IEC 1010 is an international standard in several parts. It is also issued as a Eurpoean Standard (EN 61 010) and is also a VDE specification (VDE 0411). The purpose of this standard is to protect the user, by means of approriate designs, against the following hazards (extract):
The standard does not deal with the reliable function, performance or other properties of the devices, or their servicing. The standard applies to the following devices:
WHAT DOES THIS STANDARD MEAN FOR HIRSCHMANN PRODUCTS?
As a significant supplier of laboratory equipment, Hirschmann offers a complete range of contact-protected measuring leads and measuring equipment. Customer-specific bespoke solutions are in use throughout the world. According to this standard, hazardous currents do not occur below the safety low voltage of 60 V DC and 30 V AC or 42.2 V AC peak value. Contact protection in accordance with IEC 1010 is not necessary. The entire Hirschmann laboratory equipment range is suitable for this. Voltages above the safety low voltage can cause hazardous electric shocks. Hirschmann offers a safety laboratory equipment range designed in accordance with IEC 1010 for this area. If used properly it guarantees safety up to 1000 V. The safety laboratory equipment range has been type-tested by the accredited test laboratory at TUV Sudwest. The products marked in the catalogue and identified on the packaging have been tested to IEC 1010. This means that Hirschmann products comply with international safety standards and are recognized throughout the world as reliable and high-quality products.
A distinction is made between basic insulation and double or enhanced insulation. The standard specifies double insulation for hand-held measuring accessories. This comprises the basic insulation which guarantees minimum protection against hazardous electric shocks, and an additional insulation which ensures protection against hazardous electric shocks in the event of failure of the basic insulation. Hirschmann uses at least double insulation to protect the user of all products in the safety laboratory equipment range.
With few exceptions, Hirschmann has designed the entire safety laboratory equipment range for 1000 V, surge overvoltage category 3 and pollution degree 2. This is certain to cover the greatest range of measuring tasks in the higher voltage range. It is possible to achieve a different measuring voltage by definition of different ambient conditions. Hirschmann will be happy to advise you on assessing safe use at higher voltages.
Safety laboratory equipment may only be touched in the hand held area whenever there is a hazardous voltage. The grip area is the area in which the user can touch an item of measuring equipment in use without being exposed to hazardous electric shocks. The area is marked on the equipment and identified in the catalogue. Safety measuring leads complying with IEC 1010 are crimped and are provided with strain relief on the lead and the lead insulation. The values demanded by the standard are exceeded by a long way. The leads are thus particularly robust and durable. The measuring leads are injection-moulded and are fitted with kink-protection providing effective protection to the lead outlet. The enhanced strain relief is not intended as an invitation to use the lead as a lever to unplug the connector. The hand held area provided on the connector must always be used for this purpose.
The basic insulation is the minimum insulation the failure of which can cause a risk of an electric shock.
Is the protection of measuring equipment against unintentional contact. Contact protection is dependent on the voltage to be measured, the transient voltages to be anticipated (surge overvoltage category) and the ambient conditions (degree of pollution), and of the insulation. In order to achieve optimum contact protection, all products in the safety laboratory equipment range are provided with double or enhanced insulation (protective insulation). Hirschmann has designed the entire safety laboratory equipment range, with a few exceptions, for surge overvoltage category 3 and degree of pollution 2. This is certain to cover the greatest range of measuring tasks up to 1000 V. It is possible to achieve a different measuring voltage by definition of different ambient conditions. Hirschmann will be happy to advise you on assessing safe use at higher voltages.
The operating voltage is the voltage specified by a manufacturer for his equipment and to which the operating and performance characteristics are related.
The rated current is the current flowing through all contact elements simultaneously which a connector system can carry in normal operating and ambient conditions (room temperature of 25°C) without its limit temperature being exceeded.
CADMIUM, FORMALDEHYDE, ASBESTOS
Hirschmann connectors use only pastics that are free from cadmium, formaldehyde and asbestos.
At higher ambient temperatures, the rated current should be reduced in accordance with the derating curve (see DIN 41 640 Part 3). The current-carrying capacity of connectors is limited by the thermal capacity of the contact materials and insulation. The derating curve thus applies to currents that may flow constantly through any contact element of a connector without the upper limit temperature being exceeded.
Is an insulation comprising basic insulation and additional insulation (see also Contact protection).
The volume resistance is the resistance measured across the terminals of connected contacts. It comprises the bulk resistances and the contact resistances. Tested in accordance with DIN 41640.
HAND HELD AREA
The hand held area is the area in which a user can touch measuring equipment without being exposed to the risk of electric shock. The area is marked on the equipment and identified in the catalogue (safety laboratory equipment range).
The international standard Safety requirements for electrical equipment for measurement, control and laboratory use, which defines the protection of the user against electric shock, electrical burns... The standard is identical to European Standard EN 61 010 and the German specfication VDE 0411. All Hirschmann products in the safety laboratory equipment range are designed to comply with this standard and are tested by an accredited testing laboratory (see product descriptions).
The cable outlet is provided with a flexible kink protector which effectively prevents the lead from breaking in the critical area. These special features guarantee safety for the user, reliable measurement results and the prolonged service life of the measuring leads themselves.
The creepage distance is the shortest distance between two conducting parts along the surface of insulation. All raised areas and depressions in the insulation are taken into consideration.
The air gap is the shortest distance through the air in a straight line between two conducting parts.
MEASUREMENTS UNDER EXTREME AMBIENT CONDITIONS
Connectors are subjected to various tests in the Hirschmann tests laboratories. The products are tested with high voltages, and exposed to high air humidity and aggressive atmospheres. Tropical and Arctic ambient conditions are simulated in testing cabinets, industrial atmospheres can be simulated in the hazardous gas test cabinet. Contacts can be tested by non-destructive means using x-ray equipment. The electro-dynamic vibration system can expose connectors to accelerations up to 85 g with simultaneous exposure to various temperatures.
Hirschmann products are tested with high voltages in the design and production phases to ensure insulation capability and breakthrough resistance under the specified conditions. The voltage level depends on the application and is specified in various standards such as IEC 1010. The test voltage is a multiple of the operating voltage and is met or even exceeded by all products.
SAFETY EXTRA-LOW VOLTAGE
Safety extra-low voltage is 25 V AC and 60 V DC according to VDE 0100 Part 410. Measuring equipment without contact protection may be used below this voltage level. The relevant national regulations must be complied with.
A mating cycle comprises one insertion action and one withdrawal action. The number of mating cycles depends on the connector pin and the associated socket. Thanks to the use of high quality contact materials, Hirschmann products withstand a greater number of mating cycles and thus have a longer service life.
As a rule, there are manufacturers' data available for the resistance to radiation. An assessment of the resistance to energy radiation states the dose sufficient to damage the plastic sufficiently for a significant mechanical property to be reduced to one half of its value.
Permissible range within which the connector may be used without the material being damaged. The derating curve shall be taken into consideration in determining the current in the upper temperature range.
A transient is a surge voltage created as a result of a switching procedure or a lightning discharge. The transient voltages are specified in the standards, IEC 1010 for instance, and depend on the ambient conditions and the location in the supply network at which the measurement is taken.
TUV TEST MARK
Various products are type-tested by TUV Sudwest, which is an accredited testing laboratory. Products so identified have been tested in accordance with DIN VDE 0411 Part 1, IEC 1010-1 and E DIN VDE 0411 Part 113, IEC 1010-2-031. Hirschmann products thus comply with international safety standards and are recognized throughout the world as being reliable, high quality products. Applications have been submitted to TUV Sudwest for type testing in respect of various products. The are designed in accordance with IEC 1010.
SURGE OVERVOLTAGE CATEGORY
The user may be put at risk in electrical networks as a result of transient surge voltages. The surge voltage categories define the hazards that may arise in certain applications. Surge overvoltage category 1: Signal voltages within devices, special devices, electronics, battery devices, etc. in which only low surge voltages may occur. Surge overvoltage category 2: Devices, portable devices in which transiet surge voltages may be generated by switching processes, e.g. mains-supplied consumer electronic equipment, domestic appliances,... Surge overvoltage category 3: Voltages in the area of distribution boards and fixed installations, (e.g. domestic installations) with surge voltages. Surge overvoltage category 4: Voltages on overhead cables, cable networks, etc.
Hirschmann has designed the entire safety laboratory equipment range, with a few exceptions, for surge overvoltage category 3 and degree of pollution 2. This is certain to cover the greatest range of measuring tasks up to 1000 V. It is possible to achieve a different measuring overvoltage by definition of different ambient conditions. Hirschmann will be happy to advise you on assessing safe use at higher overvoltages.
Standard IEC 1010 defines two degrees of pollution Pollution degree 1: permits no pollution, or only minor, non-conducting pollution. Pollution degree 2: is a minor, normal pollution, which may become conducting as a result of occasional condensation. This pollution may be created by perspiration and is thus to be assumed on hand-held measuring accessories.
All Hirschmann safety laboratory equipment products are designed for pollution degree 2.
Insulation providing protection against hazardous electric shock, being not less than that provided by double insulation (see also contact protection).
STRAIN, STRAIN RELIEF
Safety measuring leads complying with IEC 1010 are crimped and are provided with strain relief on the conductor and the insulation. The values demanded by the standard are far exceeded. The leads are thus particularly robust and highly durable. The measuring leads are injection-moulded and are provided with a kink protection which is effective in protecting the cable outlet.
CABLE DAMAGE TELL-TALE SYSTEM
All the measuring leads in the 4 mm system are provided with a colour tell-tale system. The cable insulation consists of two separate insulating layers, the first of which is in direct contact with the copper wires and is white in every case. A second insulating layer is applied at a subsequent production stage, whereby each cable acquires its distinctive colour, e.g. red. If the outer sheath becomes damaged through the use of the lead, the white insulating layer is exposed. For reasons of safety, the lead should be immediately replaced with a new Hirschmann measuring lead.
Hirschmann measuring leads are subjected to a variety of stresses and strains in everyday use. The quality of a Hirschmann lead is revealed not only by it's ability to withstand high voltages and currents, and extreme temperatures, but also by its exceptional durability. A particularly effective, durable bonding process is used to secure the lead to the plug. In addition, the connection between the plug and the lead insulation is crimped. This technique achieves the maximum degree of strain relief, well beyond the standards specified by official safety regulations.
