GS6-2 of 11 British Telecommunications plc 2001 Issue 15: (01/02)NOT SUBJECT TO ISSUE CONTROL WHEN PRINTED

1. Scope

This Standard details BT's generic requirements for the safety of goods. Compliance with this Standard does not, of itself, confer immunity from legal obligations.

2. Terms and Definitions The terms and definitions of IEC950 shall apply, and where used in this Standard are indicated by the use of SMALL CAPITALS. The term "goods" shall include items, equipments, machinery and products, and may represent a single item or multiple items, i.e. a system.

3. Invitation to Tender Response To each "Requirement" in Section 4 of this Generic Standard you are required to make a declaration of "Compliant", "Partially compliant" or "Non-compliant" as appropriate. This declaration shall be followed by a concise supporting statement describing the way in which you comply, or why you do not. Note: You should respond "Not Applicable" in those instances where the

Requirement does not apply to the goods being tendered for. If you have already responded to this issue of this Generic Standard, and intend to refer to all or part of your earlier submission, you must state the date the previous submission was made, the tender reference number, and the buyer to whom the submission was sent. You should note that BT reserves the right to validate the information given in your submission.

4. Generic Requirements for Safety

4.1 General Requirements



4.1.1 The supplier of the goods shall have documentary evidence to show that the goods comply with the requirements of this Standard.

4.1.2 The supplier shall ensure that the goods meet the requirements of this Standard following any installation, commissioning, maintenance or repair work carried out by the supplier.

4.2 Additional Requirements - Electrical 4.2.1 Goods for use within the European Community (EC) shall comply

with European Directive 73/23/EEC (otherwise known as the low voltage directive) as amended by Directive 93/68/EEC and shall bear the CE mark accordingly. The EC declaration of conformity and if requested such documentation (test results, reports, certificates etc.) making up the Technical Documentation shall be made available for inspection by BT.

Note: The preferred standard for demonstrating compliance with Directive 73/23/EEC is EN 60950. Where an alternative applicable standard is used (e.g. see 4.2.3 below) the order of priority shall be, (1) a harmonised European standard, (2) an International standard (e.g. IEC 65 or IEC 950), and (3) a National standard. Where an alternative standard to EN 60950 is used it shall offer at least an equivalent level of safety, and if the goods are intended for use outside the EC it shall be acceptable in the intended country of use.

4.2.2 Goods intended for use within the UK shall comply as follows:

a) Goods that will be part of a TELECOMMUNICATION

NETWORK, shall comply with the appropriate parts of clause 6 of EN 60950. In some circumstances the application of clause 6.4 may be inappropriate and advice should be sought from BT in case of doubt.

b) Goods that will be connected directly or indirectly to a

TELECOMMUNICATION NETWORK, shall comply with European Directive 1999/5/EC (otherwise known as the radio and telecommunications terminal equipment directive).

c) For goods weighing more than 18kg, a removable

ENCLOSURE guarding a HAZARDOUS VOLTAGE or a HAZARDOUS ENERGY LEVEL shall clearly display a safety



sign. The safety sign shall conform to BS 5378 and include the value of the principal HAZARDOUS VOLTAGE or HAZARDOUS ENERGY LEVEL.

d) Power supply cords for connection to plugs complying with BS1363 shall be BASEC approved and/or HAR marked. The conductor insulation shall be coloured as follows: - brown - phase, blue - neutral and, for Class I equipment, green/yellow - earth.

e) Three phase equipment shall be connected via plugs, socket-outlets and couplers for industrial purposes complying with EN 60309. Cords shall be BASEC approved and/or HAR marked with the phase conductor insulation in accordance with current regulations. The earth conductor shall be green/yellow.

4.2.3 Uninterruptible power systems for use within restricted access

locations shall comply with EN 50091. The preferred method for protection in the event of ac failure is automatic back feed protection, although BT will consider alternatives on a case by case basis.

4.3 Additional Requirements - Mechanical

4.3.1 Goods intended for use within the EC that are classified as machinery shall comply with European Directive 89/392/EEC as amended by Directive 93/68/EEC and the appropriate requirements of EN 292 or BS 5304.

4.3.2 For goods intended to be used in a rack or cabinet, the insertion

and withdrawal arrangements shall be such that the goods can be inserted and removed safely. A mechanical aid shall be available if the insertion or withdrawal force is greater than 90 newtons.

4.3.3 If the goods weigh greater than 10kg and are intended to be mounted in a rack or cabinet then the weight must be shown on the goods. The position of the marking must be such that it will be clearly visible before an attempt is made to withdraw the unit from the rack or cabinet.

4.4 Additional Requirements - Substances



4.4.1 The goods shall not contain any substance in a form that is

hazardous to health unless no suitable alternative exists.

4.4.2 Goods intended for use within the UK shall comply with the following: a) Where goods contain or produce a substance hazardous to

health as defined by the Control of Substances Hazardous to Health Regulations 1988 (COSHH), the supplier shall provide suitable and sufficient Safety Information in accordance with Section 6 of the Health and Safety at Work Act 1974

b) For goods containing or using chemicals, the supplier shall

provide BT with Hazard data sheets in accordance with the requirements of the Chemicals (Hazard Information and Packaging) Regulations 1993 (CHIP) and the packaging shall be labelled accordingly.

c) The supplier shall provide BT with details on the safe

disposal of waste arising from goods or chemicals supplied. d) The supplier of goods containing radioactive substances shall

provide the relevant details to the buyer for forwarding to the BT Radiation Protection Adviser.

4.5 Additional Requirements - Radiation 4.5.1 Where goods emit radio frequencies in the range 1Hz - 300GHz,

they shall comply with the International Commission for Non-Ionising Radiation Protection (ICNIRP) recommended derived general public exposure limits to RF electromagnetic fields.

In particular the goods shall where appropriate comply with the standards from time to time specified in the General public exposure Basic restrictions for time varying electric and magnetic fields up to 10GHz section of the guidelines issued by ICNIRP and in the Restrictions on exposure to static and time-varying electromagnetic fields issued by the UK National Radiological Protection Board.

The supplier shall demonstrate compliance with these standards by reference to appropriate test methods and test results which shall be made available to BT on request.



4.5.2 Where goods use radio frequency power in excess of 25 watts, this level of power shall not be accessible in OPERATOR or SERVICE ACCESS AREAS.

4.5.3 Where goods emit X-rays, the emissions shall not exceed 0.5mr/h

(milliroentgens per hour) at a distance of 50mm from any accessible surface. All goods emitting X-rays will need to be assessed under the Ionising Radiations Regulations 1985. Relevant details shall be provided to the buyer for forwarding to the BT Radiation Protection Adviser.

4.5.4 Where goods emit ultra violet radiation, leakage emissions in the

wavelength range 200 - 400 nanometres shall be limited so that personal exposure cannot exceed the relevant ACGIH limits.

4.5.5 Where goods use lasers and/or LEDs, the goods shall be classified

according to EN 60825-1 (IEC 60825-1 is equivalent).

For optical fibre communications systems, the goods shall also be classified according to EN 60825-2 (IEC 60825-2 is equivalent). The BT procurement specification for any optical fibre communications system shall state which classifications are permissible (Classes 1, 2, 1M and 2M only). This power restriction does not apply to Submarine Systems, which will never be worked on live. Optical fibre communications systems of all classes shall be labelled according to EN 60825-1.

The EN 60825-2 standard for optical fibre communications systems requires classification to be based on radiation that could become accessible under "reasonably foreseeable circumstances". The tenderer shall demonstrate that there is a high degree of assurance that this classification will not be exceeded; the probability of exceeding Class 1M or 2M limits shall not exceed 500 FITs (excluding Submarine Systems). The method of analysis, assumptions made and results obtained shall be stated by the tenderer and reported to BT.

BT will only deploy systems of Hazard Level 1M/2M or lower in its inland networks. However, higher powered (higher class) systems may be used providing they comply with Hazard Level 1M/2M, by using Automatic Power Reduction (APR), Automatic Power Shut-Down (APSD) or similar. This will reduce power levels to class 1M/2M or lower under a fault condition (such as cable break or connector disconnection). Note that Submarine



systems using armoured and/or segregated cables are excluded from these requirements. NEW equipment may be classified to the old standard and use class/hazard level 3A etc, until the withdrawal of this standard on 31/Jan/2004. EXISTING equipment may remain classified and/or labelled class/hazard level 1 or 3A to the previous standard indefinitely (i.e. there is NO need to relabel existing correctly labelled equipment or products).

4.6 Additional Requirements - Temperature

The temperature of air issued from the goods shall not exceed +75C.

4.7 Additional Requirements - Ozone Emission

Where goods produce ozone, they shall comply with the final paragraph and Note 5 to 1.7.2 of EN 60950 regardless of which specification is adopted for compliance with 4.2.1 of this Generic Standard, and the supplier shall provide installation and maintenance requirements that minimise the room concentration of ozone to the lowest level practicable.

4.8 Additional Requirements - Software

The safety of the goods shall not be degraded by the operation (correct or otherwise) of any software, firmware or any other stored information that is part of the goods.

4.9 Additional Requirements - Noise Emissions

Goods intended for use within the UK that are for use in "office type" environments shall not emit noise levels greater than 77dB(A) at the operators ear and not greater than 73dB(A) at 1.5 metres from the goods in any plane.

Note 1: The noise levels are measured with the goods in the normal

operating mode with any silencing systems operated. Note 2: A harmonised standard specifying absolute limits for noise

levels is currently in draft form. When that standard is published it will replace the above requirements.



4.10 Additional Requirements - Safety Signs

Safety Signs and Fire Signs that are part of the goods shall comply with the relevant National Standards. (For the UK the standards are BS5378 for safety signs and BS5499 for fire signs).

4.11 Additional Requirements - Alarms, Indicators & Messages

4.11.1 Panel type alarms and indicators that are part of the goods shall be

clear and concise. The following colours shall be used as detailed in EN 60073 (IEC 73 is equivalent) (see also 1.7.8.2 of EN60950):-

Red: Indication of a fault or a warning.

Green: Safe and satisfactory running condition.

White: Status, mode or other neutral information, implying neither success nor failure.

Yellow: An information or caution condition. 4.11.2 Visual Display Unit alarms, indicators and messages shall be

clear and concise.

4.11.3 Alarms or indicators which could affect safety shall be fail-safe or be protected by a suitable system of redundancy.

4.11.4 Buttons (controls) that are activated in emergency situations shall

be positioned such that they are not subject to accidental operation. The buttons shall be coloured red and suitably labelled as to their function.

4.12 Additional Requirements - Manuals, Handbooks, Instructions

4.12.1 OPERATOR manuals, handbooks or instructions associated with the

goods shall include details on how to safely operate the goods and safely carry out any OPERATOR maintenance.

4.12.2 Servicing manuals, handbooks or instructions associated with the

goods shall include details on how to safely service the goods.



4.13 Additional Requirements - Training

4.13.1 OPERATOR training associated with the goods shall include instructions on how to safely operate the goods and safely carry out any OPERATOR maintenance.

4.13.2 Training and courses for SERVICE PERSONNEL shall include instructions on how to safely service the goods.

4.14 Additional Requirements - Personal Safety Goods

Personal safety goods shall comply with European Directive 89/686/EEC as amended by Directives 93/95/EEC and 93/68/EEC. The suppliers quality system shall ensure that the safety features of the goods are 100% inspected, however where tests are destructive, sampling techniques shall be used. The sampling frequency for destructive tests shall be agreed with BT.
