RISK

ASSESSMENT

Hazard analysis and risk assessment (HARA), required by the ISO EN 12100

standard, is used to identify malfunctions that involve hazardous behaviours,

assess the level of risk for each hazard and formulate machinery safety

countermeasures

XEFRA supports the Manufacturers and Integrators in the following safety

concept steps:

- Assembly definition Simplification process of the HARA through the

subdivision of the assembly into functional machinery

- Incidental Scenario catalogues We have developed a catalogue of

dangerous scenarios to simplify the approach to the Hazard identification

and thus reduce the manufacturer's effort

- Safety provisions: Definition of safety provisions outside the function for

further simplification of the HARA

- Risk analysis PL and SIL apportionment and duration or frequency

definition of the level of exposure to the operator's danger, as indicated in

the standard, can be based on duration or frequency

- Job Safety Concept development of a safety layout with guards

positioning and procedure which helps integrate accepted safety and

health principles and practices into a particular task or job operation.

- Control System Concept and Safety Logic Table: on the basis of the

defined safety functions, we help the manufacturer or the integrator in the

definition of the control system architectures. We participate in the

definition of the logical safety requirements of the assembly.

FUNCTIONAL

SAFETY

FOR

MACHINERY

XEFRA provides developers and testers of safety-related machine controls with

comprehensive support in the evaluation of safety in the context of ISO 13849-1.

We support you modelling the structure of the safety-related control components

based upon the designated architectures, thereby permitting calculation of the

reliability values with various levels of detail, including that of the attained

Performance Level (PL).

Relevant parameters such as the risk parameters for determining the required

performance level (PLr), the category of the SRP/CS, measures against common-

cause failures (CCF) on multi-channel systems, the average component quality

(MTTFd) and the average test quality (DCavg) of components and blocks, are

defined in our functional safety reports.

XEFRA delivery also the following services:

- development of life cycle with validation measures that indicate how and when

the SRP/CS should be validated, for example, following a change.

CYBERSECURITY

SERVICES

IEC 62443 series - Industrial Automation Control Systems (IACS)

IEC 62443 describes cyber security requirements for all industries and is composed by four parts.

IEC 62443-3-2 sets the requirements for risk assessment leading to the identification of zones and conduits for the

IACS. Based on the detailed risk assessment for each zone and conduit, the sufficient security level target (SL-T) for

each could be determined.

The SL-T guides which requirements and enhancements in IEC 62443-3-3 that should be evaluated to ensure

sufficient countermeasures.

The steps of XEFRA assessment are:

- analysis of the security technologies implemented;

- verification of the requirements of the IACS security management system;

- determination of the SL target for components and systems;

- ability to design with a view to security;

- risk analysis;

- definition and implementation of the necessary counter measures;

- analysis of possible threats;

- Quantitative assessment, with estimation of the probability of penetration into local networks;

- Penetration-test for the experimental detection of the vulnerability of the system.

MACHINERY

FOR FOOD

INDUSTRY

Materials and components intended to come into contact with food

MOCA – Materials and Articles Intended to Come into Contact with Food, refers to all items:

- that are intended to come into contact with food,

- that are already in contact with food and are intended for this purpose,

- that are expected to come into contact with food or that can transfer their components to food under

normal conditions of use.

Voluntary product verification or certification stems from a company need to ensure product conformity and

performance, in compliance with recognised regulations or proprietary standards, thereby enhancing the

value of and distinguishing their production on the market and gaining more trust from potential clients.

Requirements that can be certified must be measurable through objective parameters, certifiable by tests,

and verified by assessing and monitoring the manufacturing and verification plan of the production process,

with the purpose of ensuring conformity and initially verified quality over time.

Compliance audits conducted by a third-party body allow companies to demonstrate to the market the

correct compliance with legislative requirements, the adoption of good manufacturing practices, compliance

with the safety requirements of their products to protect human health.

The XEFRA MOCA certification is dedicated to all manufacturers of materials and objects that come into

contact with food.
