8. Product safety and product related environmental protection
As a fundamental principle, all manufacturers have an obligation to supply safe products.
The products supplied must not represent any hazard to life or limb, health, property or the environment.
8.1. Conformity of ASM AS products
The primary markets for sales of ASM AS products are in Europe, North America and Asia.
Suppliers and manufacturers of products are obliged to observe the norms, standards and statutory requirements that
apply to their products in the relevant countries.
In addition, ASM AS must also observe the norms, standards and statutory requirements that apply to its products in these
countries.
For this reason, suppliers and manufacturers of products must also observe the directives and standards listed below for
the products supplied to ASM AS.
Directives and standards for Europe:
DIRECTIVE 2011 / 65 / EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL on the restriction of the use of
certain hazardous substances in electrical and electronic equipment (RoHS)
Directives and standards for P.R. China:
GB/T 26572-2011 Requirements for Concentration Limits for Certain Restricted Substances in Electrical and Electronic
Products.
SJ/T 11364-2014 Marking for the Restricted Use of Hazardous Substances in Electronic and Electrical Products.
Directives and standards for North America:
UL 508 Industrial Control Equipment
UL 94 Flammability of Plastic Materials for parts in Devices and Appliances
Product-related requirements in respect of norms and standards that go beyond this are defined in the product
specifications.
Supplementing information and requirements to the product related environmental protection see also chapter 9.7.
8.2. Archiving
The supplier is obliged to ensure the seamless archiving of all quality-relevant documents and data for the purpose of
product liability / product safety.
The archiving of documents and data forms the secure technical foundation in case of recourse.
The archiving of quality-related data and documents subject to legal safekeeping requirements must be ensured for a
minimum period of two years for hard copies and ten years for soft copies.
Safekeeping periods exceeding the above legal minimum periods may also result from the life cycle of the corresponding
products with the user or from statutory periods of limitation for product liability cases or specific applicable legal
regulations, e.g. for products installed in plants.

9. Technical Requirements
The requirements and standards listed in this chapter shall apply unless other specifications are included in the product
specific documentation.
9.1. Mechanical components and assemblies
The independence principle as defined in ISO 8015 shall apply as a tolerance standard.
9.1.1. General tolerances
Applicable standards
ISO 1101: Geometrical product specifications (GPS) - Geometrical tolerancing - Tolerances of form, orientation, location
and run-out
ISO 5459 Geometrical product specifications (GPS) - Geometrical tolerancing - Datums and datum systems
ISO 2692 Geometrical product specifications (GPS) - Geometrical tolerancing - Maximum material requirement (MMR),
least material requirement (LMR) and reciprocity requirement (RPR)
ISO 14405 Geometrical product specifications (GPS) - Geometrical tolerancing - Dimensional tolerancing
ISO 5458 Geometrical Product Specifications (GPS) - Geometrical tolerancing - Positional tolerancing
ISO 1302 Geometrical Product Specifications (GPS) - Indication of surface texture in technical product documentation
ISO 2768 General tolerances
ISO 2768-1 Part 1: Tolerances for linear and angular dimensions without individual tolerance indications
ISO 2768-2 Part 2: Geometrical tolerances for features without individual tolerance indications
The general tolerances apply to the finished parts, including the surface according to DIN ISO 2768 Part 1 and 2. ASM AS
has defined the tolerance classes “m” (T1) and “H” (T2).
9.1.2. Fits
Applicable standards
ISO 286 Geometrical product specifications (GPS) – ISO code system for tolerances on linear sizes
ISO 286-1 Part 1: Basis of tolerances, deviations and fits
ISO 286-2 Part 2: Tables of standard tolerance classes and limit deviations for holes and shafts
This standard defines the fit systems of basic hole and basic shaft as well as the terms of main dimensions, fundamental
tolerances, tolerance zone, degree of tolerance and tolerance class.
9.1.3. Drilled / counter bored holes
Applicable standards
ISO 15065:2005 Countersinks for countersunk head screws with head configuration in accordance with
ISO 7721
ISO 13715 Technical product documentation—Edges of undefined shape—Vocabulary and
Indications
DIN EN ISO 15065 Counter bores for countersunk screws with standard heads according to ISO 7721
DIN 974-1 (Eng) Counter bores for cap screws
DIN 974-2 (Eng) Counter bores for hexagon head cap screws
ISO 273:1979 Fasteners – Clearance holes for bolt and screws
For blind holes, the specified dimensions for hole depths without specific tolerances should be considered as minimum
dimensions.
The edges that result from the production of drilled and counter bored holes must be free of burrs as defined in DIN ISO
13715.
19 www.asm-smt.com
As dimension “a” for the removal according to DIN ISO 13715, a deburred dimension of –0.1 to –0.5mm is defined unless
otherwise specified in the drawings.
The through-holes of the counter bored holes are produced according to ISO 273:1979, design “medium (m)”.
9.1.4. Threads
Applicable standards
DIN 13-1 ISO general purpose metric screw threads - Part 1: Nominal sizes for coarse pitch threads;
nominal diameter from 1 mm to 68 mm
ISO 3508 Thread run-outs for fasteners with thread in accordance with ISO 261 and ISO 262
DIN 78 Protrusion of bolt ends
DIN 7952 Sheet metal anchorage with threads; dimensions
ISO 261 ISO general purpose metric screw threads – General plan
ISO 262 ISO general purpose metric screw threads – Selected sizes for screws, bolts and nuts
ISO 965 ISO general purpose metric screw threads – tolerances
Dimensions for thread depths without specific tolerances should be considered as minimum dimensions.
Thread run-outs / undercuts shall be designed as for the standard described in ISO 3508.
Deviating from ISO 3508, a 90° counter bore is permitted for internal threads, where the diameter of the counter bore shall
be 1–1.05 x of the internal diameter of the thread.
Thread ends shall be produced according to DIN 78. For external threads, a 45°chamfer shall be added, with an
incomplete thread in the run-out area up to 2x P (P = thread lead) being permitted.
9.1.5. Quality of edges
Applicable standards
ISO 13715 Technical product documentation—Edges of undefined shape—Indication and dimensioning
The edges must be produced free of burrs according to DIN ISO 13715.
For machined parts (except plates and thin-walled parts), the dimension “a” (see DIN ISO 13715) shall be –0.1 to –
0.5mm.
For plate or thin-walled parts, it must be ensured that the width of the remaining surface between two deburred edges
does not become smaller than the dimension of the removed material. In cases where deburring causes new hazards of
injury, the edges shall be rounded in a suitable manner or the edge quality shall be coordinated with ASM AS.
9.1.6. Quality of bends
Applicable standards
DIN 9003 Aerospace; bending of sheets, plates and strips of steel and heat-resisting alloys, bending
radii, directions for design
The bending zones must be free from cracks and must not be coarse-grained.
9.1.7. Adhesive specifications
Applicable standards
When adhesive joints are required, the order documentation or drawings must include the corresponding information.
If such information is missing, this shall be clarified with ASM AS.
All adhesive joints shall be produced according to the relevant specifications of the adhesive manufacturers.
The retaining forces indicated in the documents are to be examined and documented by suitable measures, in order to
prove process security.
