Introduction
This document is a type-C standard, according to as stated in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others stakeholder groups can be affected by the level of machinery safety achieved, with the means of
the document, by thosethe above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (for example,e.g. trade unions, organizations for people with special
needs);
— service providers, for example,e.g. for maintenance (small, medium and large enterprises);
— consumers (in the case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate inat the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or -B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 6085:2022(E)

Building construction machinery and equipment — Self-loading
mobile concrete mixers — Safety requirements and verification
1 Scope
This document specifies general safety requirements for self-loading mobile concrete mixers (here-
after referred to as “machines”) as defined in ISO 18650-1:2021, with rigid or articulated wheeled
chassis.
This document applies to machines which are designed for front or rear loading and are provided with
a swinging frame where the rotating drum and the self-loading equipment (lift arms and bucket) are
mounted on. Machines are also fitted with accessories such as water dosing means and a weighing
system.
This document deals with all significant hazards, hazardous situations and events relevant to the
machine when used as intended or under conditions of misuse reasonably foreseeable by the
manufacturer.
This document is not applicable to the following:
a) machines designed primarily for earth moving, such as loaders or dumpers (see applicable parts of
the ISO 20474 series);
b) truck mixers.
This document does not address hazards that can occur:
— during manufacture;
— when using machines on public roads, where specific local road regulations can apply;
— when operating in potentially explosive atmospheres.
This document is not applicable to machines manufactured before the date of its publication.

— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in the case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or -B
standards, the requirements of this type-C standard take precedence over the requirements of the
other standards for machines that have been designed and built according to the requirements of this
type-C standard.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 6085:2022(E)
Building construction machinery and equipment — Self-
loading mobile concrete mixers — Safety requirements
and verification
1 Scope
This document specifies general safety requirements for self-loading mobile concrete mixers (here-
after referred to as “machines”) as defined in ISO 18650-1:2021, with rigid or articulated wheeled
chassis.
This document applies to machines which are designed for front or rear loading and are provided with
a swinging frame where the rotating drum and the self-loading equipment (lift arms and bucket) are
mounted on. Machines are also fitted with accessories such as water dosing means and a weighing
system.
This document deals with all significant hazards, hazardous situations and events relevant to
the machine when used as intended or under conditions of misuse reasonably foreseeable by the
manufacturer.
This document is not applicable to the following:
a) machines designed primarily for earth moving, such as loaders or dumpers (see applicable parts of
the ISO 20474 series);
b) truck mixers.
This document does not address hazards that can occur:
— during manufacture;
— when using machines on public roads, where specific local road regulations can apply;
— when operating in potentially explosive atmospheres.
This document is not applicable to machines manufactured before the date of its publication.
