BS EN 140100-2008 PDF

Full title and description

STB BS EN 140100-2008 — Sectional specification: Fixed low power film resistors. This publication is the EN 140100:2008 European sectional specification that sets preferred values, ratings, inspection and test requirements applicable to leaded fixed low-power film resistors (intended principally for PCB mounting). It is presented here under national adoption prefixes (STB and BS) as issued in 2008.

Abstract

EN 140100:2008 is a sectional specification which selects from the generic fixed resistor specification the appropriate characteristics, ratings and test/inspection methods for fixed low power film (film/foil) resistors. It provides the basis for detail (blank) specifications used for product qualification and quality conformance inspection and references the generic test methods of EN/IEC 60115 series. The document was published in 2008 and has subsequently been superseded in many jurisdictions by later IEC/EN documents addressing fixed resistors.

Scope

This sectional specification applies to leaded fixed low power film resistors. It prescribes preferred values for characteristics and ratings, the inspection requirements and the detailed selection of test methods from the generic specification (EN/IEC 60115-1). The standard is intended to be used as the basis for creating blank detail specifications for specific resistor types and for establishing requirements used in qualification and quality conformance systems (for example IECQ/CECC schemes). National adoptions (BS, STB, BDS, etc.) may include local status information and withdrawal dates.

Key topics and requirements

• Designation and scope for fixed low power film resistors (leaded, PCB-mounted types).
• Preferred values for resistance, power rating and tolerances appropriate to low-power film resistor families.
• Selection of test methods and conditions from the generic resistors specification (EN/IEC 60115-1) for use in detail specifications.
• Inspection and quality conformance requirements suitable for product qualification and routine inspection.
• Requirements for marking, documentation and delivery conditions used in supply and procurement.
• Reference to related detail specifications (blank detail specifications) that can be used for granting approvals and conformity assessment.

Typical use and users

Manufacturers of film resistors, component procurement and purchasing engineers, test laboratories, certification and quality-assurance bodies (IECQ/CECC), design engineers specifying passive components for electronic equipment, and national standards committees. The specification is used to derive detailed product specifications and to set inspection/test regimes for contract acceptance and quality control.

Related standards

EN/IEC 60115 series (generic fixed resistor specifications and test methods), EN 140100:1996 and EN 140100:1996/A1:2001 (earlier editions), and later consolidating standards such as EN/IEC 60115-2 (Fixed resistors for use in electronic equipment — Part 2: sectional specifications for leaded fixed low power film resistors) which supersede or absorb many sectional requirements. National adoptions and replacement notices (withdrawals) are published by individual national bodies.

FAQ

Q: What is this standard?

A: EN 140100:2008 is a European sectional specification titled "Sectional specification: Fixed low power film resistors" (published/adopted in 2008). The title STB BS EN 140100-2008 indicates national adoption labels (STB and BS) applied to the EN text.

Q: What does it cover?

A: It covers preferred characteristics, ratings, inspection requirements and the selection of appropriate test methods (from the generic EN/IEC 60115 series) for leaded fixed low power film resistors. It is intended to be used as the basis for blank detail specifications and for qualification and quality-conformance procedures.

Q: Who typically uses it?

A: Component manufacturers, procurement/specification engineers, test houses, conformity-assessment bodies (e.g., IECQ/CECC participants), and standards committees who need a harmonized sectional specification for fixed low power film resistors.

Q: Is it current or superseded?

A: The 2008 EN document has been withdrawn or superseded in many jurisdictions. The EN/IEC 60115 series (notably the Part 2 sectional specifications published after 2015) has been used to consolidate and replace earlier sectional specifications. National withdrawal dates vary (for example some national adoptions show withdrawal around 2010–2018), and EN 60115-2:2015 is the later consolidating reference for leaded low-power film resistors.

Q: Is it part of a series?

A: Yes — EN 140100 is a sectional (particular) specification that works together with the generic EN/IEC 60115 series. It superseded earlier EN 140100 editions (1996 and 1996/A1:2001) and is related to other EN/IEC parts dealing with fixed resistors and their sectional/detail specifications.

Q: What are the key keywords?

A: Fixed low power film resistors; sectional specification; EN 140100:2008; leaded resistors; film resistors; inspection; test methods; EN/IEC 60115; blank detail specification; quality conformance.
