Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 12576-2 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the

built environment, Subcommittee SC 3, Thermal insulation products.

ISO 12576 consists of the following parts, under the general title Thermal insulation products — Conformity

control systems:
⎯ Part 1: Factory-made products
⎯ Part 2: In-situ products

4 Conformity systems, their elements and recommended application of the systems
4.1 General

In this specification, the following three systems for attestation of conformity are described:

⎯ system A: qualified contractor's self-declaration of conformity in accordance with ISO 17050-1, based on

the installer's documented installation procedures and internal quality control and initial type testing of the

product by the manufacturer, without any participation of a third party to the ongoing surveillance of

factory production or site installation;

⎯ system B: qualified contractor's declaration of conformity, based on the installer's documented installation

procedures and internal quality control and initial type testing of the components by a laboratory

accredited in accordance with ISO 17025, where both the manufacturer's quality control and the installer's

quality control has been certified initially by a third party; there is ongoing surveillance for the factory

production control but not for the site installation;

⎯ system C: installed product certification by a certification organization in accordance with ISO 17021 and

ISO/IEC Guide 65, based on the installer's documented installation procedures and internal quality

control and initial type testing of the components by a laboratory accredited in accordance with

ISO 17025, where both the manufacturer's quality control and the installer's quality control has been

certified initially by a third party; the certification organization certifies the installer in accordance with

ISO 17024 and ongoing surveillance site audits are conducted on a regular basis by the certification

organization accredited in accordance with ISO 17020.

NOTE Systems B and C have a progressive increase in third-party involvement in the conformity control system.

4.2 System A — Declaration of conformity by a qualified contractor — Initial type testing of

manufacturer's product, manufacturer's internal quality control and qualified contractor's

internal site quality control
This system is based on the following elements:
a) manufacturer's responsibilities:
⎯ factory production control;
⎯ having initial type testing of the components completed by the manufacturer;
b) qualified contractor's responsibilities:
⎯ self-declaration of conformity following requirements outlined in ISO 17050-1;
⎯ document site quality-control programme;
c) qualified installer's responsibilities:

By the qualified contractor's declaration of conformity, the contractor verifies that the installation is under a site

quality-control program and that the results of the site quality-control program show that the installed products

are in conformity with the product specification and any applicable installation standards.

4.3 System B — Declaration of conformity by an installer — Initial type testing of

manufacturer's product by a third party, third-party verification of factory production control,

verification of a qualified contractor's site quality-control program and site quality control by

a qualified contractor
This system is based on the following elements:
a) manufacturer's responsibilities:
⎯ factory production control;

⎯ having initial type testing of the components completed by a laboratory accredited in accordance with

ISO 17025;
b) qualified contractor's responsibilities:
⎯ document site quality-control program;
c) qualified installer's responsibilities:
⎯ documented installation procedures;
⎯ ongoing site inspection and testing by the installer;
⎯ daily work records by the installer;

d) certification organization, in accordance with ISO 17021 and ISO/IEC Guide 65:

⎯ testing laboratory accredited in accordance with ISO 17025;
⎯ initial inspection of factory production control;
⎯ ongoing surveillance audits of factory production control;

⎯ initial inspection of the qualified contractor's installation procedures, site quality-control program,

installer's site inspection, installer's site testing procedures and daily work record.

By the qualified contractor's declaration of conformity, the qualified contractor verifies that the installation is

under a site quality-control program that has been verified by a third party and that the results of the site

quality-control program show that the installed product is in conformity with the product specification and any

installation standards. The qualified contractor also declares that the factory production control has been

verified and is being monitored by a certification organization. Certification bodies shall be in accordance with

ISO 17021 and be accredited by an accreditation body that is member of the IAF/ILAC Multilateral Agreement.

4.4 System C — Declaration of conformity by a third party — Initial type testing of

manufacturer's product by a third party, third-party verification of factory production control,

verification of a qualified contractor's site quality-control program and site quality control by

a third party
This system is based on the following elements:
a) manufacturer's responsibilities:
⎯ factory production control;

⎯ initial type testing of the components completed by a laboratory accredited in accordance with

ISO 17025;
b) qualified contractor's responsibilities:
⎯ document site quality-control program;
c) qualified installer's responsibilities:
⎯ documented installation procedures;
⎯ ongoing site inspection and testing by the installer;
⎯ daily work records by the installer;
d) certification organization, in accordance ISO 17021 and ISO/IEC Guide 65:
⎯ testing laboratory accredited in accordance with ISO 17025;
⎯ initial inspection of factory production control;
⎯ ongoing surveillance audits of factory production control;

⎯ initial inspection of the qualified contractor's installation procedures, site quality-control program,

installer's site inspection, installer's site testing procedures and daily work record;

⎯ development of a certification scheme in accordance with ISO 17024;

⎯ routine certified installer audits to provide surveillance, assessment and approval of the ongoing

in-situ product installation (routine inspections) in accordance with ISO 17020.

By the certification organization's declaration of conformity, the certification organization verifies that the

installation is under a site quality-control program that has been verified and is monitored on an ongoing basis

by a third party and that the results of the site quality-control program show that the installed products are in

conformity with the product specification and any installation standards. Certification bodies shall be in

conformance with ISO 17021 and be accredited by an accreditation body that is member of the IAF/ILAC

Multilateral Agreement. The certification organization also declares that the factory production control has

been verified and is being monitored. The certification organization for the factory production control may be a

different organization from the certification organization for the site quality-assurance program; however, the

certification organization for the site quality-assurance program shall be consistent with that for the factory

production control program.

5 Factory production control

The purpose of the control is to ensure the products produced conform to the material specification. Factory

production control requirements shall be in accordance with ISO 12576-1. The manufacturer shall choose and

document which system in accordance with ISO 12576-1 is being followed. The manufacturer shall meet the

factory-production-control and certification-organization-monitoring outline in any one of the three systems.

For material that takes its final form on a construction site, this part of ISO 12576 specifies the requirements to

ensure that the products produced conform to the material specification.
6 Site installation control
6.1 General

The purpose of the site installation quality control is to ensure that the in-situ products conform to the product

specification and that they have been installed in accordance with the appropriate installation standard(s) and

in accordance with the product manufacturer's instructions. Site installation quality control, as defined in

Clause 6, is the most important element of each of the three systems defined in ISO 12576-1 for the

attestation of conformity.

Site installation quality control includes the operational techniques and measures necessary to maintain and

regulate the quality of the installed product. It consists of continuous process monitoring, inspections and tests

by the installer and the utilization of their results with regard to equipment settings, products used, processes

of installation, and the installed product itself, and by taking account of the corresponding requirements given

by the product specification.

All equipment and personnel required to carry out the necessary inspections and tests ind
