What this site is and who publishes it
Hygienic Machinery Parts is an engineering knowledge site published by NHK Group ApS, Staermosevej, 5610 Assens, Denmark. It explains hygienic design, standards, materials and component selection. Guidance is not a substitute for a product specification, the applicable standard, certification assessment or application-specific engineering review.
Standards and sources
Guides refer to the standards and regulations they cite. The keyword-batch guides list those references under Standards and sources at the end of their main text. Older migrated pages retain their original text and do not yet all have this separate list. A source listing identifies the basis of a discussion; it does not establish that every numerical statement has been independently checked against the current edition.
Numbers quoted from standards may be rounded summaries. Check the current edition, clauses, test conditions and scope before using a value to specify or approve equipment. A general standards reference is not evidence that a particular NHK product meets it.
NHK product facts
The shared facts library records the source and evidence-check date for NHK contact details, product-line identities and certification claims. NHK product facts must be supported by NHK's own product documentation. Certificate scope must be checked for the specified design rather than applied to every product in a category. Official certificate references can supplement NHK documentation. See NHK's certifications.
Product-specific IP ratings, materials, test reports and field observations are not inferred from category names. Dedicated entries for new NHK-supplied data remain empty until supporting documentation is provided. The company legal name was supplied in the setup brief; current legal registration and any claim about offices in countries require NHK confirmation where public documentation does not establish them.
Worked examples
Worked examples are labeled Example and should identify their assumptions. They illustrate a method, not an NHK test report, customer installation or guaranteed performance. Confirm loads, operating conditions and supplier data for the actual application.
Dates and technical reviewers
Updated keyword-batch guides show Last updated and Last reviewed dates. For this initial setup, Last reviewed records an editorial source-list and presentation check, not a completed technical approval. The accompanying note states this distinction. Legacy pages without a recorded review are not assigned a review date merely because this setup changed the shared page template.
Every guide identifies NHK Group ApS as its publisher. A Technically reviewed by credit appears only when NHK has supplied a real person's name and job title and that person has been assigned to the guide. No technical reviewers are currently registered. No internal technical approval workflow is claimed.
