# Glossary > The words SpecLatch uses and the engineering terms in the guide's examples, one short definition each. Source: https://www.speclatch.com/guide/glossary Plan: Every plan. Last verified: 2026-11-11 App words first, grouped by where you meet them, then the domain terms the examples use. ## Workspace and people ### Organization Your company's workspace: its tables, records, members, settings and plan. Everything you create belongs to one organization. ### Member A person in the organization. Each member has a role and a visibility, both set on **Members**. New people join as Viewer. ### Role What a member may do: Admin, Engineering, Marketing or Viewer. Engineering builds tables and fields and edits and submits records, Marketing approves and publishes them, and a Viewer reads. Admin can do all of it, plus members and billing. ### Plan Your subscription: Starter, Growth or Professional. A trial runs with Growth features. The [pricing page](/pricing) lists what each plan includes. ## Tables and records ### Table A group of records that share the same fields, usually one product line. Every table is listed on **Tables**. ### Field One spec a table tracks, shown as a grid column. Its type comes from a gallery of nine: Text, Number, Yes / no, Date, Choice, Files, Link to records, From linked records and Calculated. ### Built-in columns Name, Model #, SKU and Description, which every table has. Name is always on; the other three can be hidden per table. ### Key A field's short code name, such as `bep_flow`. Formulas, imports and the API use it, so it can't change after the field is created. ### Field group A section name that gathers fields, such as Ratings & tests. Each group forms one section on the record page, spec sheets and the portal. ### Record One product in a table, one row in the grid. Each record has its own page with specifications, documents, comments and history. ### Saved view A grid layout kept under a name: filters, sorts, grouping and columns. Views are personal, or shared with the whole organization by an Admin or Engineering member. ### Preset A record saved as a starting point. **From preset…** in the **New record** menu creates a pre-filled draft from it. ### Tag A colored label any record can carry, such as Stock item. Catalog templates can filter on tags. Tags are managed on **Tags**. ### Trash Where a record goes when you click **Move to trash**. You can restore it for 30 days; then it is deleted for good. ### History The list of changes on a record page: each field change, with who made it and when. **Activity** shows changes across the whole organization. ### Completeness The percent shown beside a record's name, such as 80% complete. It counts the fields that are filled in and pass their rules. ## Units and formulas ### Unit The unit a number field stores its values in, such as psi or gpm. Each value is stored once and shown in imperial and metric, such as `132.6 ft · 40.4 m`. ### Calculated field A field whose value comes from a formula of other fields, written with their keys. The valve formula `cv_rated * 0.865` gives Kv from Cv. SpecLatch checks the formula's units before it saves. ### Function A formula with a name, defined once on **Functions** and called from any calculated field. A pump table might define hydraulic power this way. ### Reference table A lookup table your formulas read, such as a ball valve's Cv by percent open. Reference tables are listed on **Reference tables**. ### Link to records A field that connects records in two tables, such as a valve and its standard actuator. The link works both ways: the other table gets a matching field. ### From linked records A field that shows a value from linked records, or totals them. Its **Show** setting offers **Each value**, **Unique values**, **Count**, **Sum**, **Average**, **Lowest**, **Highest** and **Range (lowest–highest)**. ### Data series Multi-point X/Y data a record can carry, such as a pump's head curve. A table defines the axes once; each record then holds its own curve. ## Review and publishing ### Visibility tier The level a field, document or data series is set to: Public, Internal or Confidential. Each member and API key has a visibility too, the highest tier it can read. ### Status Where a record stands in review: Draft, In review or Published. Only Draft records accept edits. **Needs review** lists records waiting for a decision. ### Preview as An option in the grid's view menu that shows the grid as a lower tier sees it. Previewing is read-only. ### Document template The design of a spec sheet or catalog, laid out in a page designer. Templates are listed on **Templates**. ### Spec sheet A PDF of one record, built from a template and live data. Until the record is Published, you get a preview with a draft watermark. ### Catalog A PDF of a table's Published records, built from a template. Catalogs come with the Growth plan and up. ### Document library Every document in the organization on **Documents**: generated PDFs and uploaded files such as test reports and manuals. Each document has its own tier. ### Out of date A generated PDF that is older than the data it shows. The dashboard lists these under **Documents out of date**, with a **Regenerate all** button. ### Portal Your public catalog website. It shows Published records and Public fields from the tables you choose, on the Growth plan and up. ### API key A key that lets another system read your data through the read-only API. An Admin creates keys on **API keys**, on the Growth plan and up. ## Domain terms in the examples ### BEP (best efficiency point) The flow at which a centrifugal pump runs at its highest efficiency. Pump tables quote flow, head and efficiency at BEP. ### Head The energy a pump adds, stated as a height of liquid in feet. At a given flow, a pump makes about the same head in any thin liquid; the pressure rises with the liquid's density. ### NPSH required Net positive suction head required: the suction head, in feet, a pump needs at a given flow to avoid cavitation. ### Cv and Kv Valve flow coefficients. Cv is the flow of water in US gpm at a 1 psi pressure drop; Kv is m³/h at a 1 bar drop. Kv = 0.865 × Cv. ### NPS Nominal pipe size, the North American size designation for pipe and valve ends, such as NPS 2. DN is the metric designation, such as DN 50. ### Span The difference between the top and bottom of an instrument's range. A gauge reading 0 to 300 psi has a span of 300 psi, and its accuracy is often a percent of span.
