An Update regarding COVID-19

Dear business partners,

the situation around the corona virus (SARS-CoV-2) is developing very dynamically. With the support of our parent company HAWE SE, Schienle Magnettechnik is permanently monitoring the development. An internal crisis team has been in operation for weeks now and decides on measures on a daily basis that provide the best possible protection for our Group employees and do not unnecessarily endanger our business partners. At the same time all measures are aimed at reliably maintaining business operations for our customers.

We have thus been very successful in maintaining our delivery performance at the usual good level across all product groups. Thanks to our very high vertical range of manufacture and the predominantly local supplier network, the supply of parts is still ensured. Should delays nevertheless occur, you will be informed immediately and individually via the usual channels.

Trade fairs and major events are cancelled. Personal appointments and meetings are limited to a few unavoidable appointments. This serves to protect all parties involved. As an alternative we increasingly offer online meetings. Our employees in sales, purchasing and customer service are very well prepared and have various tools at their disposal for this purpose. Through a planned combination of home office and office presence, the usual contact persons are still available to you even under these special circumstances and can therefore be reached without restriction.

Ask specifically for online meetings or online presentations by our employees! Let us master this special situation together and perhaps even discover one or the other new communication channel with its advantages for the future.


See you at IFK 2020 in Dresden

This is what we want to discuss with you:

  • Mechanical Standards for Equipment in Explosive Atmospheres
    • What has changed in practice since the discontinuation of EN 13463, and what is the status of mechanical explosion protection in IECEx.
  • Digital shadow in explosion protection – Explosion protection products with footprint
  • Our experience with China Compulsory Certification CCC Ex (CNCA-C23-012019)

From October 1, 2020 CCC-certification will become mandatory for all Ex-products in China.

Implementing regulation CNCA-C23-01:2019 overturns the current exemption clause which exempts products with Ex certification from the need for a CCC (China Compulsory Certification).

 

Products for use in hazardous locations are currently classified in 17 categories, and with effect from 1 October 2020, the following Ex products are subject to compulsory CCC certification:

  • Ex motors
  • Ex pumps
  • Ex power distribution devices
  • Ex switches, control and protective device
  • Ex starters
  • Ex transformers
  • Ex actuators, valves
  • Ex plugs and sockets
  • Ex monitoring devices
  • Ex communication, signal devices
  • Ex air conditioning, ventilation system
  • Ex electrical heating devices
  • Ex accessories, Ex components
  • Ex instruments
  • Ex sensors
  • Safety barriers
  • Ex instrument cabinets

 

What does compulsory CCC certification for Ex Equipment in China mean, exactly?

From 1 October 2020, valve solenoids for use in the mining industry in China require a CCC certificate in addition to existing MA approval.

In industries other than mining, valve solenoids for use in hazardous (classified) locations require CCC Ex approval. This can be obtained in a three-stage process based on an existing ATEX or IECEx certificate.

 

The individual stages of the process:

Stage 1: Type test (Ex product assessment, tests and certification)
Stage 2: Initial inspection at the product manufacturer’s premises
Stage 3: Repeat audit (surveillance audits and reassessment audits)

 

The most important change:

The IECEx QAR (Quality Assessment Report) is not accepted as proof for the CCC quality monitoring procedure, and the CCC surveillance and reassessment audit procedure does not correspond with that of the IECEx system. This means additional and increased effort and expense for the initial inspection and subsequent inspection.

 

We would be pleased to answer your detailed questions directly.

New standard for mechanical explosion protection: EN ISO 80079-36 and -37

With effect from 2016, the previously well-known standards EN 13463-1:2009 and EN 13462-5:2011 ‘c’ were replaced by the latest generation of standards EN 80079-36:2016-12 ‘h’ and EN 80079-37:2016-12 ‘h’.

A presumption of conformity applies to the earlier standard. This means that, during a transitional period of three years (until May 2019) this does not lose its validity.

Caution:: Consider competitors’ behaviour and customer behaviour. It can be assumed that equipment complying with the new standard is already in circulation, and that in the medium term, customers or IECEx national bodies will demand the new designation.

ATEX mechanical EX-protection – What’s changed:

  1. Designation: Irrespective of the ignition protection type, the letter ‘h’ is always assigned.
  2. The ignition protection types are described in EN 80079-37. Proceed as with EN13463-5:2003. In terms of ignition protection type, constructional safety is virtually unchanged. The table in EN13463 Part 1 is still recommended for assessing the danger of ignition.
  3. There is no longer a TX designation
  4. Analogous to electrical ignition protection, the EPL has been introduced. This means that not only the zone now determines equipment selection, but that the effect of the explosion is now also taken into account.
  5. If the actual maximum surface temperature no longer depends on the equipment itself, but mainly depends on the operating conditions, the manufacturer can no longer assign a designation with a temperature class or temperature. Instead, the designation must include a T-range or ambient temperature range (eg T6…T4 or 85°C…150°C).
    Furthermore, there are some particular characteristics that apply to equipment in Group II Gb and Gc: for example, when carrying out the type test, safety margins depend on the temperature classes.
  6. The combined GD designation can no longer be used for gas and dust. As is the case with electrical Ex protection, designation is divided into Gas G/Dust D.

Note:

Whether a mechanical device is subject to the directive is described in the guide notes to Directive 2014/34/EU Section 42.

IECEx mechanical EX-protection – What’s changed:

Everything, because this did not exist until now!

  1. IEC-Ex has incorporated non-electrical standards IEC 80079-36 and -37.
  2. At the time of writing (May 2017), there are hardly any certification bodies inspecting this standard in the IEC process.
  3. Applicable to purely mechanical equipment as well as equipment with clearly mechanical parts (solenoid valve).
  4. Conformity assessment procedure will be applied in accordance with ATEX/IECEx.
  5. IECEx sees the expansion as a ‘proposal’!
  6. In the valve sector, the first approvals are already taking place. What effects this will have on the acceptance of mechanical equipment that has not been inspected to IEC standards is open to speculation.
  7. The process resembles that relating to electrical Ex protection. COC and QAR issue the certificate. In the IECEx scheme, inspection by a third party is obligatory. This applies to both the product and the process.


U.S. Coast Guard updates electrical regulations for offshore hazardous locations

The U.S. Coast Guard (USCG) is responsible for maritime safety and security in the U.S. Offshore Continental Shelf. USCG recently published amendments to the Title 46 CFR rules governing electrical equipment used offshore in hazardous locations.

These changes have the potential to affect builders and suppliers of equipment used on all gas and oil rigs, mobile offshore drilling units and offshore supply vessels.

Changes to take effect in 2018

In a ruling published in the Federal Register (Vol. 80, No 61) on 31 March 2015, the U.S. Coast Guard (USCG) significantly updated Title 46 of the Code of Federal Regulations (CFR), Parts 100 and 111. Scheduled to take effect on 2 April 2018, all equipment used on rigs, mobile offshore drilling units (MODU) and offshore supply vessels (OSV) in the U.S. Offshore Continental Shelf (OCS) must meet stringent new rules governing the use of electrical equipment in hazardous locations.

Currently, the USCG permits electrical equipment to be used on MODU, OSV, and similar vessels or installations operating in the OCS only after it has been certified by an independent laboratory to 46 CFR 110.15-1. This has now been superseded by a requirement that ñ from 2018 ñ all such equipment must be certified or listed in accordance with either National Regulations or the IECEx Scheme (the International Electrotechnical Commission System for Certification to Standards relating to Equipment for use in Explosive Atmospheres).

For various reasons, the USCG does not permit the use of equipment certified solely under ATEX Directive 2014/34/EU. However, it does recognize that most ATEX-certified equipment may also be IECEx-certified, and/or that the certification body may also be a USCG independent laboratory, as defined in 46 CFR 110.15-1.

New constructions must have a HazLoc plan

Builders of rigs and similar installations are additionally affected by changes found in 46 CFR 110.25-1. This regulation now requires that any new construction must have a detailed plan for all hazardous area classifications and the equipment installed therein, even cables. ß110.25-1 specifies that all vessels with hazardous locations must have such plans, showing the extent and classification of all hazardous locations, including equipment specifications such as name and model number, installation details, and a certificate of testing by an independent laboratory or an IECEx Certificate of Conformity. Parameters of intrinsically safe systems must also be adhered to.

Incorporating industry needs

The USCG continually reviews its regulations and codes to maintain a high level of effectiveness and safety in the face of evolving technology and applications. In this case, the USCG initially solicited questions and other feedback from affected parties with a notification in the 24 June 2013 issue of the Federal Register.

Nearly two years later, the resulting ruling incorporates many of the comments and requests made through this process, and the 2018 date at which the new regulations go into effect can be seen as part of that, designed to not cause undue stress and hardship to the industry. Equipment manufacturers and suppliers therefore have approximately three years to comply with these new regulations and apply them to their business.

In addition to the amendments to 46 CFR, the documentation in the Federal Register includes a discussion of the comments received by USCG during the decision-making process, as well as details on the rationale ultimately applied.

For more information

Independent safety science companies like UL (Underwriters Laboratories) can offer guidance and assistance to manufacturers, operators, suppliers and builders in the gas and oil equipment field, to ensure that they understand ñ and are ready to meet ñ these and other new regulatory demands. UL has been providing hazardous location assistance to companies since 1915, and is accredited as an IECEx System Ex Certification Body (ExCB) and Ex Testing Laboratory (ExTL) for IEC hazardous locations standards.

Schienle Magnettechnik with new look at the Hannover Messe 2013

Schienle Magnettechnik with new look at the Hannover Messe 2013

For almost 15 years now, Schienle has been providing explosion proof solenoids. Now the company from Salem is presenting its new brand logo “World Wide ex-perience”.

At the same time, the new explosion proof brand logo “World Wide ex-perience” was the motto of Schienle’s appearance at the Hannover Messe 2013 this year, where the company exhibited its extensive explosion proof portfolio.

Exotic exhibits: Solenoid valve certificates from around the world
As visitors were able to experience at the well attended stand at the trade fair, Schienle not only has ATEX- and IECEx certificates, but also regional and application-specific certificates. A world map showed regionally required licenses, for example for mining or offshore applications. In our part of the world, these certificates are considered to be a rare breed. But in places where raw materials are mined on a large scale, they are an indispensable requirement for licensing solenoid valves.

Schienle receives US approval for Class I Division 1 Group C/D requirements

The Deep Water Horizon disaster off the Florida coast is not just a matter for the legal system, but has had direct effects on the safety requirements of technical equipment on offshore drilling platforms. For areas in which flammable gases, vapors and liquids such as for example

acetyls can regularly occur under normal operating conditions,  equipment use has been restricted to such devices as are certified according to IECEx or ATEX.

Under certain conditions, testing equipment to see if it meets US standards has become a legal condition within a very short period of just a few months. We have been able to give renewed proof of our high performance and flexibility in obtaining local approvals world-wide, by adjusting the design and construction of the valve control solenoids to meet local requirements and in obtaining in record time both the required US auditing of our EX production range, as well as the required certificates for the most highly endangered group, the Class I Division 1.
