard in existing and new situations.
The definitions and ergonomic principles specified in this International Standard apply to the design
of optimal working conditions with regard to human well being, safety and health, including the
development of existing skills and the acquisition of new ones, while taking into account technological
and economic effectiveness and efficiency.
The principles in this International Standard are applicable to many other human activities, eg: in the
design of products for domestic and leisure activities. A more general description of the principles in
this International Standard can be found in ISO 26800.
NOTE : This International Standard is considered to be the core ergonomic standard for work systems from
which many others on specific issues are derived.
Note : Although elements of the system can be the same, this International Standard is not intended to be
applied to systems used in a non-work context, (eg: the use of a vehicle for private purposes). Close

Rubber, vulcanized orthermoplastic - Determination of compression set - ICS: 83.060 © Copyright 2020 DEPARTMENT OF STANDARDS MALAYSIA Descriptors: rubber, vulcanized rubber, thermoplastic rubber, compression set, low temperature Part 2: At low temperatures (Second revision) (ISO 815-2:2019, IDT)
MS ISO 815-2:2020
Status : 2nd Revision
Format : PDF

This document specifies two methods for the determination of the compression set characteristics of vulcanized and thermoplastic rubbers at low temperatures.
Method 1 derives from the methodolog ....Read more y used in ISO 815-1. Method 2 uses a specified testing device, allowing to measure and record the test piece thickness during recovery. Due to the load applied during recovery in method 2, no correlation can be established between the results given by both methods.
NOTE When rubber is held under compression, physical or chemical changes that prevent the rubber returning to its original dimensions after release of the deforming force can occur. The result is a set, where the magnitude of which depends on the time and temperature of compression as well as on the time, temperature, and conditions of recovery. At low temperatures, changes resulting from the effects of glass hardening or crystallization become predominant and, since these effects are reversed by raising the temperature, therefore, the measurements are always taken at the test temperature.

Rubber, vulcanized or thermoplastic - Determination of compression set - Part 1: At ambient or elevated temperatures Descriptors: rubber, vulcanized, thermoplastic, determination, temperature, compression set (Second revision) (ISO 815-1:2019, IDT)
MS ISO 815-1:2020
Status : 2nd Revision
Format : PDF

This document specifies methods for the determination of the compression set characteristics of
vulcanized and thermoplastic rubbers at ambient (one method) or elevated temperatures (three
....Read more methods, A, B, and C, depending on the way the test piece is released at the end of the test).
The methods are intended to measure the ability of rubbers of hardness within the range 10 IRHD to
95 IRHD to retain their elastic properties at specified temperatures after prolonged compression at
constant strain (normally 25 %) under one of the alternative sets of conditions described. For rubber of
nominal hardness 80 IRHD and above, a lower compression strain is used: 15 % for a nominal hardness
from 80 IRHD to 89 IRHD and 10 % for a nominal hardness from 90 IRHD to 95 IRHD.
NOTE 1 When rubber is held under compression, physical or chemical changes that prevent the rubber
returning to its original dimensions after release of the deforming force can occur. The result is a set, the
magnitude of which depends on the time and temperature of compression as well as on the time, temperature,
and conditions of recovery. At elevated temperatures, chemical changes become increasingly more important
and lead to a permanent set.
NOTE 2 Short-time compression set tests, typically for 24 h, at elevated temperatures are commonly used as
a measure of the state of cure, a means of material classification, and a specification to ensure the quality of a
compound. Longer tests, typically for 1 000 h, at elevated temperatures take account of the effect of ageing and
are often used to predict service performance, including that of sealing materials. Short-time tests at ambient
temperature show mainly the effect of physical changes (re-orientation of the molecular chains and the fillers). Close
